United States and Ukraine Weigh Mineral Deal
When U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy met to sign a minerals agreement on 28 February, their discussion devolved into a heated, and widely covered, exchange. The minerals agreement, if signed, would result in half of Ukraine’ future revenue from minerals and natural resources going to the United States, in exchange for U.S. military support.
