KYIV, Ukraine (AP) — Ukraine is prepared to sign a landmark mineral resources agreement with the United States in Washington on Wednesday, according to two senior Ukrainian officials who spoke on condition of anonymity because they weren’t authorized to discuss the matter publicly.

Donald Trump is “confident” a deal on critical minerals will be signed with Ukraine, the White House said, a move that could bolster US support for Kyiv as the US president grows frustrated over delays in clinching a ceasefire in Russia’s war on Ukraine.
