Presidents Donald Trump and Xi Jinping have no shortage of difficult issues to cover when they sit down for talks on Thursday at the White House.

President Donald Trump on Tuesday signed an agreement with Denmark and Greenland aimed at strengthening Arctic and North Atlantic security, paving the way for more U.S. bases in Greenland and easing tensions over his repeated calls for the vast island to become part of the United States.

The signing on the sidelines of the U.N. General Assembly in New York comes days after Trump announced the deal to bolster the U.S. military presence on Greenland but keep it under Danish control. The agreement would still apply if Greenland eventually chooses independence.
