China says U.S President Donald Trump’s latest tariff moves could harm the countries' trade relationship. Beijing's international trade representative said his government expressed serious concern during high-level talks in Paris. The meeting was meant to prepare for Trump's planned trip to China in about two weeks, though the U.S. president has warned that it could be delayed. The Iran war has emerged as a potential stumbling block just as the U.S. and China were patching up relations following a tariff war and truce. The U.S. treasury secretary says any postponement wouldn’t be to pressure China on that new issue.
