The Turkish president Recep Tayyip Erdogan received on Sunday NATO Secretary General Jens Stoltenberg in Istanbul for talks.

The Turkish presidency did not share any further information about the closed-door meeting at Dolmabahçe Palace, but it is believed that the NATO Secretary-General raised the issue of Sweden’s NATO membership with the Turkish president.

On Saturday, Stoltenberg attended Erdogan’s swearing-in ceremony.

Finland and Sweden applied to join NATO soon after Russia invaded Ukraine in February 2022.

Although Turkey approved Finland’s NATO membership, it “expects Sweden to comply with a tripartite memorandum signed last June in Madrid to address Ankara’s security concerns.”

Sweden has voted an anti-terror law last November, hoping that Ankara would approve its accession to NATO. The new law, effective June 1, allows authorities to prosecute people who support terrorist groups.

Alliance foreign ministers hope Turkey will approve Sweden’s membership before the NATO summit in Vilnius on July 11-12.
