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.
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, joining NATO is good for Finland, it is good for Nordic security and it is good for NATO as a whole,”NATO Secretary General Jens Stoltenberg
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. Simultaneous flag-raising ceremonies took place at NATO Allied Commands.
