China’s Anti-Monopoly Law (AML) is one of the most consequential pieces of commercial legislation affecting foreign businesses operating in or trading with China. Since its original enactment in 2008 and a sweeping overhaul that took effect on August 1, 2022, the AML has expanded in scope, sharpened enforcement tools, and introduced significant new compliance obligations. For any foreign company with a market presence, acquisition target, or supply chain relationship in China, understanding how the AML works is no longer optional.
The Legal Framework: What the AML Actually Covers
China’s AML is administered primarily by the State Administration for Market Regulation (SAMR), which was formed in 2018 by merging three formerly separate enforcement bodies. SAMR handles all three pillars of the AML:
- Monopoly agreements (Chapter II): cartels, price-fixing, bid rigging, and resale price maintenance
- Abuse of dominant market position (Chapter III): predatory pricing, exclusive dealing, tying arrangements, and refusal to deal
- Concentration of business operators (Chapter IV): merger control and acquisition filings
The 2022 amendments introduced several critical changes. Penalties for serious violations were raised from a maximum of 10% of annual turnover to up to 10% for standard violations, with a new provision for fines up to RMB 5 million even when turnover cannot be calculated. The revised law also codified rules on “hub-and-spoke” conspiracies, introduced safe harbor provisions for certain vertical agreements, and extended the law’s reach to cover platform economy companies more explicitly.
Merger Control: Foreign Deals That Require SAMR Filing
Merger control is the area where foreign businesses most frequently encounter the AML. Any concentration that meets SAMR’s notification thresholds must be reviewed before closing, regardless of where the merging parties are headquartered.
As of the thresholds set under the Provisions on Thresholds for Prior Notification of Concentrations of Business Operators, a filing is required if:
- The combined global turnover of all parties exceeds RMB 10 billion, and at least two parties each have China turnover above RMB 400 million; or
- The combined China turnover of all parties exceeds RMB 2 billion, and at least two parties each have China turnover above RMB 400 million
SAMR reviews take 30 days in Phase 1, extendable to 90 days in Phase 2, and up to 180 days in Phase 3 for complex cases. Most deals that clear review do so in Phase 1. However, deals in sensitive sectors — semiconductors, data, platform businesses, and strategic industries — face heightened scrutiny.
Notable foreign cases: SAMR blocked the Nvidia/Arm deal (abandoned in 2022), imposed conditions on SK Hynix’s acquisition of Intel’s NAND business, and reviewed numerous US-EU mergers specifically for China market effects. Foreign companies cannot assume that a deal approved in Washington, Brussels, or London will sail through Beijing.
Monopoly Agreements: Cartels and Vertical Restraints
Chapter II of the AML prohibits competitors from fixing prices, dividing markets, restricting output, or coordinating bids. These horizontal agreements are treated as per se violations under Chinese law — no efficiency defense is available.
Vertical agreements between suppliers and distributors — particularly resale price maintenance (RPM) — have been an enforcement priority for SAMR. Under the 2022 amendments, RPM is presumed to be anticompetitive but can be rebutted if the party can demonstrate procompetitive effects. This creates a rule-of-reason framework for RPM, which is a significant shift from earlier practice where many RPM arrangements were automatically treated as illegal.
For foreign brands selling through Chinese distributors, this has direct implications. Minimum advertised price (MAP) policies and strict territorial restrictions in distribution agreements need to be structured carefully and documented with procompetitive justifications. Engaging Chinese antitrust counsel before locking in distributor contracts is strongly advised.
Dominance and Platform Economy Enforcement
A company is presumed dominant under the AML if it holds a market share of 50% or more. SAMR can also investigate companies with lower shares if other structural factors apply. For foreign companies with strong positions in China’s industrial, technology, or consumer markets, dominant-firm rules create real compliance risk.
The 2022 amendments introduced explicit rules on platform economy operators, prohibiting self-preferencing, exclusive dealing requirements imposed on merchants, and use of data to foreclose competition. While the headline enforcement actions have largely targeted domestic platforms (Alibaba’s RMB 18.2 billion fine in 2021; Didi, Meituan), SAMR has made clear that foreign platforms with significant China presence are equally subject to these rules.
For foreign tech companies with China-facing products, the practical implication is this: any algorithmic ranking, default setting, or exclusivity clause that advantages your own products over rivals in the China market needs antitrust review before deployment.
Leniency and Compliance Programs
SAMR operates a leniency program for cartel participants who self-report. The first company to report a cartel and cooperate fully can receive immunity from fines. Subsequent reporters receive reductions of 50% and 30% respectively. This mirrors similar programs in the EU and US, but with a key difference: in China, the leniency process is less formalized and SAMR retains broad discretion over how cooperation is evaluated.
The 2022 amendments also formally recognized antitrust compliance programs as a mitigating factor in enforcement. SAMR published detailed compliance guidelines in 2020 that encourage companies to establish internal antitrust training, contract review procedures, and reporting channels. Multinational companies with existing global compliance programs should map those programs to China-specific AML requirements — they are not identical, particularly on vertical restraints and dominance standards.
Enforcement Trends in 2025 and 2026
SAMR has significantly ramped up enforcement activity since the 2022 amendments. Key trends relevant to foreign businesses include:
- Retroactive investigations: SAMR has reviewed deals that were previously below notification thresholds but had significant competitive effects, using a “call-in” power introduced in 2022.
- Cross-border data and IP: Licensing agreements that condition access to technology or data on exclusivity or cross-licensing requirements have drawn scrutiny under both the AML and the Anti-Unfair Competition Law.
- State-owned enterprise context: Foreign companies bidding against or partnering with SOEs should be aware that SOEs have historically received different treatment under dominance analysis, though SAMR has increased nominal parity in recent enforcement.
- National security overlap: Several SAMR merger reviews have been conducted in parallel with national security reviews under the Foreign Investment Law, adding complexity to deal timelines.
If you are structuring a joint venture with a Chinese state-owned enterprise, the interplay between AML merger control and Foreign Investment Law national security screening deserves specific legal analysis from the outset.
Practical Compliance Steps for Foreign Companies
Given the breadth of the AML and SAMR’s increasingly active enforcement posture, foreign businesses should implement the following concrete measures:
1. Pre-Transaction AML Assessment
Before any acquisition, joint venture formation, or significant distribution agreement in China, run a China AML analysis alongside your standard M&A legal review. Check SAMR’s notification thresholds early — and remember that even if thresholds are not met, SAMR can investigate deals post-closing if competitive concerns arise.
2. Distribution and Licensing Agreement Review
Audit your Chinese distribution contracts for RPM clauses, exclusivity terms, territorial restrictions, and most-favored-nation (MFN) provisions. The 2022 amendments changed the legal treatment of several of these clauses. Outdated contracts that were acceptable under pre-2022 practice may now create liability.
3. Internal AML Training
SAMR’s compliance guidelines specifically recommend training for sales, procurement, and business development teams — the employees most likely to engage in conduct that could trigger AML scrutiny. This is particularly important if your China team attends industry association meetings, where horizontal coordination risks are highest.
4. Monitor SAMR Publications
SAMR publishes enforcement decisions, merger conditions, and guidance documents on its official website at samr.gov.cn. For English-language analysis, the US-China Business Council regularly tracks AML developments that affect US companies specifically.
How the AML Interacts with Other Chinese Laws
The AML does not operate in isolation. Foreign businesses must understand how it intersects with:
- The Foreign Investment Law (2019): Prohibits expropriation and unfair treatment of foreign investors, but also creates a national security review track that can delay or block deals independently of AML review. Learn more in our guide to navigating China’s regulatory approval systems.
- The Data Security Law and Personal Information Protection Law (PIPL): Data-driven market positions are increasingly analyzed under the AML’s dominance provisions. Companies with large proprietary datasets operating in China face dual exposure.
- The Anti-Unfair Competition Law (AUCL): The AUCL covers commercial bribery, false advertising, and trade secret misappropriation. SAMR enforces both laws, and investigations sometimes begin under one law and expand to the other.

Takeaway
China’s Anti-Monopoly Law is a sophisticated, actively enforced competition regime with genuine extraterritorial reach. The 2022 amendments strengthened SAMR’s tools, extended coverage to the platform economy, and raised penalties substantially. For foreign companies, the days of treating Chinese competition law as a secondary concern are over.
The strategic imperative is straightforward: integrate AML compliance into your China market entry planning, your M&A deal processes, and your ongoing contract management. The cost of building compliance in from the start is a fraction of the cost of an SAMR investigation or a blocked deal.
