MOSCOW, July 03. /ITAR-TASS/. Russia's Foreign Minister Sergei Lavrov has said Western partners should play a decisive role in implementing the Berlin agreements on Ukraine.

"The Western partners should persuade the authorities in Kiev to comply with the Berlin declaration to convene a contact group for coordinating ceasefire on the bilateral basis," Lavrov told ITAR-TASS on Thursday.

The foreign ministers of Russia, Germany, France and Ukraine met in Berlin on July 2 to discuss de-escalation in Ukraine. The ministers agreed a declaration on the resolution of the conflict in Ukraine's southeast.

Lavrov expressed hope that the international contact group on Ukraine would be able to meet shortly and welcomed the intention of Germany, France and Ukraine to support the decision of the Standing Committee of the Organization for Security and Cooperation in Europe (OSCE) to send observers to the Russian crossing points on the border with Ukraine.
