President: EU treaties shouldn't be revised in debates on multiple-speed Europe

"Lithuania strictly opposes any amendments to the EU treaties as they contain all the instruments for close and efficient cooperation – we only need to use them effectively," Grybauskaitė said in a press release issued during the EU summit in Brussels.

In the course of the meeting, leaders of EU states and governments are discussing the post-Brexit future of the organization. Guidelines of the EU's development for the next decade should be approved during a celebration of EU's 60-year anniversary in Rome on March 25.

Germany and France support the idea of groups of countries deciding to deepen integration in certain areas in the future, even without a general EU agreement. Lithuanian diplomats do not rule out the idea, however, are cautious about the possibility of unifying taxes or advanced defense integration in fears of reducing the role of NATO and US in Europe.
