U.S. and Chinese officials concluded the first day of talks in Madrid on Sunday, where they are set to discuss their strained trade ties, a looming divestiture deadline for Chinese short-video app TikTok, as well as Washington's demands that its allies place tariffs on imports from China over its purchases of Russian oil.

U.S. Treasury Secretary Scott Bessent told reporters as he left the central government palace: "We’ll start again in the morning."

Talks between delegations led by Bessent and U.S. Trade Representative Jamieson Greer with Chinese Vice Premier He Lifeng and China's top trade negotiator, Li Chenggang, at the baroque Palacio de Santa Cruz, which houses Spain's foreign ministry ended after about six hours.
