Latest: China vows to fight US 'at any cost' as trade spat worsens

Update 8.30: China has vowed to fight the US "at any cost" after President Donald Trump proposed slapping an additional $100bn (€81bn) in tariffs on Chinese goods in an escalating trade dispute between the world's two largest economies.

Mr Trump's surprise move to instruct the US Trade Representative to consider the additional tariffs came a day after Beijing announced plans to tax $50bn (€40bn) in American products, including soybeans and small aircraft, in response to a US move this week to add tariffs on $50bn (€40bn) in Chinese imports.
