On September 18, local time, US President Trump posted on social media that the US has reached an agreement with Denmark and its autonomous territory Greenland to obtain “permanent control” over Greenland's security and all other related matters, and the US side will not have to pay for this. Trump said that this is an indefinite agreement to ensure that the US always has full power to take necessary actions in Greenland and guarantee the safety of Greenland and America itself. Without written permission from the US side, hostile forces of the US side are prohibited from establishing military bases, maintaining military presence, or making sensitive investments in Greenland. Trump also said that the US side will establish a large-scale military presence in an appropriate area of Greenland and cooperate with local people to carry out related development and construction.
