Selling a Business to a Chinese Buyer: What Determines Whether the Deal Closes

Most cross-border deals that fail do not fail at the negotiating table. They fail at a regulator, on one side of the ocean or the other.
If a Chinese buyer has approached you about one of your business lines, the commercial terms are the part you already know how to handle. What determines whether the deal actually closes sits in three places outside the negotiation. Whether the US government requires a filing before you can close, which is a legal obligation and not a business judgment. Whether the buyer can obtain its own government's approval and get the money out of China, which changed substantially on July 1, 2026. If your own company is Chinese-owned, that same regime may reach your side of the deal as well. And whether your contract allocates those two risks to someone, because if it does not, the risk sits with you by default.
That last point deserves emphasis, because sellers routinely assume the opposite. You can be paid, closed, and gone, and still be exposed. Whether a later unwind reaches back to you depends entirely on what your purchase agreement says about representations, indemnities, and survival.
This article is about running that deal. We have written separately about what Chinese investment structures remain viable under current US policy, which answers whether a deal is possible at all. This one assumes you have decided to explore it.
Which Kind of Sale Are You Running
The analysis below applies with different force depending on what you are actually selling.
Lower regulatory friction if:
The business line makes a commodity product with no export-controlled technology
No US government or defense customers
No sensitive personal data on US individuals
You are selling assets that can be cleanly separated, with no shared IP or shared engineering staff
The buyer is a private Chinese company with no state ownership
Substantially higher friction if:
The business designs, develops, or manufactures anything requiring an export license to China
It performs one of the enumerated functions with respect to covered investment critical infrastructure
It holds personal data on US individuals at scale
The buyer is state-owned, state-invested, or has a government entity anywhere in its ownership chain
Engineering, IP, or key personnel are shared with the parts of the business you are keeping
If you are in the second list, the filing question is probably not optional, and the sections below on mandatory declarations and non-notified transactions are the ones to read closely.
There is a third case that is easy to miss. Some sellers are themselves Chinese-owned. If the US entity selling the business line is held by a Chinese parent or a Chinese individual owner, the analysis runs in both directions. The buyer's side is unchanged, but your own owner may face a PRC approval question on the way out, because selling is a disposition of that owner's outbound investment. That question is dealt with in the Decree 837 discussion.
CFIUS, TID Businesses, and Safe Harbor: What the Terms Mean
CFIUS is the Committee on Foreign Investment in the United States, an interagency committee that reviews foreign acquisitions of US businesses for national security risk. It is not a court and it does not publish decisions.
TID US business is the regulatory category that makes CFIUS filing obligations bite. A US business falls in it if it produces, designs, tests, manufactures, fabricates, or develops one or more critical technologies; performs one of the functions enumerated in the regulation with respect to covered investment critical infrastructure; or maintains or collects, directly or indirectly, sensitive personal data of US citizens (31 CFR 800.248). Note how narrow the first prong is. Selling or distributing a critical technology you did not make does not by itself put you in it. Whether your business line is a TID business is the threshold question in the entire analysis.
Substantial interest is asymmetric, and the asymmetry is easy to get backwards. Where a foreign person acquires an interest in a US business, it means a voting interest, direct or indirect, of 25 percent or more. Where the question is whether a single foreign state's governments have an interest in that foreign person, the threshold is 49 percent or more (31 CFR 800.244(a)). For indirect holdings, any interest of a parent is deemed to be a 100 percent interest in any entity of which it is a parent (31 CFR 800.244(c)), which is how a government stake several layers up gets attributed down the chain. A separate rule applies where the acquiring entity's activities are directed by a general partner or managing member (31 CFR 800.244(b)).
Covered transaction is the jurisdictional gate. CFIUS's mandatory filing rules apply only to transactions that fall within the regulatory definition, which reaches transactions that could result in foreign control of a US business and certain non-controlling investments in TID US businesses. If the deal is not a covered transaction, none of the filing obligations below attach. Establishing that it is, or is not, comes before everything else.
Declaration versus notice. A declaration is the short-form filing. A notice is the long-form one. Where a filing is mandatory, parties may elect to file a notice instead of a declaration (31 CFR 800.401(f)). The choice matters, because only a notice reliably ends the matter. On receiving a declaration, CFIUS may request that the parties file a full notice, tell them it cannot conclude action on the basis of the declaration, initiate a unilateral review, or clear the transaction (31 CFR 800.407(a)).
Safe harbor is what you get when CFIUS reviews a transaction and concludes all action. Treasury's own description is that, with limited exceptions, CFIUS and the President will not thereafter act on the transaction. It is the entire reason sophisticated sellers file even when they are not required to.
Selling a Business Line Is Harder Than Selling a Company
A whole-company sale transfers an entity. A carve-out has to invent one.
Everything the business line currently shares with the rest of your company has to be identified and then either transferred, licensed, replicated, or provided under a transition services agreement. In practice the hard categories are always the same. Intellectual property developed by engineers who worked across product lines. Software and systems licensed at the enterprise level, where the license may not permit transfer. Customer contracts with anti-assignment or change-of-control provisions. Employees whose roles span both sides. Shared suppliers, where your volume discount disappears when the volume splits.
For a cross-border buyer this compounds in two ways. First, whatever technology and know-how transfers with the business line may itself require export authorization, which feeds directly into the CFIUS analysis below. Second, a transition services agreement means you keep working alongside the Chinese buyer for a year or two after closing, which is a relationship you should price and paper deliberately rather than treat as a closing mechanic. Worth knowing what the other side inherits: the day after closing, the business you sold becomes a US subsidiary of a foreign parent, with its own compliance obligations that a transition services arrangement can pull you back into.
Selling a Business to a Chinese Buyer: When a CFIUS Filing Is Mandatory
Most sellers assume CFIUS is something you elect into if the deal looks sensitive. For a defined set of transactions that is wrong. The filing is required, and the parties, not just the buyer, are obligated to make it (31 CFR 800.401(a)).
Two situations trigger that obligation. Neither depends on the size of the deal.
Government ownership in the buyer. A filing is required where a covered transaction results in a foreign person acquiring a substantial interest in a TID US business, and the national or subnational governments of a single foreign state, other than an excepted foreign state, hold a substantial interest in that foreign person (31 CFR 800.401(b)). China is not an excepted foreign state. That list currently comprises Australia, Canada, New Zealand, and the United Kingdom.
Note where the two thresholds sit. Your buyer needs 25 percent or more of your business. The government needs 49 percent or more of your buyer. Both can be held indirectly, and the parent imputation rule means a provincial or municipal investment vehicle several layers up an ownership chain can be attributed straight down it. A buyer that presents as a private company is a diligence item, not an assumption.
Export-controlled technology. A filing is also required for a covered transaction involving a TID US business that produces, designs, tests, manufactures, fabricates, or develops critical technology for which a US regulatory authorization would be required to export, reexport, transfer, or retransfer that technology to the relevant foreign person (31 CFR 800.401(c)).
That second test has three features written into the regulation that sellers regularly miss.
The question is asked without giving effect to most license exceptions. You do not get to say a license would not actually be needed because an exception applies. With narrow exceptions specified in the rule, the analysis assumes no exception (31 CFR 800.401(c)(2)(i), (e)(6)).
The buyer is treated as if it were an end user of the technology (31 CFR 800.401(c)(2)(iii)).
And the determination is made based on the buyer's principal place of business for entities, or on nationality for individuals (31 CFR 800.401(c)(2)(ii)). An intermediate holding company in Cayman or Singapore does not by itself change the answer, because the test looks to principal place of business as the regulation defines it.
The deadline is real. A required declaration, or a notice filed in its place, must be submitted no later than 30 days before the completion date (31 CFR 800.401(g)(2)). And you cannot close on your own schedule afterward. The parties may complete only after CFIUS has informed them in writing that it has concluded all action, or that it is unable to complete action on the declaration (31 CFR 800.401(h)). If CFIUS rejects a filing or permits it to be withdrawn, the parties cannot close earlier than 30 days after resubmission, absent written approval from the Staff Chairperson (31 CFR 800.401(i)).
The Penalty Number Changed, and a Lot of Published Guidance Has Not Caught Up
The figure below is worth checking against whatever you have read elsewhere, because a great deal of otherwise reliable commentary still carries the old one.
Failure to comply with the mandatory filing requirement exposes a person to a civil penalty not to exceed $5,000,000 or the value of the transaction, whichever is greater (31 CFR 800.901(b)). The regulation was amended effective December 26, 2024, and the figure was raised substantially.
Separately, a declaration or notice submitted with a material misstatement or omission, or with a false certification, carries a civil penalty of up to $5,000,000 per violation (31 CFR 800.901(a)(1)). And the regulation expressly provides that 18 USC 1001, the federal false statements statute, applies to all information provided to CFIUS by any party to a covered transaction (31 CFR 800.901(h)).
The exposure runs to persons, and both sides of the transaction are parties to the filing obligation. A seller who assumed this was the buyer's problem has assumed something the regulation does not say.
Not Filing Is Not the Same as Avoiding CFIUS
Sellers tend to read the filing question as binary: file and deal with CFIUS, or skip it and avoid CFIUS. The second option does not exist.
If you file and CFIUS concludes all action, the transaction receives safe harbor and will not, with limited exceptions, be revisited. If you never file, nothing has been resolved. Treasury operates a program specifically directed at identifying transactions that were never notified, and where no notice was filed and no safe harbor granted, the Committee may determine whether the transaction falls within its jurisdiction and take steps to initiate a review.
The Congressional Research Service describes the consequence plainly: non-notified transactions remain subject indefinitely to future CFIUS review and to possible divestment or other action ordered by the President.
The asymmetry falls in an odd place for a seller. You will have been paid and moved on. The buyer, however, may years later be ordered to unwind a transaction that by then has been integrated into its business. Whether that comes back to you depends entirely on what your purchase agreement says about representations, indemnities, and survival. That is a drafting question, and it is addressed further below.
Decree 837: What Changed for Chinese Buyers on July 1, 2026
Sellers focus on whether Washington will approve the deal. The more common failure mode is that the buyer cannot perform, and the framework governing that changed on July 1, 2026.
On May 5, 2026, Premier Li Qiang signed State Council Decree No. 837, promulgating the Provisions of the State Council on Outbound Investment (《国务院关于对外投资的规定》; English renderings of the title vary). The regulation was adopted at the State Council's 83rd executive meeting on April 17, 2026, runs to 34 articles, and took effect on July 1, 2026. It is the first State Council-level administrative regulation directed specifically at outbound investment, and it sits above the ministerial rules from the National Development and Reform Commission, the Ministry of Commerce, and the State Administration of Foreign Exchange that have governed the area.
Four articles bear directly on whether your buyer can perform.
Scope. The regulation defines outbound investment to include directly or indirectly obtaining ownership, control, management rights, or other related rights in enterprises or assets in another country or region, through contributing assets or equity or by providing financing or guarantees. Investors covered include enterprises, other organizations, and resident individuals within China (Article 2). An acquisition of a US business line is squarely within it.
Procedures. Where an outbound investment requires approval or filing, information reporting, or cross-border fund registration, the investor must complete those procedures in accordance with national regulations, submit truthful materials, and cooperate with supervision (Article 12). These procedures, together with the foreign exchange rules that Article 14 leaves to other legislation, are what determine whether your buyer's money can actually leave China.
Security review. China now operates its own national security review over outbound investment. The State Council's investment and commerce authorities, together with other departments, review outbound investments and related transfers or dispositions of assets and rights that affect or may affect national security. Parties must cooperate and must comply with the review decision (Article 15).
The review runs on the way out, not only on the way in. Article 15 is not limited to acquisitions. It reaches outbound investments and the transfer or disposition of related assets and equity interests where these affect or may affect national security. A US business held by a Chinese owner is that owner's outbound investment, so selling it is a disposition of that investment. Read that way, a Chinese-owned US seller may face a PRC clearance question of its own, separate from anything the buyer needs.
This question is independent of CFIUS. If your buyer is American, there is no CFIUS filing at all, and the Article 15 question on your owner's side does not go away. Whether a particular sale falls within Article 15 is a matter of PRC law and of implementation that is still developing, so it belongs with PRC counsel early rather than at signing.
Consequences that reach a closed deal. An investor that fails to complete required approval or filing procedures, or that applies for them by submitting false materials, may be ordered to correct the failure, have unlawful gains confiscated, and be fined a proportion of the investment amount. An investor that refuses to correct may then be ordered to stop the investment and to dispose of the shares or assets within a specified period, at a higher proportional fine, with separate fines on the individuals directly responsible (Article 27). An investor that refuses to cooperate with the outbound security review, submits false materials, or fails to comply with the review decision faces correction orders, confiscation of gains, and fines; where national security is harmed, it may be barred from outbound investment for one to three years, and where the investment has already been made, it may be ordered to stop and to dispose of the shares or assets (Article 28).
Set that against the US side and the shape of the problem is clear. Both governments now have authority to order an unwind after closing, on independent grounds, under separate regimes.
Decree 837 is a framework regulation, and implementation will develop. Article 33 provides that specific measures governing outbound investment by individual Chinese residents are still to be issued by the investment and commerce authorities. What is written above reflects the text as published in the State Council Gazette. Advice on how a specific Chinese buyer's approvals will actually proceed requires PRC counsel.
Deal Terms That Allocate the Risk
Nothing above is avoidable. All of it is allocable, and the allocation happens in the purchase agreement rather than in the regulatory process.
The provisions that carry the weight are the closing conditions, and specifically which regulatory clearances are conditions and which are merely covenants to use efforts. A long-stop date, and what happens when it passes with approvals outstanding. A reverse break fee, which is the mechanism by which the buyer pays for the possibility that it cannot perform. Escrow or holdback sized against post-closing regulatory risk rather than only against ordinary indemnity claims. Representations about the buyer's ownership chain, including government interests, which is what your mandatory-filing analysis rests on. And the survival period for those representations, which should be long enough to be meaningful given that CFIUS review of a non-notified transaction is not time-limited.
Two questions specific to a Chinese buyer get skipped more often than the rest.
Who bears the cost and delay if CFIUS requires mitigation rather than clearing the deal outright. Mitigation can impose ongoing obligations that change what the buyer is actually acquiring.
And who bears the risk that the buyer's PRC approvals fail. A buyer negotiating in good faith will resist absorbing that. A seller who does not raise it has absorbed it.
What to Decide Before You Sign an LOI
Not a checklist. These are the decisions that have to be made, and most of them are not commercial.
Determine whether the business line is a TID US business. Critical technology, covered investment critical infrastructure, or sensitive personal data. This single question drives everything downstream, and it is a legal determination.
Diligence the buyer's ownership chain to the top. Government interests at any level, not just the entity across the table.
Get the export control classification done early. The mandatory-filing test is built on whether an export authorization would be required, so you cannot answer the CFIUS question without answering the export control question first.
Decide filing strategy before you agree to a timeline. Mandatory or not, declaration or notice, and whether you want safe harbor even if no filing is required.
Ask what approvals the buyer needs on its side, and ask for the specifics. Not whether it expects approval. Which approvals, from which authorities, on what timetable.
If your own owner is offshore, ask the same question of your own side. A Chinese-owned US seller may need PRC clearance to dispose of the business, not only the buyer to acquire it.
Bring counsel in before the letter of intent. Timelines, conditions, and break fees are much harder to negotiate after a term sheet has set expectations.
If a Chinese buyer has made an approach and you are working out whether to engage, the question is not whether the price is right. It is whether the deal can close, who pays if it cannot, and what happens if a regulator revisits it after you have banked the proceeds.
Frequently Asked Questions
Can I sell my business to a Chinese buyer at all?
There is no general prohibition on selling a US business to a Chinese buyer. But for a defined set of transactions a filing is required before closing, the review regime has tightened in recent years, and a transaction that is never filed stays open to review indefinitely. So the practical question is not permission but process: whether your business line falls into one of those categories, how long clearance will take, and who carries the risk if it does not come. US policy toward Chinese investment has tightened in recent years, and we cover what that means for deal structure in Chinese Investment in US Businesses: 2025 Rules.
Is a CFIUS filing always required when a Chinese buyer acquires a US business?
No. Filing is mandatory only for defined categories of transactions. Two are central: a covered transaction resulting in the acquisition of a substantial interest in a TID US business by a foreign person in which a foreign state's national or subnational governments hold a substantial interest (31 CFR 800.401(b)), and a covered transaction involving a TID US business that produces, designs, tests, manufactures, fabricates, or develops critical technology for which a US regulatory authorization would be required to export or transfer that technology to the relevant foreign person (31 CFR 800.401(c)). Outside those categories, filing is voluntary. Voluntary does not mean advisable to skip, for the reasons in the next answer.
What actually happens if we just don't file?
Nothing is resolved. Where no notice has been filed and no safe harbor granted, CFIUS may determine whether a transaction falls within its jurisdiction and take steps to initiate a review, and Treasury operates a program directed at identifying such transactions. The Congressional Research Service states that non-notified transactions remain subject indefinitely to future CFIUS review and to possible divestment or other action mandated by the President. If the filing was mandatory rather than voluntary, there is a separate penalty exposure of up to $5,000,000 or the value of the transaction, whichever is greater (31 CFR 800.901(b)).
Our buyer says it is a private company, not state-owned. Is that the end of the analysis?
No. The mandatory filing trigger at 31 CFR 800.401(b) turns on whether the national or subnational governments of a single foreign state hold a substantial interest in the acquiring foreign person, which for that purpose means a voting interest, direct or indirect, of 49 percent or more (31 CFR 800.244(a)). Indirect interests count, and any interest of a parent is deemed to be a 100 percent interest in any entity of which it is a parent (31 CFR 800.244(c)). Provincial and municipal investment vehicles frequently appear several layers up an ownership chain that looks private at the top. Verify the chain rather than relying on a characterization, because the filing obligation runs to the parties and the penalty for getting it wrong is substantial.
We are selling a division, not the whole company. Does that change the CFIUS analysis?
The threshold questions are the same, but the answers can differ from what they would be for the whole company. What matters is whether the business being acquired is a TID US business, and a division may qualify where the parent as a whole would not, or the reverse. Carve-outs also raise a question that whole-company sales do not: what technology, data, and personnel actually transfer with the business line. Because the mandatory filing test at 31 CFR 800.401(c) is built on whether an export authorization would be required for the technology involved, the scope of what transfers can determine whether a filing is required at all.
Why does the timing matter so much?
Because you cannot close on your own schedule. A required declaration must be submitted no later than 30 days before the completion date (31 CFR 800.401(g)(2)), and the parties may complete only after CFIUS informs them in writing that it has concluded all action or cannot complete action (31 CFR 800.401(h)). If a filing is rejected or withdrawn and resubmitted, the parties cannot close earlier than 30 days after resubmission, absent written approval from the Staff Chairperson (31 CFR 800.401(i)). A purchase agreement drafted without those constraints in mind will have a long-stop date that does not work.
What changed for Chinese buyers on July 1, 2026?
State Council Decree No. 837, the Provisions of the State Council on Outbound Investment (《国务院关于对外投资的规定》), took effect that day. Signed by Premier Li Qiang on May 5, 2026 and running to 34 articles, it is the first State Council-level administrative regulation directed specifically at outbound investment, and it sits above the ministerial rules from the NDRC, the Ministry of Commerce, and SAFE that have governed the area. For a US seller the significant points are that acquisitions of foreign businesses fall within its scope (Article 2), that approval or filing, information reporting, and cross-border fund registration procedures must be completed as required (Article 12), and that China now conducts its own national security review of outbound investment with authority to order an investor to dispose of shares or assets already acquired (Articles 15 and 28). How this operates in a specific transaction requires PRC counsel.
Our US company is owned by a Chinese parent. Does that change anything for us as the seller?
Potentially, and it is easy to miss because the attention goes to the buyer's approvals. Article 15 of State Council Decree No. 837 provides for a national security review covering outbound investments and the transfer or disposition of related assets and equity interests where these affect or may affect national security. A US business held by a Chinese owner is that owner's outbound investment, so selling it is a disposition of that investment. On that reading your parent may have a PRC clearance question of its own, independent of the buyer's, and independent of CFIUS: if the buyer is American there is no CFIUS filing, but the Article 15 question remains. Article 28 attaches consequences to failing to cooperate with the review or to comply with its decision, including a bar on outbound investment for one to three years. Implementing measures are still developing, so this belongs with PRC counsel before a letter of intent rather than after.
Should we file voluntarily even if we are not required to?
It depends on the facts, and it is a real decision rather than a formality. The argument for filing is safe harbor: a transaction that CFIUS reviews and on which it concludes all action will not, with limited exceptions, be revisited. The arguments against are cost, disclosure, and calendar. What tips the analysis is usually the seller's tolerance for a post-closing unwind and what the purchase agreement says about who absorbs that risk. This should be decided before the letter of intent, not after signing.
