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.

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

After ongoing deliberations and uncertainty, the United States and Ukraine signed a deal on Wednesday, April 30, allowing the U.S. preferential access to new Ukrainian minerals deals in return for an investment fund for Kyiv.
