U.S. Ambassador to Ukraine Marie Yovanovitch said, Censor.NET reports referring to Radio Svoboda.
At present, the United States is unlikely to ponder joining the Normandy format, according to the diplomat.
Yovanovitch said it does not mean that Washington will not act at the diplomatic level and added the U.S. continues the cooperation with Ukraine, consultations with France and Germany, and regular meetings with Russians.
This is how the U.S. is involved in the Normandy process, the ambassador said.
