The US plans to impose tariffs on up to $60bn (£42.5bn) in Chinese imports and limit the country’s investment in the US in retaliation for years of alleged intellectual property theft.
The White House said the actions were necessary to counter unfair competition from China’s state-led economy.
It said years of talks had failed to produce change. China said it was ready to retaliate with “necessary measures”.
Beijing also said it would “fight to the end” in any trade war with the US.
Everything but tech support.
