Finnish President Alexander Stubb made a surprise trip on Saturday to meet US President Donald Trump at his estate in Florida, where the two leaders discussed strengthening their countries’ bilateral partnership and played a round of golf. “President Stubb and I look forward to strengthening the partnership between the United States and Finland, and that includes the purchase and development of a large number of badly needed Icebreakers for the US, delivering Peace and International Security for our Countries, and the World,” Trump said in a social media post. The two presidents met for breakfast, played golf and had lunch together. They also discussed foreign policy issues, including Ukraine. Ukrainian President Volodymyr Zelensky met with Stubb in Helsinki last week. The Finnish president’s office said in a statement that Stubb’s unannounced visit to Trump’s Mar-a-Lago estate in West Palm Beach, Florida, was informal. The meeting took place a day after Trump’s US vice-president, J.D. Vance, made an uninvited visit to Greenland, a semi-autonomous territory of Finland’s close Nordic ally Denmark. Vance accused Denmark of doing a poor job keeping Greenland safe. Trump has expressed interest in acquiring Greenland, part of a growing international focus on competition to control the Arctic. Denmark’s government opposes such a move, as do most Greenland residents. Finland is the world’s leading producer of icebreakers. About 80 per cent of the ships have been designed by Finnish companies, and around 60 per cent of them have been built at Finnish shipyards. In November, Canada, Finland and the administration of former US president Joe Biden signed a deal called the Icebreaker Collaboration Effort (ICE) to work “together to develop world-class Arctic and polar icebreakers through the exchange of knowledge, information, and resources”. Before his visit, Stubb had said he hoped to play golf with Trump and that icebreaker diplomacy could help Finland maintain good relations with the US and Trump. Finland shares the European Union’s longest border with Russia. After Russia invaded Ukraine, the country made a foreign policy U-turn after decades of military non-alignment, deciding to join Nato together with Sweden. Trump’s frequent criticism of Nato allies and his shift toward normalising relations with Russia have some European countries scrambling to boost their own defence spending.
