The two countries have agreed to a deal to jointly invest in Ukraine's mineral, raw materials and natural resource wealth in exchange for future U.S. aid.

The text of the agreement, made public by Ukraine’s government, made no mention of the security guarantees that Kyiv had long sought.

After months of tense negotiations, the U.S. and Ukraine have signed a deal that is expected to give Washington access to the country’s critical minerals and other natural resources.
