The Commerce Ministry on Friday said it opposed US President Donald Trump's latest threat to impose an additional 10 percent tariff on Chinese imports and vowed to take "all necessary countermeasures" if Chinese entities got caught up in the levies.

In a statement, the ministry accused the US of "shifting the blame" on fentanyl flows into the United States and urged Washington to "return to the right track of properly resolving differences through dialogue on an equal footing as soon as possible."

It added China had some of the world's strictest anti-drug policies and highlighted the risks new tariffs would bring to global supply chains.

Trump said on Thursday his proposed 25 percent tariffs on Mexican and Canadian goods would take effect on Tuesday, along with the additional 10 percent levy on Chinese imports on top of an existing levy of the same rate imposed on China earlier this month. (Agencies)
