The outgoing prime minister of Greenland on Thursday said he would summon party leaders to strengthen their rejection of US President Donald Trump’s plan to annex the island territory, following his most recent comments on the issue.

Greenland’s leaders issued a sharp rebuke of Donald Trump’s renewed calls to annex it Thursday, after the president once again expressed his desire to take over the Arctic island.

Donald Trump repeated on Thursday that the United States will annex Greenland, while cheering the Arctic island’s election result. “I think it will happen,” said the U.S. president, when asked about his vision for the potential annexation of Greenland during an Oval Office meeting with NATO Secretary-General Mark Rutte.
