U.S. Secretary of State John Kerry has said that the Ukrainian crisis could potentially be resolved by cooperation.

There is a potential to try to make progress in Ukraine, if everyone cooperates, he said on MSNBC TV.

The U.S. will continue to try to solve the Ukrainian issue within the framework of the Minsk agreements, Kerry said.

He also stressed the importance of the upcoming meeting of 'Normandy Four' (Germany, France, Ukraine and Russia) which is scheduled to take place on October 2 in Paris.
