WASHINGTON, June 17 – The United States is actively cooperating with the European Union on new sanctions against Russia, U.S. Assistant Secretary of State Victoria Nuland said.

"We are well aligned now on what a next round of economic sanctions would look like, in addition to continuing to look for individuals who one would sanction," Nuland told a think tank in Washington.

The United States and the European Union "are now working on a series of sanctions in the energy sector, in the banking sector, in the defense sector," she said.
