As President Donald Trump unleashes sweeping changes across the US government and slaps tariffs on America’s leading trade partners, Chinese leader Xi Jinping is preparing to hold a major political gathering designed to project something else: confidence in his country’s ability to weather external headwinds.

U.S. President Donald Trump's new 25% tariffs on imports from Mexico and Canada took effect on Tuesday, along with a doubling of duties on Chinese goods to 20%, launching new trade conflicts with the top three U.

China on Tuesday swiftly retaliated against fresh U.S. tariffs, announcing 10%-15% hikes to import levies covering a range of American agricultural and food products, moving the world's top two economies a step closer toward an all-out trade war.
