The meeting of the Council of the Common Market Mercosur scheduled for next Saturday, which was to treat the transfer of the EU presidency to Venezuela, was canceled, Efe reported Wednesday Uruguayan government sources.The reason for cancellation is communication by Paraguay and Brazil that did not attend the meeting.Uruguay is intended to confirm that the July 30 block completes its mandate, although Brazil and Paraguay are reluctant to finalizing the transfer.Uruguay currently holds the pro tempore presidency of the South American group and the order of rotation thereof corresponds to Venezuela assume the mandate for the next six months, something that does not convince all Member States of the block (also composed of Argentina, Brazil and Paraguay) due to the political situation in the country.Nor is there unanimity as to the interpretation of the Treaty of Asuncion (founding group agreement signed in 1991) and the Protocol of Ouro Preto (1994) on how you have to make the transfer.Venezuela interprets the command transfer is automatic, while other group members understand that the decision should be taken by consensus.
