The Finance Ministry said it would impose additional tariffs of 34% on all US goods from April 10.
Beijing also announced controls on exports of medium and heavy rare-earths, including samarium, gadolinium, terbium, dysprosium, lutetium, scandium and yttrium to the United States, effective April 4.
“The purpose of the Chinese government’s implementation of export controls on relevant items in accordance with the law is to better safeguard national security and interests, and to fulfill international obligations such as non-proliferation,” the Commerce Ministry said in a statement.
It also added 11 entities to the “unreliable entity” list, which allows Beijing to take punitive actions against foreign entities.
The tariffs have fed expectations for a global economic downturn and sharp price hikes across sectors in the world’s biggest consumer market.
