The Business Rules the Trump Administration Is Racing to Finish

Mr. Trump signed an executive order on Tuesday banning transactions with eight Chinese software applications, including Alipay. It was the latest escalation of the president's economic war with China. Details and the start of the ban will fall to Mr. Biden, who could decide not to follow through on the idea. Separately, the Trump administration has also banned the import of some cotton from the Xinjiang region, where China has detained vast numbers of people who are members of ethnic minorities and forced them to work in fields and factories. In another move, the administration prohibited several Chinese companies, including the chip maker SMIC and the drone maker DJI, from buying American products.
