Last month, the USA imposed duties of 25 percent on Chinese imports worth $34bn.
Trump, who has boasted that trade wars are "easy to win", has threatened to ramp up the pressure and slap tariffs on virtually all of China's exports to the United States if Beijing does not back down and take steps to reduce the US$335 billion USA trade deficit with that country.

China's foreign trade maintained steady growth in the first seven months of this year despite escalating trade tensions with the United States, with data pointing to a more balanced trade picture. With higher oil prices this year and the taxes they now can't avoid paying, the teapots are expected to reduce their imports, threatening China's oil demand growth, and ultimately, global oil demand growth.

China has already retaliated against the United States with its own tariffs and proposed others if Washington goes ahead with all its threats. Products being targeted now include crude oil, cars, steel and medical equipment.
