GENEVA, Feb 1 (Reuters) - Australia, Brazil and Thailand called on Monday for the immediate withdrawal of an additional export of 500,000 tonnes of out-of-quota sugar by the EU in the 2009/2010 marketing year and said it was a prohibited subsidy under World Trade Organisation rules. The three states, who won a WTO dispute against the EU over sugar exports, said in a statement they were reviewing the EU measure and did not rule out further action.
