Chinese media have mocked US President Donald Trump over plans to impose 25% tariffs on $50bn worth of Chinese goods, saying "wise men build bridges but fools build walls".
China retaliated, saying it would impose an additional 25% tariff on 659 US goods worth $50bn.
The US had earlier warned that it will impose even more tariffs should China retaliate.
Mr Trump said the tariffs were "essential to preventing further unfair transfers of American technology and intellectual property to China, which will protect American jobs.".
