Top officials from the Trump administration will meet with their Chinese counterparts in Sweden this week for their third formal round of economic talks since President Trump raised tariffs on Chinese imports to triple-digit levels this year. The primary goal is to extend a fragile trade truce that has prevented a devastating clash between the world’s largest economies.

The discussions are scheduled for Monday and Tuesday in Stockholm. Treasury Secretary Scott Bessent and Jamieson Greer, the United States trade representative, are leading the U.S. delegation. He Lifeng, the vice premier for economic policy, has been leading the talks on behalf of China.

The negotiations come during a pivotal week for the global economy, which has been gripped by uncertainty as a result of Mr. Trump’s chaotic trade agenda. The Trump administration has been trying to win concessions from many countries before an Aug. 1 deadline for reimposing tariffs announced in April. Those levies were suspended in order to reach trade deals.

Over the last week, the Trump administration has announced deals with some of America’s biggest trading partners in quick succession.

Last Tuesday, the United States and Japan finally agreed to a deal that included a 15 percent tariff on Japanese imports and a pledge from Japan to invest $550 billion in the United States.

On Sunday, Mr. Trump announced that he had also reached a deal with the European Union, a 27-nation bloc whose economies rely on exports to the United States. The deal would put a 15 percent tariff on many European exports, including cars.
