"President Dalia Grybauskaitė underlined that it was in the interest of Lithuania as well as of the entire EU to avoid an uncontrollable Brexit and ensure that it does not cause any negative consequences to Europe and the United Kingdom," the presidential press service said in a statement.
Meeting in the Austrian city of Salzburg, EU leaders discussed ways to put the final touches in the negotiations on Brexit conditions. Two more European Council summits in October and Novermber will be dedicated to the issue of Britain leaving the EU.
The issue of the Irish border remains one of the matters causing majors debate.
"Lithuania and the other EU member states hold a consistent position that the agreement between the EU and the United Kingdom should ensure that there will be no border between Ireland and the Northern Ireland," the statement said.
If this issue is not resolved, the UK might have to leave the EU without a deal, which, EU and British experts believe, would undermine economic and financial ties between London and Brussels.
Also in Salzburg, Grybauskaitė presented Lithuania’s proposal to introduce a single standard for the protection of EU external borders.
