EU must show unity on Greenland, Ukraine, Board of Peace, preserve U.S. ties

The European Union must show unity in dealing with Greenland, the Board of Peace and return to discussions on helping Ukraine, which is the main security problem for Europe, Polish Prime Minister Donald Tusk said on Thursday.

Speaking to reporters before an emergency summit on EU relations with the United States, Tusk said Europe should be careful to preserve its ties with the U.S. but that Washington should also understand it should not try to dominate Europe.

"It is important for ...our partners in Washington to understand the difference between domination and leadership. Leadership is OK," Tusk said. "Coercion is not a good method in relation with our transatlantic partners," he said.

"I would like us to clearly confirm today that we can act as a political community on various issues, be it Greenland or the Board of Peace and primarily Ukraine, because ...it cannot be that ...the topic of Ukraine has been sidelined -- it is a key issue for the security of Europe," Tusk said

He added that Poland had expected progress on Ukraine peace talks this week at the World Economic Forum in Davos and the fact that Greenland became the key issue was bad news.
