President-elect Donald Trump Tuesday threatened to place new tariffs on imports from Denmark unless the country gives up control of Greenland, news that dented the stocks of some of Denmark’s most important companies and underscored Trump’s focus on geopolitical competition.

Donald Trump also vows to change the Gulf of Mexico's name and repeats promises to impose tariffs on Canada and Mexico.
