Turkey is not satisfied with Sweden's promises to resolve the issue with the Kurdish 'separatists' and is unlikely to withdraw its objections to the country's application for NATO membership unless the country takes more decisive steps, Turkey's ruling party spokesman Omer Celik said, Bloomberg reported.

Celik said these Swedish statements are good, but they are not enough until they are implemented.

Turkish President Recep Tayyip Erdogan has demanded that Sweden and Finland extradite suspects whom Turkey considers terrorists.

Celik's remarks, made ahead of a visit by NATO Secretary-General Jens Stoltenberg this week and a separate trip by new Swedish Prime Minister Ulf Kristersson, signaled that Turkey still has no intention of ratifying the membership applications, which it first threatened to veto in May.

The Swedish leader said convincing Turkey was not easy.

Stoltenberg urged Sweden and Finland to accommodate requests from Turkey, which has the second-largest military force in the North Atlantic Treaty Organization after the United States. While the June agreement pushed the process forward, allowing 28 of the 30 alliance members to ratify Scandinavian accession, Turkey and Hungary remain on the sidelines.

Erdogan is scheduled to meet with Stoltenberg in Istanbul on Friday to discuss NATO expansion as well as the war in Ukraine.

The Turkish leader is expected to receive Sweden's Kristersson in Ankara on Nov. 8.

Kristersson has repeatedly said his country will abide by the agreement with Turkey and cooperate in the fight against terrorism.

Erdogan faces elections next year and is seeking to consolidate support for the nationalists by pressuring Scandinavian countries to make written commitments to crack down not only on PKK supporters but also on its units, such as the YPG in Syria.

With the support of Western countries, the YPG played a significant role in defeating the Islamic State jihadists in Syria.
