China’s merger control regime operates under the Anti-Monopoly Law, which became effective in 2008 and received updates in 2022. The law establishes guidelines for reviewing mergers, acquisitions, and other transactions that may reduce competition. Enforcement falls to the State Administration for Market Regulation, known as SAMR, which conducts investigations and issues final decisions.
How the system works
The regime requires companies to notify SAMR of qualifying deals before closing and prohibits completion until approval is granted. Foreign-to-foreign transactions are not exempt; if turnover thresholds are met, the deal must be filed regardless of where the parties operate.
SAMR’s Anti-Monopoly Enforcement Department II handles reviews. Parties can appeal decisions internally within the agency and later in Chinese courts. While the system is national, SAMR has assigned some straightforward filings to provincial branches to accelerate processing. This delegation does not create a separate process but remains part of the unified system.
Turnover serves as the sole jurisdictional test. A deal must be notified if either of two conditions is met: combined global turnover of all parties exceeds CNY 10 billion (about $1.4 billion) and at least two parties each have CNY 400 million in China sales, or combined China turnover exceeds CNY 2 billion and at least two parties each have CNY 400 million in the country. The thresholds are not cumulative, and the agency can adjust them based on economic conditions.

What counts as a concentration
The law defines a concentration broadly. It includes mergers, acquisitions of control through equity or assets, and any arrangement—such as contracts or options—that grants one company decisive influence over another. Control may be legal or de facto, positive or negative, and extends to veto rights over budgets, business plans, or senior management appointments.
Minority stakes can trigger a filing if they include strategic veto rights. No minimum shareholding threshold exists, and the agency has reviewed deals involving holdings well below 50% where the buyer gained control over key decisions. Temporary changes in control may also require notification, with no exemption for short-term arrangements.
Joint ventures are notifiable when jointly controlled by two or more parties and meet the turnover thresholds. The regime does not differentiate between full-function and non-full-function joint ventures as the EU does. A joint venture controlled by a single parent typically falls outside merger control but may still be evaluated under the AML’s general provisions.
Multiple transactions between the same parties within two years can be treated as a single concentration if they result in the same change in control. The notification obligation arises before the first step is implemented, and failure to file may lead to fines for gun-jumping. The agency also reviews interdependent transactions—such as asset swaps or coordinated deals—as a single concentration if they share the same economic purpose.
Exemptions and enforcement
The only clear exemption applies to intra-group restructurings where one company already controls at least 50% of the others involved. No de minimis exemptions exist for small-scale mergers that meet the thresholds, nor are there carve-outs for short-term financial holdings.

SAMR can intervene in transactions that should have been notified but were not. It may act before closing, inviting parties to discuss whether a filing is necessary, or after closing, requiring a filing within 30 days. If a deal is found to be notifiable but was not filed, the agency can impose fines up to 10% of the parties’ turnover if competition is harmed, or up to CNY 5 million otherwise. It may also order divestitures or unwinding of the transaction.
The agency holds discretion to review below-threshold deals if evidence suggests potential anti-competitive effects. While used infrequently, this authority has been applied in sectors like semiconductors, digital platforms, and pharmaceuticals, where national interests or key technologies are involved. No time limit restricts SAMR’s ability to investigate unnotified or below-threshold mergers, meaning historical deals can still face scrutiny if they continue to affect competition in China.
Companies may file voluntarily for deals below the thresholds if they anticipate competition concerns or seek to avoid future regulatory risk. Voluntary filings receive the same assessment as mandatory ones and provide legal certainty once cleared.
Notification becomes mandatory once parties reach a legally binding agreement, such as a signed share purchase or joint venture contract. Pre-signing filings are not permitted. The acquiring party bears primary responsibility for filing, though other involved companies must cooperate. No filing fee applies.

China’s standstill obligation is strict. Notifiable deals cannot proceed in any form before SAMR clearance. Gun-jumping includes completing business registration, transferring ownership, appointing senior management, or integrating business operations. Violations may result in fines and orders to restore the pre-deal state. The agency may also impose hold-separate measures during review to maintain separate operations.
Uncertainty can persist long after a deal closes due to the lack of a formal longstop date. The absence of sector-specific thresholds or local nexus requirements means even foreign-to-foreign transactions with no physical presence in China may be subject to review if turnover thresholds are met. The broad definition of control and the potential to aggregate related transactions add complexity.
Early engagement with the agency often proves beneficial. SAMR has demonstrated flexibility in working with parties on remedy design and procedural questions, particularly in cross-border deals requiring coordination with foreign competition authorities. Recent reforms, including updated notification thresholds and new guidelines, indicate a shift toward more consistent review practices, though the core framework remains unchanged.
The adjustments may not ease the burden on companies, but they could improve predictability. For now, the requirement is straightforward: if a deal meets the thresholds, file early, wait for clearance, and expect close scrutiny from the agency.
