On February 28, Ukrainian President Zelensky visited the White House in the United States and met with President Trump. The two sides had a fierce argument, and an agreement on Ukraine providing the United States with the right to exploit mineral resources was not signed. US media reported on March 3 that Trump had ordered a suspension of US military aid to Ukraine. Zelensky said on the 4th that he regretted what had happened during his meeting with Trump at the White House, and the Ukrainian side was willing to sign the US - Ukraine mineral agreement at any time and in any convenient way.
On March 5, US Central Intelligence Agency Director John Ratcliffe said that the United States had suspended sharing intelligence with Ukraine. This move was intended to pressure Zelensky to cooperate with Trump and hold peace talks with Russia. The Ukrainian side said on the same day that it planned to hold new talks with the US side.
