The US is open to recognising the annexed Crimea peninsula as Russian territory as part of a wider Ukraine peace deal.
On Thursday, Steve Witkoff, the US special envoy, presented allies with proposals in Paris that would freeze current battle lines and leave most Russian-occupied Ukrainian territory under Moscow’s control.
The potential concession comes as Donald Trump, the US president, signalled on Friday that his administration would abandon peace-brokering efforts without quick progress.
