China's foreign ministry and commerce ministry both expressed strong opposition to the U.S. tariffs on China. China firmly deplores and opposes the U.S.

 decision to impose a 10-percent additional tariff on imports from China and will take necessary countermeasures to defend its legitimate rights and interests, 

a Chinese foreign ministry spokesperson said on Sunday.

U.S. President Donald Trump signed an executive order on Saturday to impose a 25-percent additional tariff on imports from Canada and Mexico and a 10-percent tariff hike on imports from China. 

Trump on Saturday ordered 25% tariffs on Canadian and Mexican imports and 10% on goods from China, saying Beijing needed to stanch the flow of fentanyl, a deadly opioid, into the United States. 

According to the spokesperson, China is one of the world's toughest countries on counter narcotics both in terms of policy and its implementation. Fentanyl is an

 issue for the United States. In the spirit of humanity and goodwill, China has given support to the United States in its response to this issue.

China's foreign ministry and commerce ministry both expressed strong opposition to the U.S. tariffs on China.

China firmly deplores and opposes the U.S. decision to impose a 10-percent additional tariff on imports from China and will take necessary countermeasures 

to defend its legitimate rights and interests, a Chinese foreign ministry spokesperson said on Sunday.

"China's position is firm and consistent. There is no winner in trade and tariff wars," the spokesperson stressed, adding that the U.S. unilateral tariff hikes 

severely violate World Trade Organization (WTO) rules. This move cannot solve the U.S. problems at home, and more importantly, does not benefit either side, 

still less the world.

China is strongly dissatisfied with and firmly opposes the U.S. tariffs on China. In response to the erroneous action by the United States, China will file a 

complaint at the WTO and take corresponding countermeasures to firmly safeguard its rights and interests, the Chinese Ministry of Commerce said in a statement

 on Sunday.

China urges the U.S. side to view and address its fentanyl and related issues objectively and rationally, rather than frequently use tariffs to threaten other 

countries, according to the statement.
