China on Monday warned other countries against making trade deals with the United States to China’s detriment.Governments including those of Taiwan, Japan and South Korea have begun negotiations with Washington after President Donald Trump announced sweeping tariffs against almost all of America’s trading partners on April 2.

Beijing said deals to restrict trade with China in exchange for U.S. tariff relief are “bargaining with a tiger for its skin” — seeking the impossible from the unreliable.

China is a far bigger trading partner than the US for most countries. That limits what Trump can demand, experts say.
