Finland became NATO’s newest member today (4 April 2023), upon depositing its instrument of accession to the North Atlantic Treaty with the United States at NATO Headquarters in Brussels. NATO Allies signed Finland’s Accession Protocol on 5 July 2022, after which all 30 national parliaments voted to ratify the country’s membership.
“We welcome Finland to the Alliance!,” said NATO Secretary General Jens Stoltenberg, as Finnish Foreign Minister Pekka Haavisto deposited Finland’s instrument of accession with the government of the United States, represented by Secretary of State Antony Blinken. The Secretary General then welcomed Finnish President Sauli Niinistö to NATO Headquarters for a flag-raising ceremony to mark the country’s accession to the Alliance.
Speaking ahead of the ceremony, the Secretary General thanked President Niinistö for his outstanding leadership and for leading Finland into the most successful Alliance in history. “I am deeply proud to welcome Finland as a full-fledged member of our Alliance and I look forward to also welcoming Sweden as soon as possible,” he said. “Joining NATO is good for Finland, it is good for Nordic security and it is good for NATO as a whole,” he added. The Secretary General also noted that Finland’s accession shows the world that President Putin failed to “slam NATO’s door shut.” “Instead of less NATO, he has achieved the opposite; more NATO and our door remains firmly open,” he said.
The Finnish national anthem and the NATO hymn were played, as Finland’s flag was raised outside NATO Headquarters for the first time, in the presence of President Niinistö, Foreign Minister Haavisto, Defence Minister Kaikkonen, the foreign ministers of all NATO Allies and invitee Sweden. Simultaneous flag-raising ceremonies took place at Allied Command Operations (SHAPE) in Mons (Belgium) and Allied Command Transformation in Norfolk, Virginia (United States). Standing alongside President Niinistö, the Secretary General said: “Finland is safer and NATO is stronger with Finland as an Ally. Your forces are substantial and highly capable, your resilience is second to none and for many years troops from Finland and NATO countries have worked side-by-side as partners. From today, we stand together as Allies.”
