A European technology company closes a cross-border acquisition. Neither target nor acquirer has a Chinese subsidiary. Two months later, a letter arrives from China's State Administration for Market Regulation (SAMR): the deal triggered mandatory merger notification thresholds and closing without clearance was unlawful. The consequences – fines, remedial orders, and reputational exposure – arrive without warning. This scenario is not hypothetical. It plays out repeatedly as foreign businesses underestimate the reach of China's competition legislation.
Competition law compliance in China is governed primarily by anti-monopoly legislation administered by SAMR and, for policy matters, overseen by the State Council (China's supreme executive authority). Obligations fall into three main categories: pre-closing merger notification, prohibition of cartel conduct, and rules on the abuse of market dominance. Businesses that meet the relevant revenue thresholds must file with SAMR before completing a transaction, and failure to do so carries significant financial and operational consequences.
This guide covers the procedural requirements for each category of obligation, the step-by-step timeline from internal assessment to clearance or compliance sign-off. A documentary checklist, the most common errors made by international clients, indicative cost ranges. Additionally, a decision framework for different business scenarios.
The three pillars of China's competition law regime
China's competition law regime rests on three distinct branches of legislation: anti-monopoly law, rules on unfair competition, and sector-specific regulatory instruments issued by the State Council. For most international businesses, the anti-monopoly branch is the primary concern. It prohibits three categories of conduct: monopoly agreements (including cartel arrangements), abuse of a dominant market position, and concentrations of undertakings that harm or may harm competition.
Monopoly agreements cover horizontal arrangements between competitors – such as price-fixing, market allocation, and bid-rigging – as well as certain vertical agreements between suppliers and distributors. Horizontal arrangements are treated as per se violations. Vertical restrictions are assessed by reference to their actual or likely effect on competition in the relevant market.
The prohibition on abuse of market dominance applies to undertakings that hold a dominant position in a relevant market. Dominance is assessed by market share, together with factors including countervailing buyer power, barriers to entry, and the degree of dependence of other market participants on the dominant firm. Prohibited conduct includes predatory pricing, refusal to deal, exclusive dealing, and tying arrangements. SAMR has shown particular interest in digital platforms where network effects can create or entrench dominance rapidly.
The third pillar – merger notification – applies to concentrations of undertakings that meet prescribed revenue thresholds. This includes mergers, acquisitions of controlling interests, and the creation of joint ventures that perform all functions of an autonomous economic entity on a lasting basis. The obligation is pre-closing: parties may not complete the transaction until SAMR issues clearance or the review period expires without a decision.
A fourth layer – the leniency programme – sits alongside the prohibitions. It incentivises cartel members to self-report by offering fine reductions in exchange for evidence and cooperation. This instrument has grown in practical importance as SAMR's investigative capacity has expanded.
Step-by-step: from initial assessment to clearance or sign-off
The compliance process differs depending on whether the primary concern is a transaction requiring merger notification or an ongoing conduct issue. Both paths share a common first step: a structured internal assessment.
Step 1 – Internal threshold assessment (weeks 1–2). The first task is to determine whether the transaction or conduct in question falls within the scope of China's competition legislation. For merger notification, this means calculating the global and China-specific revenues of all parties against the applicable thresholds set out in anti-monopoly legislation. For conduct issues, it means auditing existing agreements and pricing practices against the rules on cartel conduct and market dominance. A wholly foreign-owned enterprise (WFOE) operating in China typically has more direct exposure to conduct rules, but even businesses without a Chinese legal presence can trigger notification obligations through sales into China.
Step 2 – Document collection and pre-filing preparation (weeks 2–6). If a merger filing is required, the parties must compile a comprehensive notification package. This includes corporate structure charts for all entities involved, financial statements demonstrating the revenue figures, market share data for each product or service market affected, and a description of the transaction rationale. SAMR may request supplementary information. The pre-filing period is also when counsel engage in informal dialogue with SAMR staff to identify likely concerns before formal submission.
The documentary checklist for a merger filing typically includes:
- Corporate certificates and ownership charts for all parties
- Audited financial statements for the most recent financial year
- A description of all affected product and geographic markets
- Market share estimates with supporting data sources
- Copies of the transaction documents in Chinese translation
Step 3 – Formal filing with SAMR (day 1 of review clock). The formal notification is submitted electronically through SAMR's filing portal. SAMR has up to 30 days from acceptance of a complete filing to conduct a phase-one review. Acceptance is not automatic: SAMR may request supplementary information before the clock starts. Incomplete submissions are a common source of delay and should be avoided through thorough pre-filing preparation.
Step 4 – Phase-one review (up to 30 days). During phase one, SAMR assesses whether the transaction raises competition concerns. Clearance at this stage is possible if the transaction is straightforward and the affected markets are not concentrated. SAMR may impose conditions even at phase one if parties offer remedies proactively.
Step 5 – Phase-two and extended review (up to 90 days, with possible 60-day extension). If phase one does not produce clearance, SAMR opens a phase-two investigation. This involves detailed market analysis, questionnaires to customers and competitors, and often requests for additional documents. Parties may negotiate remedies – structural (divestiture) or behavioural (supply commitments, interoperability requirements) – during this phase. In total, the review can extend to approximately six months from acceptance of a complete filing. For transactions in sensitive sectors, timelines have exceeded this in practice.
Step 6 – Post-clearance compliance or ongoing conduct programme. After clearance, any conditions imposed by SAMR must be implemented and monitored. For conduct matters that do not involve a transaction, the equivalent step is the adoption of an internal competition compliance programme. This includes written policies, staff training, and periodic audits of distribution and pricing arrangements. Businesses that identify a potential cartel issue at this stage must decide quickly whether to invoke the leniency programme before a competitor does.

Common errors by foreign clients and their consequences
Foreign businesses consistently repeat a small set of avoidable errors when managing competition law obligations in China. Each error carries a distinct consequence that escalates quickly once SAMR opens an investigation.
Assuming territorial limits. The most frequent mistake is the belief that China's merger notification rules apply only if one or both parties have a Chinese subsidiary or physical presence. In practice, the rules extend to any transaction where the parties collectively and individually meet the revenue thresholds from sales into China. A purely offshore deal between two European groups can fall squarely within mandatory notification requirements. Completing a notifiable transaction without filing – known as gun-jumping – attracts fines and may require the parties to unwind completed steps.
Underestimating market definition work. China's competition authority, SAMR, applies detailed market definition analysis. Parties that define their affected markets too broadly or narrowly in the filing create additional friction. SAMR's own analysis may produce a narrower market definition that yields higher implied market shares and triggers a deeper review. Investing in rigorous market analysis before filing saves time and reduces the risk of a phase-two investigation.
Failing to identify vertical agreement risks in distribution networks. International businesses entering China through distributor arrangements sometimes include resale price maintenance clauses that are unlawful under anti-monopoly legislation. Such clauses are frequently found in standard template agreements imported from other jurisdictions where they may be permissible. SAMR has actively pursued resale price maintenance cases, particularly in consumer goods and technology sectors. Audit of distribution agreements before entering the Chinese market is a non-negotiable step.
Delayed leniency applications. A business that discovers cartel conduct – whether its own or that of an industry group it participates in – faces a time-critical decision. The leniency programme rewards the first applicant most generously. A delay of even a few weeks can mean that a competitor files first, removing the prospect of full immunity. Many businesses hesitate while conducting internal investigations. The consequence is a significantly higher fine exposure.
Disputes arising from competition enforcement decisions can be challenged through administrative review and, where necessary, through litigation. The China International Economic and Trade Arbitration Commission (CIETAC) handles commercial arbitration in China, but competition enforcement decisions by SAMR are subject to administrative law processes rather than arbitration. Businesses should be clear about the distinction between contesting an enforcement decision and resolving a private competition law dispute with a counterparty, which may be subject to arbitration under a contractual clause. Our team's experience in corporate disputes in China covers both the administrative challenge and private litigation dimensions of competition matters.
Ignoring platform and data-related dominance risks. SAMR has published detailed rules on competition in the platform economy. Businesses operating digital marketplaces, app stores, or data-driven services in China face specific scrutiny over exclusive dealing practices, self-preferencing, and the use of data as a barrier to entry. A business that holds a strong position in a Chinese digital market and applies exclusivity conditions on merchants or users faces a real risk of investigation even without holding a formally dominant market share under the standard threshold approach.
Cost ranges and economics of compliance
Budgeting for competition law compliance in China involves three categories of expenditure: legal fees for substantive advice and filing preparation, government filing fees where applicable, and the internal management cost of the compliance process.
Legal fees for a straightforward merger notification. one that proceeds through phase one without complications. typically run into tens of thousands of euros in external counsel fees. Depending on the complexity of the affected markets and the volume of supplementary information requests. A phase-two investigation requiring economic analysis, remedy negotiation, and extended engagement with SAMR can increase external legal costs substantially. Businesses should treat phase-two cost as a multiple of phase-one cost when budgeting for complex transactions.
For competition compliance programmes – the ongoing conduct side – costs depend on the size of the business and the scope of the audit. An initial compliance audit for a medium-sized operation with multiple distribution agreements and a market share warranting dominance analysis will typically require several weeks of specialist legal work. Annual maintenance of the programme involves lower recurring costs.
The economics of non-compliance are stark. Fines for gun-jumping (completing a notifiable transaction without clearance) are capped under current legislation but the cap has been raised by legislative amendment in recent years, and SAMR has demonstrated willingness to impose substantial penalties. For cartel conduct, fines are calculated as a percentage of the previous year's sales revenue in the affected market. For abuse of market dominance, fines follow a similar revenue-based calculation. In each case, the fine is supplemented by the cost of remediation – unwinding transactions, amending agreements, and managing reputational damage.
The break-even calculation for investing in pre-filing advice and ongoing compliance is not difficult to make. The cost of a thorough compliance review is a fraction of the minimum fine exposure for a single violation. Businesses operating in China through a WFOE or through distribution and licensing arrangements should treat competition compliance as a recurring operational cost, not a one-time transaction expense.

Self-assessment checklist before taking action
The approach set out in this guide is applicable if one or more of the following conditions are present in your business situation.
Merger notification applies if: your planned transaction involves the acquisition of control over a business that generates revenue in China. the combined global revenues of all parties exceed the upper threshold in anti-monopoly legislation. and at least two of the parties individually meet the China-specific revenue threshold. If all three conditions are met, filing is mandatory before closing.
Cartel conduct review applies if: your business participates in trade association meetings or industry groups in China. your pricing or sales strategies are coordinated or aligned with competitors. or your distribution agreements include provisions on resale price or territorial exclusivity. Any of these conditions warrants a review of existing arrangements against the rules on monopoly agreements.
Market dominance analysis applies if: your business holds a strong position in any product or geographic market in China. Whether measured by market share, control of infrastructure. Alternatively, data advantages. or SAMR has previously identified your sector as a priority for enforcement. Businesses operating digital platforms should assume dominance scrutiny applies unless they have documented evidence to the contrary.
Before initiating the merger filing process, verify:
- Revenue calculations have been prepared using the correct accounting perimeter
- All affected product markets have been identified, including ancillary services
- Transaction documents are available in final or near-final form for translation
- A closing timeline has been set that accommodates SAMR's maximum review period
- Counsel experienced as a law firm in China with SAMR filing practice has been engaged
Decision framework by scenario:
- Cross-border M&A with China revenue exposure – begin threshold assessment at term sheet stage, not after signing
- Distribution network entry or restructuring – conduct agreement audit before execution, not after rollout
- Digital platform expansion – commission a dominance assessment before launching exclusivity conditions
- Suspected cartel participation – seek legal advice within days, not weeks, to preserve leniency priority

Frequently asked questions
Q: How long does merger notification review take in China?
A: SAMR applies a phased review timetable. Phase one lasts 30 days from acceptance of a complete filing. Phase two extends to 90 days, and a further extended phase can add up to 60 additional days. In practice, complex transactions involving large market shares or sensitive sectors frequently proceed through phase two, meaning businesses should budget at least four to five months from filing acceptance to clearance.
Q: Does a foreign-to-foreign merger require notification in China even if neither party operates there?
A: Yes – this is one of the most common misconceptions among international clients. China's merger notification rules apply whenever the combined revenue thresholds are met in China, regardless of where the merging parties are incorporated or where their assets are located. A purely offshore transaction between two non-Chinese companies can still trigger mandatory notification if both parties generate sufficient revenue from sales into the Chinese market.
Q: What does a leniency programme application involve and how much can it reduce fines?
A: China's leniency programme allows cartel participants to report their involvement to SAMR voluntarily and cooperate with the investigation. The first applicant to report and provide sufficient evidence can receive a significant reduction in fines or, in some cases, full immunity. Subsequent applicants receive smaller but still meaningful reductions. The process involves submitting a formal application, disclosing all relevant information about the cartel, and continuing to cooperate throughout the investigation. Engaging a lawyer in China with competition investigation experience is strongly advised before approaching the authority.
