China has urged the United States to revoke unilateral trade tariffs, following a US Supreme Court decision that invalidated a significant portion of tariffs previously imposed by Donald Trump. The Chinese Ministry of Commerce stated that these measures violate international trade rules and US domestic law, serving no party's interests. While acknowledging the Supreme Court's ruling and assessing its impact, China also noted the US's intention to implement alternative measures, such as trade investigations, to maintain increased tariffs. China, a major trading partner of the US, has been a primary target of Trump's aggressive tariff policy, which has led to a prolonged trade war with global repercussions. The article also mentions that some tariffs were justified by the US's attribution of responsibility to China for the fentanyl crisis.
