Trump's new tariff threat are of fresh tariffs which come in addition to the previous 10 per cent one levied on February 4.

U.S. President Donald Trump on Thursday said his proposed 25% tariffs on Mexican and Canadian goods will take effect on March 4 along with an extra 10% duty on Chinese imports because deadly drugs are still pouring into the U.

Trump imposes new tariffs on Mexico, Canada, and China, citing the ongoing fentanyl crisis and insufficient progress on curbing drug flows.

Beijing has less than a week to publish countermeasures as US administration takes a harder stance on its rival, despite backing down on 60% tariff threat after Trump took office.

Beijing accused the United States on Friday of exerting "tariff pressure and blackmail" after President Donald Trump's latest threat to slap an extra duty of 10% on imports from China, citing a continued flow of fentanyl into the country.

China's Ministry of Foreign Affairs has criticized the U.S. for using the fentanyl issue as a pretext to threaten China. Ministry spokesperson Lin Jian also noted that there are no winners in trade and tariff wars.

China’s officials condemned President Trump for his decision to add a 10 percent tariff on Chinese imports over the country’s alleged complicity in the international smuggling of fentanyl, a deadly synthetic drug.
