BEIJING — China said on Monday that it will lower tariffs on a variety of goods imported from around the world starting on Jan. 1, moving to support domestic consumers even as a trade truce with the United States has relieved some of the pressure on the Chinese economy.

The action, less than two weeks after Beijing and the Trump administration reached a partial deal to end their trade war, also helps China buttress its assertions that it has continued to open up its market despite the long-running conflict with the United States.

The stopgap trade pact reached this month forestalled one last round of American tariffs that would have extended levies to cover nearly every shoe, laptop and toy that the United States imports from China.

But the deal still leaves many question marks over China’s economy, which has slowed as the tariff conflict has dragged on. With many tariffs on American products still in place, China needs to keep trading with other nations to satisfy its people’s demands for imported goods.
