Neutral summary

The United States, Denmark and Greenland have signed a trilateral security agreement for Greenland. The signing ceremony took place on Tuesday, September 22, in New York on the sidelines of the 81st session of the UN General Assembly. The document was signed by US President Donald Trump, Danish Prime Minister Mette Frederiksen and Greenland's Prime Minister Jens-Frederik Nielsen. The agreement provides for the immediate start of a significant build-up of the US military presence on the island, including the construction of two major military bases. According to the White House, the document also bans the deployment of military facilities of any non-NATO countries on the island and allows the US to modernize the Pituffik Space Base in northwestern Greenland. At the same time, according to the published text, the creation of additional bases is only possible with the mutual consent of the parties. US Secretary of State Marco Rubio said the US military presence in Greenland would become the first line of US missile defense, since any potential missile attack on US territory would come over the Arctic. Trump, speaking at the UN General Assembly, said the agreement would “forever close” the island to US military rivals. El País notes that the agreement preserves the sovereignty and territorial integrity of the Kingdom of Denmark. Norwegian Prime Minister Jonas Gahr Støre, commenting on the deal, said the agreement between Denmark and the US is “a very good signal,” but called the rest of Trump's speech “quite dark.” According to CNBC, shares of US-listed Greenland companies surged after the announcement of the deal.
