Croatia votes to join EU in 2013 ZAGREB (Reuters) - Croatia voted Sunday in favor of joining the European Union in 2013, shrugging off concerns over the economic turmoil in the bloc, according to preliminary official results of a referendum. With 38 percent of votes counted, 67 percent had ticked 'Yes' to becoming the bloc's 28th member, the state electoral commission said, more than two decades after ?Croatia broke away from socialist Yugoslavia. Turnout looked unlikely to breach 50 percent of eligible voters, but there is no binding minimum for the referendum to be deemed valid. Opponents said the timing is all wrong because the EU is not what it once was, given the debt crisis threatening the single currency. Others complained they were unsure what membership will mean for the country of 4.3 million people. Croatia broke away from Yugoslavia in a 1991-95 war and missed the bloc's eastward expansion in 2004 and 2007. It saw strong growth in the past decade on the back of foreign lending and waves of tourists to its Adriatic coast, but its economy has been hit hard by the global economic crisis. Analysts and government officials say a rejection of EU accession Sunday would bring down the country's credit rating, deter investors and further dampen any prospect of a quick economic recovery.
