President Recep Tayyip Erdogan and U.S. President Joe Biden met on the sidelines of the NATO summit held in Brussels to discuss disagreements. The parties agreed on the Afghanistan issue, where Turkey will secure the Kabul Airport with the necessary support of the Biden administration. The two leaders weren’t able to resolve the S-400 issue on which the dialogue will continue, according to the U.S. National Security Advisor Jake Sullivan. They also couldn’t find a common ground on the human rights issue. Erdogan said ‘Thank God’ regarding the events of 1915 which wasn’t discussed at the meeting. Erdogan also gathered with his French counterpart Emmanuel Macron, German Chancellor Angela Merkel, Greek Prime Minister Kyriakos Mitsotakis, the UK Prime Minister Boris Jonson during the NATO Summit to discuss bilateral and regional issues before he paid a visit to Azerbaijan where he and President Ilham Aliyev signed the Shusha Declaration to boost defense cooperation.
