Turkish President Recep Tayyip Erdoğan, who in the past has been called a “dear friend” by Vladimir Putin, dealt a blow to the Russian leader when he advocated the return of annexed Crimea to Ukraine.
“Our support for Ukraine’s territorial integrity, sovereignty and independence is unwavering,” Erdoğan said in a video message to the Fourth Crimea Platform Leaders Summit on Wednesday, Turkey’s state-run Anadolu Agency reported. “The return of Crimea to Ukraine is a requirement of international law.”
Turkey, a NATO nation since 1952, has maintained cordial relations with Russia throughout Putin’s full-scale invasion of Ukraine, opposing Western sanctions placed on the country. At the same time, Ankara has sent Kyiv armed drones and condemned Russia’s decision to invade its neighbor.
