U.S. President Donald Trump has announced a 10 percent tariff on imports from eight European countries, citing their opposition to his position on Greenland. The affected nations are the United Kingdom, Germany, France, Denmark, Norway, Sweden, the Netherlands, and Finland. The tariffs will take effect on February 1, with plans to raise the rate to 25 percent on June 1. Trump made the announcement on his social media platform Truth Social on Saturday.

In his post, Trump claimed that it is time for Denmark to “return” Greenland and argued that the current situation poses a threat to world peace. He alleged that China seeks to take over Greenland and that Denmark is incapable of responding effectively. Trump also accused the European countries of playing a “very dangerous game” in Greenland and said strong measures are needed to end the situation quickly.

During a White House meeting on Friday, Trump reiterated that any country disagreeing with his stance on Greenland could face tariffs, emphasizing the island’s strategic importance to U.S. national security.
