The trade war between the US and China – which seemed to be nearing an end – has suddenly escalated with the threat of new tariffs.
US President Donald Trump vowed to more than double tariffs on $200bn (£153bn) of Chinese goods on Friday and to introduce fresh ones “shortly”.
Despite this, the Chinese are starting two days of negotiations with the US.
The US president’s threat to raise tariffs comes amid claims Beijing is trying to row back on a trade deal.
The world’s two largest economies have already imposed duties on billions of dollars worth of one another’s goods.
A further escalation in the trade dispute would create renewed uncertainty for businesses and consumers, hurting the world economy.
