Trade war fears reignite as EU strikes back at Donald Trump's threat

Fears of a US-EU trade war have been reignited after Europe refused to back down in the face of fresh threats from Donald Trump.

The word tariff has dominated much of the US president's second term, and he has repeatedly and freely threatened countries with them.

On Friday, after a period of relative calm which has included striking a deal with the UK, he threatened to impose a 50% tariff on the EU after claiming trade talks with Brussels were "going nowhere". The US president has repeatedly taken issue with the EU, going as far as to claim it was created to rip the US off.

However, in the face of the latest hostile rhetoric from Mr Trump's social media account, the European Commission - which oversees trade for the 27-country bloc - has refused to back down. EU trade chief Maros Sefcovic said: "EU-US trade is unmatched and must be guided by mutual respect, not threats.

"We stand ready to defend our interests." Fellow EU leaders and ministers have also held the line after Mr Trump's comments. Polish deputy economy minister Michal Baranowski said the tariffs appeared to be a negotiating ploy, with Dutch prime minister Dick Schoof said tariffs "can go up and down".

French trade minister Laurent Saint-Martin said the latest threats did nothing to help trade talks. He stressed "de-escalation" was one of the EU's main aims but warned: "We are ready to respond." Mr Sefcovic spoke with US trade representative Jamieson Greer and commerce secretary Howard Lutnick after Mr Trump's comments.

Mr Trump has previously backed down on a tit-for-tat trade war with China, which saw tariffs soar above 100%. Read more:Trump accepts $400m plane from QatarJudge blocks Trump's Harvard foreign student ban Sticking points Talks between the US and EU have stumbled.

In the past week, Washington sent a list of demands to Brussels - including adopting US food safety standards and removing national digital services taxes, people familiar with the talks told Reuters news agency. In response, the EU reportedly offered a mutually beneficial deal that could include the bloc potentially buying more liquefied natural gas and soybeans from the US, as well as cooperation on issues such as steel overcapacity, which both sides blame on China.

Stocks tumble as Trump grumbles Major stock indices tumbled after Mr Trump's comments, which came as he also threatened to slap US tech giant Apple with a 25% tariff. The president is adamant that he wants the company's iPhones to be built in America.

The vast majority of its phones are made in China, and the company has also shifted some production to India. Shares of Apple ended 3% lower and the dollar sank 1% versus the Japanese yen and the euro rose 0.8% against the dollar..
