Croatia and Slovenia concluded an agreement on March 7 to settle a banking dispute that has divided the two countries for 20 years, clearing the way for Croatia’s accession to the EU on July 1, 2013.

According to the memorandum, which will now be signed by the heads of government from both countries on March 11 in Ljubljana, negotiations on the long standing financial wrangle will continue under the auspices of the Bank for International Settlements in Basel, Switzerland. For its part, Croatia has pledged to abandon on-running legal action against the Slovenian bank, Ljubljanska Banka.

Between now and the end of March, the Slovenian parliament is set to ratify the treaty on Croatian accession to the EU, which has already been approved by 21 of the EU’s 27 member states.
