Eight European nations released a joint statement on Sunday, saying they stood in solidarity with the Kingdom of Denmark and the people of Greenland, following US President Donald Trump's threat to annex the Arctic island.
"As members of NATO, we are committed to strengthening Arctic security as a shared transatlantic interest," Denmark, Finland, France, Germany, the Netherlands, Norway, Sweden, and Britain said in the statement.
The nations wrote that while they were ready to begin dialogues surrounding sovereignty and territory, "Tariff threats undermine transatlantic relations and risk a dangerous downward spiral."
"We will continue to stand united and coordinated in our response. We are committed to upholding our sovereignty."
The UK's Culture, Media and Sport Minister, Lisa Nandy, said in a statement to the BBC that "the future of Greenland is a matter for the people of Greenland and the people of the Kingdom of Denmark."
"I think this is actually a really serious issue," she said, "and I think it deserves a far more adult debate than us threatening the United States, and the United States threatening us."
Trump pushes add'l tariffs for countries opposing US ownership of Greenland
On Saturday, Trump stated he would implement a wave of increasing tariffs on the countries opposing the US's purchase of Greenland.
In a post on Truth Social, Trump said additional 10% import tariffs would take effect on February 1 on goods from these countries, all already subject to tariffs imposed by Trump.
Those tariffs would increase to 25% on June 1 and would continue until a deal was reached for the US to purchase Greenland, Trump wrote.
Trump has repeatedly insisted he will settle for nothing less than ownership of Greenland, an autonomous territory of Denmark. Leaders of both Denmark and Greenland have insisted the island is not for sale and does not want to be part of the United States.
