Leaders of EU countries will hold an emergency summit on Thursday to discuss U.S. threats related to Greenland, European Commission spokesperson Olof Gill said on Monday.

The summit will consider possible retaliatory measures in response to threatened tariffs by U.S. President Donald Trump on countries opposing his plan to "acquire" Greenland.

Gill said the EU is engaging "at all levels" with Washington over the new tariff threats and taking "every possible step" to protect the bloc's economic interests. He added that the use of the anti-coercion instrument is not ruled out.

He emphasized that engagement, rather than escalation, remains the priority with the United States. "Should the threatened tariffs be imposed, the European Union has tools at its disposal and is prepared to respond," he said.
