Poland will use its good relations with Ankara to convince Turkish President Recep Tayyip Erdogan to finally approve Sweden’s NATO membership, Prime Minister Mateusz Morawiecki said during a visit to Stockholm.

Morawiecki met with his counterpart Ulf Kristerson in Stockholm, expressing his support for Sweden and Finland’s NATO membership applications, insisting the alliance needs “new, strong allies”.

Speaking about Turkey, which recently strongly opposed Sweden’s NATO membership, Morawiecki said that Poland “will use its own good relations with Turkish partners to convince them for the fastest possible and preferably simultaneous membership of Sweden and of Finland in NATO”.

The accession of Sweden and Finland to NATO “it really changes the game” for the alliance, and is a “revolution for the global security architecture,” he added.

Negotiations between Sweden and Turkey over Stockholm’s NATO candidacy stalled after Danish-Swedish activist Rasmus Palundan burned the Koran during a protest near the Turkish embassy last month. The incident followed a series of anti-Sweden protests in Muslim countries.

However, the issues were already present as Ankara demanded the extradition of Turkish citizens whom it accuses of involvement in the 2016 coup attempt. With this, Stockholm has been reluctant to comply.

Although he has firmly ruled out for now ratifying Sweden’s application for NATO membership, Erdogan recently said he was ready to face the Finnish case separately and perhaps admit the country to the North Atlantic Alliance faster than its neighbor.

Finland, for its part, says it will stick to its original plan and join NATO along with Sweden, even if it takes more time. Nevertheless, its president, Sauli Niinisto, is confident that both countries will join NATO at the Vilnius summit in July.

During the joint press conference with Morawiecki, Christerson expressed his satisfaction that Poland was among the first NATO states to ratify Sweden’s membership and thanked him for his intention to discuss the issues with Erdogan .

Turkey and Hungary remain the only two of NATO’s 30 member states that have yet to ratify the accession of Finland and Sweden.
