Poland and Finland have reached an unprecedented level of cooperation in security, trade and technology, according to Poland’s outgoing ambassador to Helsinki, Tomasz Chłoń, who returns to Warsaw in autumn 2026.

The well-liked Head of Mission delivered his farewell speech at the Polish Armed Forces Day reception on Thursday, 17 September 2026, highlighting the transformation of Finnish-Polish relations since Finland joined NATO.

“Since 4 April 2023, Poland and Finland are no longer just good partners in the military sense, but allies in the most successful alliance in history,” Chłoń said, describing both countries as among Ukraine’s staunchest supporters.

Security has become the central issue in bilateral relations, he argued, while Finland’s NATO membership has fundamentally strengthened the alliance’s position in Northern Europe.

“We at NATO are overwhelmingly stronger than our opponent,” Chłoń said, pointing out that the ten member states of the Council of the Baltic Sea States have combined budgets approaching €300 billion, according to his figures.

Economic relations have also expanded considerably.

“Economically, we are as strong as ever. Our annual trade and services turnover with Finland is €7.6 billion,” Chłoń said.

Poland is now approaching the Netherlands in its ambition to become Finland’s fifth-largest trading partner.

The ambassador also highlighted the increasingly sophisticated technological cooperation between the two countries.

“I frequently say that our relations have reached cosmic and quantum levels,” he remarked, citing the Finnish-Polish satellite company ICEYE and the delivery of a Finnish quantum computer to Wrocław in Poland.

Political cooperation has become exceptionally close, particularly in European security and support for Ukraine.

“We see eye to eye on almost anything,” Chłoń said. He suggested that Polish Foreign Minister Radosław Sikorski could deliver a speech prepared for his Finnish counterpart, Elina Valtonen, with hardly any changes.

The two countries also cooperate closely within the European Union, NATO and Baltic Sea organisations. Chłoń highlighted Poland’s recent chairmanship of the Council of the Baltic Sea States and its assumption of the HELCOM chairmanship in July 2026, with the aim of making the Baltic Sea cleaner and safer.

He described relations between Finland and Poland as extending well beyond traditional diplomacy, encompassing regional cooperation, science, culture, business and increasingly close contacts between citizens.

“Our relations are no longer merely bilateral. They are also internal,” he said, referring to the depth of cooperation within the shared European and transatlantic institutions.

Concluding his assignment in Helsinki, Chłoń reflected on the different countries in which he had served during his diplomatic career.

“This Finnish life, and the Finns, shaped me,” he said. “Finland has been the best of times.”
