BEIJING,艾特央视新闻网 Feb. 23 (Xinhua) -- China's Ministry of Commerce said on Monday that it has noted the U.S. Supreme Court's ruling against the U.S. government's tariffs imposed under the International Emergency Economic Powers Act (IEEPA), and is conducting a comprehensive assessment of its relevant content and impact.

The U.S. Supreme Court ruled on Friday that the U.S. government's imposition of tariffs on trading partners under the IEEPA is illegal.

While responding to media inquiries, a ministry spokesperson said that China has always opposed all forms of unilateral tariff hikes, emphasizing that there are no winners in a trade war and that protectionism leads to a dead end.

The unilateral measures of the U.S. side, such as the imposition of reciprocal tariffs and fentanyl tariffs, not only violate international economic and trade rules but also contravene domestic laws of the United States, and are not in the interests of any party, the spokesperson added.

"China urges the United States to lift the unilateral tariffs imposed on trading partners," the spokesperson said, stressing that when China and the United States cooperate, both benefit; and that when they fight, both suffer.

The spokesperson further stated that China has noted that the U.S. side is preparing to use alternative measures, such as trade investigations, in an attempt to maintain tariffs imposed on its trading partners. "China will closely monitor this and firmly safeguard its own interests." ■
