A minerals deal between Ukraine and the United States could finally be signed as early as Wednesday after weeks of intense negotiations that at times turned bitter and temporarily derailed Washington’s aid to Ukraine.

The U.S. and Ukraine signed a deal Wednesday for access to Ukrainian mineral wealth, overcoming last-minute haggling that had held up the agreement. Treasury Secretary Scott Bessant hailed the deal as a step toward a negotiated end to the war in Ukraine and a beginning of the country’s reconstruction.
