Britain has opened discussions with European allies about releasing emergency diesel reserves following Donald Trump's threat to restrict US fuel exports, The Guardian reports.

British ministers conducted calls Thursday with officials from the European Commission, Germany, France, Italy and Ireland to explore whether drawing down reserves would be advisable. The Trump administration has already pressed Germany and France to release their stockpiles to help address rising global energy prices, warning of a US export ban if they refuse.

The talks reflect mounting concern across Europe over potential supply disruptions and price volatility. Britain, despite leaving the European Union, maintains coordination with key Continental partners on energy security matters. The timing suggests Westminster views the risk of US supply cuts as serious enough to warrant emergency stockpile discussions across multiple capitals.

No details have been released about the outcome of Thursday's ministerial calls or whether any agreement has been reached on triggering the release of reserves. The negotiations occur as global diesel markets face pressure from geopolitical tensions and energy supply concerns.
