China warns US against expanding tech restrictions, vows resolute retaliation

The United States, Denmark and Greenland have reached a landmark agreement that opens the way for the US to have a long-term security role in Greenland. Kobsak Pootrakool, Senior Executive Vice President of Bangkok Bank, or BBL, posted on Facebook under the name Kobsak Pootrakool, stating that Denmark and Greenland have granted the US the rights to use Greenland as the US wants, to serve as a key strategic point for building the Golden Dome and for controlling shipping through the emerging Arctic route. President Trump announced that this agreement gives the US permanent control over security and all other necessary matters in Greenland, at no cost to the US, and that countries hostile to the US will not be able to establish military bases, station troops, or invest in sensitive businesses in Greenland without explicit written approval from the US. Kobsak stated that this agreement is eternal, with no end date, and that the US will immediately begin the process of establishing a large military force in suitable areas of Greenland. He also viewed this as significant progress within the framework of the Donroe Doctrine, under which the US seeks to control key points around its neighborhood in North and South America, following Panama, Venezuela, Colombia and Greenland, with Cuba and Brazil remaining, awaiting the October 4 election.
