The Treaty of Friendship, Cooperation and Partnership between the Russian Federation and Ukraine, or the “Big Treaty”, was signed in Kiev on May 31, 1997 by the presidents of Russia and Ukraine, Boris Yeltsin and Leonid Kuchma. The document came into force on April 1, 1999.

On December 10, Ukrainian President Petro Poroshenko signed the law on the termination of the treaty of friendship with Russia.

The Russian Foreign Ministry called the decision of Kiev to terminate the friendship agreement a mistake.

First Deputy Chairman of the Committee on Foreign Affairs of the Federation Council Vladimir Dzhabarov, in an interview with the publication PolitEkspert, assessed this situation.
