U.S. Secretary of State John Kerry following the meeting with EU High Representative Federica Mogherini has said there appear different views towards Russia sanctions.

"Right now there appear to be different views as to what the interpretation of the political requirements [to Russia] are. So we will be very engaged with the EU in working going forward with respect to the Minsk implementation," Kerry said.

"We have the challenges, of course, of Ukraine. And here the EU is again critical to the sanctions regime that is essential to helping to impress on Russia the need to fully implement the Minsk agreements," the Secretary stressed.

He has said there are some very important choices coming up in the next months regarding the continuation of the sanctions regime.
