Ukraine is ready to sign an agreement that would give the U.S. access to its valuable rare minerals in the hopes of ensuring continued American support for Kyiv in its grinding war with Russia, senior Ukrainian officials said Wednesday.

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.

U.S. officials say the coming week will be "very critical" for determining whether it remains involved in talks.
