"The European Union has lost Russia. But it's his own fault. After all, it is the EU member states and the leaders of the Union itself who openly declare the need to inflict a strategic defeat on Russia, as they say," he said in an interview with the Argumenty i Fakty website.

Lavrov recalled that European countries supply Kiev with weapons and ammunition, as well as send instructors and mercenaries to Ukraine.

"For these reasons, we consider the EU as an unfriendly association," the minister explained.

Earlier, the head of European diplomacy, Josep Borrell, repeated behind the Ukrainian media a sarcastic April Fool's joke about the beginning of Russia's presidency in the UN Security Council.

Deputy Chairman of the Russian Security Council Dmitry Medvedev said that on the occasion of April Fool's Day, Borrell is a great specialist - this is his day.
