“Diplomats are returning to Ukraine this week to begin the process of opening an embassy in Kyiv.

My predictions: they will start in Lvov, in western Ukraine, with the goal of opening an embassy as soon as possible, but also as safely as possible, ”RIA Novosti quoted him as saying.

The US Secretary of State estimates that the process will take "the next few weeks."

Earlier, State Department spokesman Ned Price confirmed during a briefing that US embassy staff returned to Lviv on April 26.

In late February, the State Department urged non-critical American diplomats to leave Ukraine.
