The Kremlin said on Thursday it was closely monitoring President-elect Donald Trump’s continued pursuit of Greenland.

Earlier this week, Trump said he would not rule out using military force to seize the strategically important Arctic island, an autonomous Danish territory, saying it was in U.S. economic and national interests.

Trump’s comments received some support from pro-Kremlin figures in Russia, some of whom are close to President Vladimir Putin Any move to assert U.S. sovereignty over Greenland would legitimize Russia’s own expansionist goals and the ambition to restore former Soviet territories, such as the Baltics, to their sphere of influence and power.

European leaders have warn President-elect Trump opposes the occupation of Greenland, saying the move would violate international borders, while Denmark and Greenland say the island, where the United States has a military base, is “not for sale.”

The Kremlin made its first public comment on the matter on Thursday, with press secretary Dmitry Peskov saying Russia was closely monitoring developments.

According to comments, Peskov told reporters on Thursday: “Such statements may be more of a matter of bilateral relations between the United States and Denmark.” According to Russian state news agency TASS and translated by Google.

“We are closely following the dramatic developments of the situation, but thank God so far (the situation remains) at the level of declarations,” Peskov said.
