BEIJING—China said it would slash tariffs on $75 billion of U.S. imports in half as part of its efforts to implement a recently signed trade agreement with Washington.

Beginning Feb. 14, China will cut tariffs on some U.S. goods to 5% from 10%, while levies on some other items will be reduced to 2.5% from 5%, China’s Ministry of Finance said Thursday. The tariffs were imposed in September and December during a brutal trade fight between the world’s two largest economies.

The U.S. has already laid out plans to reduce the tariff rate on certain imports from China that have been penalized in the trade war, although most tariffs will remain. Starting Feb. 14, the U.S. will lower tariffs on roughly $120 billion in Chinese goods—including electronics and apparel—to 7.5%, from 15% currently, the U.S. trade representative’s office said on Jan. 22. That also fulfills a pledge made under the U.S.-China trade agreement signed Jan. 15.

The tariff cuts come amid growing doubts about Beijing’s ability to follow through on the phase-one trade deal, in which China has pledged to boost its purchases of American merchandise and services by $200 billion over two years.

A coronavirus outbreak that began in China in late January and has spread to more than a dozen countries has caused a near-standstill in economic activity in the country. Chinese authorities have placed many parts of the country on lockdown in an effort to contain the epidemic.
