U.S. Secretary of State Rex Tillerson has said the Russian Federation must accelerate the implementation of its commitments under the Minsk Agreements.

"On Ukraine, the Secretary noted the upcoming meeting between U.S. Special Representative Volker and Russian Representative Surkov and emphasized the need for Russia to accelerate implementation of its commitments under the Minsk Agreements and reverse the recent escalation in the fighting in eastern Ukraine," spokesperson for the U.S. Department Heather Nauert said following the Secretary's phone conversation with Russian Foreign Minister Sergey Lavrov on Wednesday, January 24.

The U.S. Department of State also reports the parties discussed issues and concerns related to Syria and North Korea.

However, the website of the Russian Foreign Ministry, which also reports about the dialogue between Tillerson and Lavrov, does not mention among the topics the discussion of the situation in Ukraine.
