Summary
In April 2026, China implemented two new regulations (Decree 834 and Decree 835) aimed at enhancing supply chain security and countering foreign extraterritorial jurisdiction. These laws create legal complexities for UK and EU companies with ties to Chinese supply chains, as they must navigate conflicting obligations. Decree 834 establishes a framework for protecting critical sectors, while Decree 835 allows for investigations and penalties against foreign companies that violate Chinese law. The regulations have already been enforced in relation to an investigation by the European Commission. Businesses are advised to assess their exposure and compliance with these new requirements. The laws may particularly affect sectors like solar, wind, and semiconductors, which are deemed critical by China. Legal and compliance teams must act promptly to address these developments. Key Points: • China's Decree 834 and Decree 835 impose new supply chain security regulations. • UK and EU companies face legal conflicts due to these new Chinese laws. • Immediate compliance action is required to navigate these complex regulations.
Detailed Analysis
**Impact** UK and EU companies with supply chains connected to China, particularly in critical sectors such as solar, wind, batteries, rare earth processing, semiconductors, and advanced manufacturing, are affected. The new Chinese laws impose legal and operational risks, including potential restrictions on export/import activities and investment in China, as well as visa limitations for key personnel. Multinational businesses conducting supply chain due diligence, including those subject to the EU Corporate Sustainability Due Diligence Directive, face conflicting compliance demands. The scope includes both direct industrial supply chain actors and ESG data platforms handling Chinese supply chain information. **Technical Details** The event involves regulatory enforcement rather than a cyberattack; no specific attack vectors, malware, CVEs, or infrastructure details are provided. The Chinese State Council Orders No. 834 and 835 establish legal frameworks to control supply chain security and counter foreign extraterritorial jurisdiction, with enforcement powers including investigations and trade restrictions. No indicators of compromise (IOCs) or technical TTPs are mentioned. **Recommended Response** Legal and compliance teams should urgently assess exposure to the new Chinese regulations and review supply chain due diligence practices to align with both Chinese and foreign regulatory requirements. Monitor enforcement actions under Orders No. 834 and 835, especially regarding investigations or trade restrictions affecting critical sectors. Businesses should maintain awareness of evolving definitions of key terms such as “normal market transaction principles” and “discriminatory measures.” No technical patches or detection rules are applicable based on current information.
