Callas opposed Putin's participation in the G20 summit in the United States The head of European diplomacy, Kaya Callas, spoke out against the participation of Russian President Vladimir Putin in the Group of Twenty (G20) summit in December in Florida. She said this in an interview with Bloomberg TV. According to her, the possible participation of Russian President Vladimir Putin in the G20 leaders' summit in Florida in December at the invitation of the United States could lead to the legalization of Russia's return to international forums. At the same time, Kalas opposed the normalization of relations with Russia. "The US invitation to this summit raises many serious questions," she noted.
