Donald Trump green-lights mass tariff rollout against China, Mexico and Canada in TRIPLE executive order

Donald Trump has signed three executive orders green-lighting trade tariffs against China, Mexico and Canada.

The tariffs are worth up to 25 per cent on all imports to the US - and could be just the start of a trade war with America's biggest importers.

A White House official said on Saturday that the executive orders would also contain "retaliation clauses", so that if a country tried to retaliate with tariffs on US products, it would face further tariff hikes in return.
