China will buy Greenland slowly. They already offered to buy the closed USAF Sondrestram Airbase, but Denmark refused. China will eventually get a port for “research”, even if they have to build it. China recently offered to build three airports in Greenland.
What I would like to know is what the residents of Greenland want? Do they want to be Chinese citizens or American? There is an island on the other side of the world where the people desperately wish to be American and not Chinese!
