Ukraine managed to wrangle some more favorable terms out of the United States before signing the long-awaited minerals deal on Wednesday.

Seven months later, a landmark deal between Ukraine and the Trump administration on Ukraine’s mineral resources was inked. But the road in between was paved with mutual recriminations, a historic Oval Office blowout, “hundreds” of revisions, and finally, a chance meeting on the sidelines of Pope Francis’ funeral.

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.
