The European Union will gain its 28th member on 1 July, once all members ratify the agreement.
19 members have already agreed to Croatia’s membership to the union and the European Commission said that Croatia is ready to join.
"We are confident that Croatia will be ready to join the EU on 1 July 2013," EU Enlargement Commissioner Stefan Fuele said after talks in Zagreb on Tuesday.
"This report is a clean bill of health."
"EU membership is an additional incentive to carry on with reforms. Croatia is expected to continue developing its track record in the field of the rule of law, notably in the fight against corruption," he said.
