The Kremlin said on Friday that there was a mutual understanding about the need for a meeting between U.S. President Donald Trump and Russian President Vladimir Putin, but that the details of such an encounter had yet to be worked out.

Zelensky rejected the US demand for a share of Ukraine's rare earth minerals on Wednesday, after Trump said he wanted a "deal" that would reflect the amount of aid provided to Ukraine from the US. Waltz said the White House was "very frustrated" with Zelensky after he levelled "unacceptable" insults at US President Donald Trump earlier this week.

U.S. President Donald Trump said Wednesday he expects to see his Russian counterpart Vladimir Putin in Saudi Arabia for their first meeting since the Republican took office. Trump made the remarks following an almost 90-minute phone conversation with Putin in which the two leaders discussed ending Moscow’s full-scale invasion of Ukraine.
