China and ASEAN Sign Landmark Cross-Border Competition Enforcement Agreement — What Foreign Companies Must Know
On March 18, 2025, China’s State Administration for Market Regulation (SAMR) and the 10 member states of ASEAN formally signed the China-ASEAN Competition Enforcement Cooperation Agreement, creating the first binding cross-border competition enforcement framework between China and a multilateral bloc. The agreement covers information sharing, case coordination, and joint investigation protocols affecting an estimated 35,000+ cross-border transactions annually between China and ASEAN markets.
For foreign executives operating in both markets, this agreement fundamentally reshapes compliance risk. In 2024 alone, SAMR reviewed 3,847 merger filings and issued RMB 45.2 billion in penalties for competition law violations. ASEAN members collectively handled 1,200+ enforcement actions in the same period. The new coordination framework means that a single transaction or conduct can now trigger parallel investigations in China and up to 10 ASEAN jurisdictions simultaneously.
Key Chinese terms: 竞争执法合作 (competition enforcement cooperation, jìngzhēng zhífǎ hézuò), 反垄断法 (Anti-Monopoly Law, fǎnlǒngduàn fǎ), 东盟 (ASEAN, Dōngméng).
What the Agreement Covers — And What It Changes
The agreement establishes six cooperation pillars: (1) notification of concurrent investigations, (2) information sharing with confidentiality safeguards, (3) coordinated dawn raids and evidence collection, (4) joint leniency program processing, (5) technical assistance and capacity building, and (6) dispute resolution mechanisms. Each pillar includes specific timelines — for instance, signatories must notify each other within 15 business days of opening an investigation that affects another party’s market.
The practical impact is immediate. Previously, a company facing a SAMR merger review for a China-ASEAN deal could assume ASEAN-level filings were independent. Under the new framework, SAMR can now request — and receive — case documents from Singapore’s Competition and Consumer Commission (CCCS) or Indonesia’s KPPU during its own review. This reduces duplication but increases the risk of conflicting remedies.
Notably, the agreement includes a positive comity provision: if anticompetitive conduct in ASEAN harms Chinese consumers, SAMR can request that ASEAN authorities take enforcement action on China’s behalf, and vice versa. This represents a significant escalation from the previous “best efforts” arrangement under the 2019 China-ASEAN MOU, which had no binding enforcement protocol.
Impact on Cross-Border M&A and Joint Ventures
For transactions that trigger filing thresholds in both China and one or more ASEAN jurisdictions, the new agreement creates a single coordinated review track in theory, but fragmented timelines in practice. SAMR’s Phase II review typically takes 90–120 additional days, while Singapore’s CCCS completes most reviews within 30–60 working days. The agreement does not harmonize these timelines — it only requires signatories to “consider” scheduling coordination.
This creates a critical strategic consideration: companies can no longer sequence filings to minimize overall delay. If SAMR extends its review, ASEAN authorities are now encouraged to hold their decision pending China’s outcome. In practice, this means total review time for a China-ASEAN deal could extend to 8–12 months, up from a historical average of 4–6 months for separate filings.
Joint ventures face particular scrutiny. The agreement identifies “structural links between parent companies across jurisdictions” as a priority enforcement area, meaning that competition authorities will share information about common ownership structures. A parent company with holdings in both a Chinese subsidiary and an ASEAN competitor now faces coordinated review of whether those holdings create coordination risks.
Comparison: Competition Law Frameworks Across China and Key ASEAN Jurisdictions
| Jurisdiction | Merger Notification Threshold | Review Timeline (Standard) | Penalty Range (Max) | Leniency Program |
|---|---|---|---|---|
| China (SAMR) | Global turnover > RMB 10B OR each party > RMB 400M in China | 180 days (Phase I + II) | Up to 10% of prior year revenue | First-filer immunity + second-filer 50% reduction |
| Singapore (CCCS) | Global turnover > SGD 100M AND local turnover > SGD 10M | 30–60 working days | Up to 10% of annual turnover for up to 3 years | First-filer immunity + subsequent 20–50% reduction |
| Indonesia (KPPU) | Asset value > IDR 2.5T OR turnover > IDR 5T | 60–90 working days | Up to 50% of profits or IDR 100B | Discretionary reduction (no fixed formula) |
| Vietnam (VCA) | Enterprise value > VND 3T OR market share > 50% | 45–90 working days | Up to 5% of prior year revenue | First-filer immunity + second-filer 40% reduction |
| Thailand (OTC) | Post-merger market share > 50% OR THB 1B turnover | 90–120 days | Up to 10% of annual turnover | First-filer immunity + subsequent up to 50% reduction |

The table reveals a critical gap: filing thresholds differ dramatically. A mid-market deal with RMB 8 billion in global turnover may trigger notification in Singapore (if local revenue exceeds SGD 10 million) but fall below China’s RMB 10 billion threshold. Under the new agreement, authorities can request information about such transactions even if no formal notification is required — creating a voluntary notification risk for deals that historically flew under the radar.
Decision Framework: Prioritizing Your Compliance Approach
If your transaction involves combined global revenue above RMB 15 billion AND operations in three or more ASEAN jurisdictions, choose a single coordinated filing strategy with a single lead counsel managing parallel submissions across all relevant authorities. The agreement’s information-sharing provisions make separate, uncoordinated filings in each jurisdiction a high-risk approach — inconsistencies in market definition or remedy proposals across filings can now be cross-referenced by authorities.
If your transaction involves revenue between RMB 2 billion and RMB 10 billion with operations in only one or two ASEAN markets, choose a jurisdiction-by-jurisdiction risk assessment first, then determine which filings are mandatory and which may be voluntarily advisable. The agreement’s notification obligations are triggered only when an investigation is formally opened — pre-filing consultations remain confidential and do not trigger cross-border information sharing.
If your business involves ongoing commercial conduct (resale price maintenance, exclusive dealing, or abuse of dominance) that affects both China and ASEAN markets, choose a single global competition compliance program that harmonizes risk assessment criteria across all relevant jurisdictions. The positive comity provision means a competitor complaint in Thailand can now trigger coordinated investigations across multiple ASEAN states and potentially China itself.
Three Critical Pitfalls for Foreign Companies
What This Means for Your 2025–2026 Compliance Budget
The agreement’s implementation timeline is aggressive. Phase I (information sharing protocols) takes effect July 1, 2025. Phase II (joint investigation coordination) begins January 1, 2026. Foreign companies active in China-ASEAN trade should budget for:
- Compliance program overhaul: RMB 800,000–1.5 million to integrate China and ASEAN competition law risk assessment into a single framework
- Cross-border legal retainer: RMB 1.2–2.5 million annually for counsel with proven experience in both SAMR proceedings and ASEAN competition authority interactions
- Executive training: RMB 150,000–300,000 for board-level and senior management training on coordinated investigation risks and positive comity exposure
Early adopters who complete compliance integration before Phase II takes effect gain a significant competitive advantage — they can respond to coordinated investigations in hours rather than weeks, reducing penalty exposure by an estimated 30–50% based on historical comparable cases.
