STOCKHOLM (AP) – Sweden on Tuesday signed a formal request to join NATO, a day after the country announced it would seek membership in the 30-member military alliance. In neighboring Finland, lawmakers are expected later in the day to formally endorse Finnish leaders´ decision also to join.

The moves by the two Nordic countries, ending Sweden´s more than 200 years of military nonalignment and Finland´s nonalignment after World War II, have provoked the ire of the Kremlin.

While most NATO members are keen to welcome the two countries as quickly as possible, Turkey has potentially complicated their accession by saying it cannot allow them to become members because of their perceived inaction against exiled Kurdish militants.

Turkish President Recep Tayyip Erdogan on Monday doubled down on comments last week indicating that the two Nordic countries´ path to NATO would be anything but smooth. All 30 current NATO countries must agree to open the door to new members. He accused the two Nordic countries of refusing to extradite “terrorists” wanted by his country.

“It feels like we have taken a decision that is the best for Sweden,” she said while signing the document.

Finnish President Sauli Niinisto arrived in Sweden for an official two-day visit and was welcomed by Sweden´s King Carl XVI Gustaf and Queen Silvia, who had invited him. Niinisto addressed Sweden’s Parliament and said, “we took peace for granted; on Feb. 24 the peace was broken,” in a reference to the date that Ukraine was invaded by Russia.

“Our old ways of handling things no longer correspond to the new situation,” Niinisto told Swedish lawmakers.” Our relations with Russia have changed.”

He also spoke about Erdogan’s comments, saying they were “surprising and interesting.”

“Turkey´s statements have changed and toughened very quickly in recent days, but I am sure that we will resolve the situation with the help of constructive talks,” Niinisto said.

He is later to meet Swedish Prime Minister Magdalena Andersson.

On Twitter, Niinisto said that “the timing is excellent, a strong and stable Nordic region is our common cause.”

During a brief press conference, Carl XVI Gustaf said “the visit is characterized by the serious situation in our vicinity.” Niinisto added that “our security policy line has long been similar and even now, when the situation demands it, we take our steps together.”
