MOFCOM Issues Blocking Order Against U.S. Sanctions on 5 Chinese Firms

On May 3, 2026, China’s Ministry of Commerce (MOFCOM) issued Announcement No. 21, invoking the Measures for Blocking the Improper Extraterritorial Application of Foreign Laws and Measures to prohibit domestic entities from recognizing, enforcing, or complying with U.S. unilateral sanctions targeting five Chinese enterprises—including Hengli Petrochemical (Dalian) Refining & Chemical and Luqing Petrochemical—for their involvement in Iran-related oil transactions. This development directly affects energy and chemical exporters, international importers, distributors, and financial service providers engaged in cross-border trade with China—particularly those operating in the Middle East, Southeast Asia, and Latin America.

Event Overview

On May 3, 2026, MOFCOM published Announcement No. 21. The announcement explicitly prohibits Chinese individuals and entities from acknowledging, implementing, or abiding by U.S. sanctions imposed on five Chinese enterprises due to their participation in Iran petroleum trade. The prohibition is grounded in China’s Measures for Blocking the Improper Extraterritorial Application of Foreign Laws and Measures. The listed enterprises include Hengli Petrochemical (Dalian) Refining & Chemical and Luqing Petrochemical, among three others not named in the source material.

Which Subsectors Are Affected

Direct Export Trading Enterprises

These firms engage in cross-border sales of refined petroleum products and petrochemicals to buyers in Iran-adjacent markets or jurisdictions sensitive to U.S. secondary sanctions. They face immediate exposure to conflicting compliance obligations: U.S. sanctions risk versus MOFCOM’s blocking order. Impact manifests in contract enforceability, letter-of-credit issuance, and payment routing—especially where correspondent banks decline processing due to U.S. dollar clearing concerns.

Import-Dependent Distributors & Wholesalers (Middle East, Southeast Asia, Latin America)

Distributors relying on Chinese-sourced naphtha, fuel oil, or specialty chemicals may encounter delays or rejections in settlement if their banking partners apply U.S. sanctions screening. The blocking order does not override foreign banks’ internal compliance policies; thus, transaction friction persists even where Chinese law forbids compliance with the underlying sanctions.

Supply Chain Finance & Trade Service Providers

Factoring companies, trade insurers, and logistics coordinators facilitating China–third-country energy shipments must now assess whether their contractual terms reference U.S. law or jurisdiction—and whether operational workflows (e.g., document verification, fund disbursement triggers) inadvertently require adherence to prohibited measures. Their exposure lies in contractual liability, not just regulatory penalty.

Downstream Processing & Blending Facilities Abroad

Overseas refineries or blending units sourcing feedstock from the five sanctioned Chinese firms may face downstream scrutiny from local regulators or lenders assessing ESG or sanctions-linked counterparty risk—even if the end-use product has no Iranian nexus. The MOFCOM order does not mitigate third-party risk perception.

What Relevant Enterprises or Practitioners Should Monitor and Do Now

Track Official Clarifications and Enforcement Guidance

MOFCOM’s announcement is procedural, not prescriptive: it invokes authority but does not specify penalties, reporting requirements, or exemption pathways. Enterprises should monitor follow-up notices—especially any MOFCOM or SAFE (State Administration of Foreign Exchange) guidance on documentation standards for demonstrating non-compliance with prohibited foreign measures.

Map Exposure by Transaction Geography and Payment Channel

Firms should identify which contracts, invoices, or LCs involve jurisdictions where U.S. correspondent banking dominates (e.g., UAE-based USD settlements), and flag counterparties whose own compliance frameworks explicitly incorporate U.S. sanctions lists—even if those counterparts are outside U.S. jurisdiction. Prioritize review of contracts governed by English or New York law.

Distinguish Between Legal Prohibition and Operational Reality

The blocking order prohibits *domestic* compliance with U.S. sanctions—but does not compel foreign banks or overseas buyers to disregard them. Businesses should avoid assuming that MOFCOM’s stance eliminates practical barriers; instead, treat it as a legal baseline for internal policy alignment and intergovernmental dialogue—not as an operational override.

Prepare Contingency Documentation and Internal Protocols

Update internal compliance manuals to reflect the prohibition; retain records showing active steps taken to avoid implementing prohibited measures (e.g., rejected sanction clauses in drafts, revised payment instructions). Where possible, revise standard contracts to exclude references to foreign sanctions regimes and affirm governing law as PRC law—without triggering buyer pushback on enforceability.

Editorial Perspective / Industry Observation

Observably, this announcement functions primarily as a declaratory instrument—not yet an enforcement milestone. It signals Beijing’s institutional readiness to activate domestic blocking tools in response to extraterritorial sanctions targeting strategic energy supply chains. Analysis shows it is less about immediate disruption and more about establishing a legal anchor point for future disputes, diplomatic negotiation, and domestic accountability. From an industry standpoint, the measure reinforces that compliance frameworks must now account for layered, non-harmonized legal demands—not just ‘which law applies,’ but ‘which law’s application is actively blocked.’ Continued monitoring is warranted, particularly for MOFCOM’s potential designation of ‘unjustified foreign measures’ under Article 7 of the Blocking Measures, which could trigger mandatory reporting and mitigation plans.

This announcement underscores a structural shift: regulatory risk in global energy trade is increasingly bifurcated—not between ‘sanctioned’ and ‘non-sanctioned,’ but between jurisdictions asserting competing claims over the legality of third-country commercial conduct. For firms operating across multiple legal domains, the priority is not choosing one regime over another, but documenting deliberate, defensible choices within each.
