Punishing 25% levies on imports from America’s closest neighbors were due to come into force at 12:01 a.m. ET Tuesday, but Trump put his two-front trade war on hold, claiming he’d scored two big wins and major concessions.

U.S. President Donald Trump said on Tuesday he is in no hurry to speak to Chinese President Xi Jinping to try to defuse a new trade war between the world's two largest economies sparked by his sweeping 10% tariffs on all Chinese imports.
