The rally in U.S. stocks came to a halt on Thursday on new concerns that the U.S.-Chinese trade dispute will intensify. Stock markets and major government bond yields have risen in recent weeks on hopes that a global trade war could be averted, particularly as leaders of the United States and Canada expressed optimism they could reach a new North American Free Trade Agreement by Friday.

President Donald Trump has told aides he is ready to impose tariffs on $200 billion more in Chinese imports as soon as a public comment period on the plan ends next week, Bloomberg News reported.
