Legal Analysis of China’s Retaliatory Tariffs Against the U.S. Decision to Impose Additional Tariffs

On February 1, 2025, an additional 10% tariff on all Chinese goods imported into the U.S. has become effective. This unilateral decision has sparked serious concerns regarding the violation of international trade laws, particularly World Trade Organization (WTO) regulations. In response, the Chinese government swiftly announced its intention to impose retaliatory tariffs on U.S. imports, effective February 10, 2025.

The Ministry of Finance of the People’s Republic of China, through the State Tariff Commission, issued Announcement No. 1 of 2025, which specifies that certain U.S. products will face increased tariffs, ranging from 10% to 15%. According to the announcement, products such as coal, liquefied natural gas (LNG), crude oil, agricultural machinery, and certain vehicles (including high-displacement cars and pick-up trucks) will be subject to these new tariffs. This action raises significant legal questions related to the principles of international trade law, the rights and obligations of member states under the WTO framework, and the legality of unilateral tariff measures.

Violation of WTO Principles

The U.S. imposition of tariffs on all Chinese imports—without clear evidence of a trade violation by China—appears to violate the foundational principles of the WTO, particularly the principles of non-discrimination and the most-favored-nation (MFN) treatment. These principles are enshrined in the General Agreement on Tariffs and Trade (GATT), the WTO’s cornerstone agreement. Specifically, Article I of GATT mandates that any tariff or trade restriction imposed by a member must be applied equally to all WTO members unless exceptions are made under specific circumstances.

The U.S. argument that its tariff imposition is driven by concerns over fentanyl-related issues seems to be a politically motivated measure, not directly related to any legitimate trade dispute or unfair trade practice by China. According to WTO jurisprudence, tariffs imposed for non-trade related reasons—such as domestic policy goals unrelated to trade—could be seen as unjustified and as violating the trade liberalization commitments made by the U.S. when it became a WTO member.

China’s Legal Response

In accordance with Chinese domestic law, including the Customs Law of the People’s Republic of China and the Foreign Trade Law, the Chinese government has the right to impose retaliatory tariffs in response to unfair trade practices. China’s countermeasures—imposing tariffs on a range of U.S. goods—are framed as a legal response to the U.S. violation of international trade norms.

From a legal perspective, the Chinese government’s action can be seen as a legitimate exercise of its right to protect its economic interests, provided it is done in accordance with both international and domestic law. This includes adherence to the WTO dispute settlement mechanism, where a member state is entitled to take retaliatory measures if it has been subject to a WTO-inconsistent action by another member. While the U.S. has not yet triggered a formal dispute settlement procedure within the WTO system, the imposition of these tariffs signals China’s readiness to challenge the U.S. decision on the international legal stage.

Compliance with WTO Dispute Settlement Procedures

The WTO’s dispute resolution process provides a structured framework for addressing trade disagreements between member states. If China believes that the U.S. tariffs violate its WTO commitments, it could initiate a formal dispute by requesting consultations with the U.S. under the WTO’s Dispute Settlement Understanding (DSU). If consultations fail, China could request the establishment of a panel to adjudicate the dispute.

It is important to note that retaliation through tariffs, as per WTO rules, is only allowed if a member state has already been found to be in breach of its obligations. Thus, any Chinese retaliatory tariffs imposed without a formal WTO ruling could be challenged by the U.S. in the future, unless the retaliatory actions are deemed proportionate and in line with international legal standards.

Broader Legal Implications

The ongoing tariff conflict between the U.S. and China is a reminder of the vulnerability of international trade relations to political considerations. While both parties are within their legal rights to impose tariffs, the underlying issue is one of fairness and adherence to global trade rules. If either country deviates from the established legal framework, it risks undermining the stability of the international trading system. The potential escalation of the dispute also brings into question the efficacy of the WTO as a mechanism for resolving complex trade disputes, especially when major economic powers are involved.

Furthermore, the legality of unilateral tariffs under international law is likely to remain a contentious issue, as countries like the U.S. may invoke national security exceptions or other justifications for such measures. However, these exceptions are limited and must be justified in accordance with the principles outlined in international agreements.

Conclusion

The legal ramifications of the U.S. decision to impose additional tariffs on Chinese imports and China’s retaliatory response have significant implications for the future of international trade law. Both countries must ensure that their actions comply with the WTO’s rules to avoid exacerbating tensions and potentially leading to a broader trade war. At the same time, the dispute highlights the challenges of balancing national interests with international legal obligations, as both countries seek to protect their economic and geopolitical interests through legal and diplomatic means. As the situation unfolds, the role of international trade law in maintaining global economic stability will be tested once again.
