China’s Landmark Merger Unwind: Unpacking the Wuhan Yongtong/Shandong Huatai Case from a Practitioner’s Perspective | Dacheng

Since China’s Anti-Monopoly Law (AML) was implemented in 2008, the nation has reviewed over 6,000 concentrations. While most were cleared unconditionally and conditional decisions primarily involved behavioral remedies, an unwind order had never been issued—until July 23, 2023. On this date, China’s antitrust authority, the State Administration for Market Regulation (SAMR), issued its first “merger unwind” order, compelling Wuhan Yongtong Pharmaceutical Co., Ltd. (Wuhan Yongtong) to divest its 50% stake in Shandong Huatai Pharmaceutical Co., Ltd. (Shandong Huatai), a downstream company acquired in 2019. This landmark decision signals a more proactive and expansive approach to China’s merger control, holding significant implications for any company doing business in China.

1. The Wuhan Yongtong/Shandong Huatai Unwind: A Detailed Overview

The case centers on Wuhan Yongtong, a key supplier of papaverine hydrochloride active pharmaceutical ingredients (APIs), and its 2018 acquisition of a 50% stake in Shandong Huatai, a downstream producer of papaverine hydrochloride injections. This vertical integration was central to the competitive dynamics.

Prior to the acquisition, in September 2016, Wuhan Yongtong secured an exclusive national distribution agreement for papaverine hydrochloride APIs from Qinghai Pharmaceutical Co., Ltd., gaining significant control over this critical input.

The 2018 acquisition of Shandong Huatai was implemented in 2019. Crucially, the transaction did not meet statutory notification thresholds, thus Wuhan Yongtong was not obligated to notify SAMR at the time.

However, based on evidence of anticompetitive effects, SAMR formally requested notification on January 3, 2025. Following review, SAMR concluded the acquisition was anticompetitive, significantly increasing Shandong Huatai’s market share in papaverine hydrochloride injections and leading to substantial price increases. The final decision mandated two remedies:

• Divestiture: Wuhan Yongtong must transfer its 50% stake in Shandong Huatai to a third party.
• Termination of Exclusive Distribution Agreement: Wuhan Yongtong must end its exclusive API distribution agreement with Qinghai Pharmaceutical.

This decision highlights SAMR’s commitment to addressing anticompetitive practices, even in non-notifiable, completed transactions.

2. Defining Features of the Landmark Ruling

The Wuhan Yongtong/Shandong Huatai case is precedent-setting for several reasons:

1. The Unprecedented Unwind Order

This marks China’s inaugural “merger unwind” order, a significant departure from previous ex-ante reviews. The acquisition, finalized in 2019, was reviewed nearly six years later, demonstrating SAMR’s authority to intervene in consummated concentrations and effectively order a restoration of the status quo ante, setting a powerful precedent.

2. Below-Threshold Scrutiny: A New Enforcement Frontier

This is the first publicly disclosed instance where SAMR compelled notification and effectively prohibited a non-notifiable transaction. The AML’s 2022 amendment (Article 26) empowers SAMR to require notification for below-threshold deals with competitive concerns. In this case, SAMR initiated the filing requirement based on evidence of anti-competitive effects, showcasing its proactive enforcement under expanded powers.

3. A Rare Prohibition: The Fourth in China’s History

This case is only the fourth such instance in China’s merger control history. Out of over 6,000 reviews, more than 90% were unconditionally approved. Previous prohibitions include Coca-Cola/Huiyuan (2009), P3 Network (Maersk, MSC, CMA CGM) (2014), and Huya/Douyu (2021). Its addition to this exclusive list underscores SAMR’s readiness to impose stringent remedies against significant threats to market competition.

3. Antitrust Focus: The Pharmaceutical Sector in China

The pharmaceutical sector is a key focus area for antitrust enforcement in China, given its public health importance, complex supply chains, and potential for market power abuse.

The pharmaceutical sector, particularly concerning APIs, is inherently prone to anticompetitive concerns. This vulnerability stems from its high market concentration, significant barriers to entry, and low demand substitution, which collectively foster environments where dominant firms can easily stifle innovation or inflate prices.

Antitrust enforcement in the pharmaceutical sector in China is robust, covering abuse of dominance, cartel agreements and administrative monopoly. For the regime of merger control, it is not rare for SAMR to issue conditions to mergers in this industry. It is not worthy that the first conditional approval for a non-notifiable transaction (the Simcere/Tobishi in 2023) also occurred in this industry, highlighting SAMR’s early and consistent attention to the sector. This vigilant scrutiny confirms SAMR’s recognition of the pharmaceutical sector’s direct impact on public welfare and its commitment to ensuring fair competition within it.

4. Strategic Implications for Businesses

The Wuhan Yongtong/Shandong Huatai case has profound implications for businesses in China, necessitating a re-evaluation of compliance strategies.

1. Beyond Thresholds: The Imperative for Competitive Assessment

Transactions below statutory notification thresholds are not immune from antitrust scrutiny. Companies with significant market presence are recommended conducting a thorough competitive impact assessment for all M&A activities, irrespective of turnover thresholds. Seeking legal advice for these assessments is crucial given the severe consequences of a post-completion unwind.

2. Post-Merger Scrutiny: SAMR’s Expanded Toolkit

While post-concentration anticompetitive conduct was typically addressed via abuse of dominance or cartel provisions, this case indicates SAMR’s willingness to use merger control powers, including unwind orders, for completed concentrations. This practice means SAMR is prepared to apply structural remedies retrospectively if the concentration itself is the root cause of significant competitive harm, offering a more effective way to restore competition than behavioral remedies.

3. Enduring Risk: No Statute of Limitations for Unnotified Deals

The fact that the Wuhan Yongtong/Shandong Huatai acquisition was completed in 2019, nearly six years before SAMR’s decision, sends a powerful message: transactions implemented years ago are still subject to potential antitrust review and intervention. There’s no explicit statute of limitations for SAMR to investigate unnotified, anticompetitive concentrations. This creates uncertainty, meaning companies cannot assume past inaction implies approval. Maintaining meticulous records and continuous antitrust compliance monitoring are essential.

This case marks a significant evolution in China’s antitrust enforcement, signaling SAMR’s proactive stance and expanded reach. It serves as a crucial reminder for all businesses operating in China to conduct rigorous competitive assessments, and remain vigilant to the enduring risk of review, regardless of deal size or completion date. This new era of enforcement demands heightened awareness and strategic adaptation to navigate China’s dynamic regulatory landscape effectively.
