The Trump administration is imposing tariffs on $US200 billion more in Chinese goods starting next week, escalating a trade war between the world's two biggest economies and raising prices on consumer goods ranging from handbags to bicycle tires.
The tariffs will start at 10 per cent and rise to 25 per cent starting January 1, 2019.
US President Donald Trump decided to begin taxing the imports - equal to nearly 40 per cent of goods China sold the United States last year - after a public comment period.
China has said it's ready to impose retaliatory tariffs on US goods.
The US had already imposed tariffs on $US50 billion in Chinese imports.
Trump initiated the fight to punish Beijing for what he says are China's predatory tactics to try to supplant US technological supremacy.
