NICOSIA, May 25 (AFP) - Cyprus turned away a Serbian government minister who arrived at the island's main airport Friday in the first reported enforcement here of an EU travel ban, Foreign Minister Yiannakis Cassoulides said Tuesday. Minister without portfolio Bogoljub Karic arrived at Larnaca airport with his sister on a Malev flight from Budapest, Cassoulides said. Although a frequent visitor to the island, Karic was turned away in the spirit of the European Union's travel ban on 300 or so alleged associates of Yugoslav President Slobadan Milosevic, he said. The minister heads the Karic Banka offshore bank based in the island's second city of Limassol. Cassoulides's announcement that Cyprus had denied Karic entry came amid mounting EU concern about the island's policy on the Kosovo crisis which is threatening to hamper its accession negotiations. The government announced late last month that it would back tightened EU sanctions against Yugoslavia despite strong support among Greek Cypriots for their follow Orthodox Serbs. "The government has decided to align itself as far as possible with the new measures which the EU has decided to take," government spokesman Costas Serezis said after a cabinet meeting two weeks ago. But it now appears the government may have to introduce new legislation to implement some of the EU sanctions, in particular a freeze on Yugoslav assets abroad. ""In my opinion it's doubtful whether the Central Bank has the legal right to freeze assets," bank governor Afxentios Afxentiou told reporters Tuesday. New legislation is unlikely to be approved by a hostile parliament which has already passed a symbolic resolution opposing Cyprus's enforcement of the sanctions. Cassoulides said the government was waiting for the attorney-general's advice this week on whether fresh legislation was necessary. But he confirmed that the government's potential failure to fulfil the requirements of the EU's common foreign policy on Kosovo had already prompted current EU president Germany to express concern about its impact on the progress of Cyprus's membership negotiations. "If Cyprus wants to join a club such as the EU and the EU has studied and is following a policy, then you can't put yourself against this and expect the club to say you're most welcome," a German embassy spokesman said. The eastern Mediterranean island is one of six candidates for accelerated accession to the European Union. Newspapers here have reported that Milosevic has millions of dollars of his own personal wealth stashed away in offshore banks on the island. At least four of the islands's 30 offshore banking units are Yugoslav, including Nicosia's Beogradska Banka. There are also a number of Yugoslav shipping and other firms among the 36,500 offshore companies licensed on the island, although the authorities here do not divulge the names or number.
