Euro zone finance ministers will work on a financing for reforms deal with Greece on the basis of a proposal from the creditor institutions as negotiations with Athens have produced no agreement - euro zone officials said on Thursday. Euro zone finance ministers are to start talks in Brussels at 1330 CET (1130 GMT) on the basis of an offer agreed on in Berlin at the beginning of June between Germany, France, the European Central Bank, the International Monetary Find and the European Commission. In EU jargon it is called "aide memoire".
