President Donald Trump has managed to make his erratic trade policies even more baffling to countries desperate to negotiate an escape from his wrath.

President Trump escalates his trade war, imposing new tariffs on Mexico and the EU. The move raises concerns about rising consumer prices and economic uncertainty.

Trump insiders maintain that it would make little sense — politically or from a policy standpoint — for the president to offer any further extensions on trade.

Trump this week announced tariffs on other countries, including Japan, South Korea, Canada and Brazil, as well as a 50% tariff on copper.

Donald Trump has said he will impose 25 per cent tariffs on imports of goods from Japan and South Korea, in an announcement that sent US stocks sliding. The president on Monday said the new levies on both countries would come into effect on August 1. Trump has vowed to announce tariff rates for dozens of other trading partners in coming days.

Asian shares rose Tuesday after stocks on Wall Street closed broadly lower as the White House stepped up pressure on major trading partners to make deals before punishing tariffs imposed by the U.S. take effect.

South Korea will follow terms previously agreed with the United States on defence cost sharing, its foreign ministry said on Wednesday, following a call by U.S. President Donald Trump for Seoul to pay more for the U.

The president has already threatened an additional 10% tariff on goods from countries aligning themselves with a bloc of nations that includes China and Russia.
