The Commerce Ministry in Beijing also said it would increase the export controls on key rare earth materials that are essential for high-tech industries that produce chips and electric vehicle batteries. It also announced export controls for 27 US companies.
On top of the retaliatory measures, the ministry said it was filing a lawsuit with the World Trade Organization (WTO).
"The United States' imposition of so-called 'reciprocal tariffs' seriously violates WTO rules, seriously damages the legitimate rights and interests of WTO members, and seriously undermines the rules-based multilateral trading system and international economic and trade order," the Commerce Ministry said.
"It is a typical unilateral bullying practice that endangers the stability of the global economic and trade order. China firmly opposes this," it added.
Do Trump's new tariffs violate WTO regulations?
