The United States is one step closer to opening its embassy in Kyiv after its top diplomat to Ukraine visited the country on Sunday.

Kristina Kvien and her team returned to Ukraine’s capital for the first time since Russia’s invasion began in February. The trip, timed to sync up with Victory in Europe Day, sought to reaffirm a pledge Secretary of State Antony Blinken made last month to reopen the U.S. Embassy in Ukraine.
