Ukrainian Foreign Minister Pavlo Klimkin has said that Russia's aggression and its attempts to change the map of Europe will fail, just like the Molotov–Ribbentrop Pact.

"Today [August 23] is the anniversary of the Molotov–Ribbentrop Pact. That attempt to change the map of Europe with aggression didn't succeed. Just like that, Russia's aggression will fail as well," Klimkin wrote on his Twitter account on Sunday.

The Molotov–Ribbentrop Pact, named after the Soviet foreign minister Vyacheslav Molotov and the German foreign minister Joachim von Ribbentrop, officially called the Treaty of Non-aggression between Germany and the Union of Soviet Socialist Republics, was a non-aggression pact signed between Nazi Germany and the Soviet Union in Moscow on 23 August 1939. It is also known as the Ribbentrop–Molotov Pact or Nazi–Soviet Pact.

The pact remained in force until Germany broke it by invading the Soviet Union on 22 June 1941.
