BUENOS AIRES (Reuters) - Venezuela's Foreign Minister Delcy Rodriguez failed to get into a meeting of the Mercosur trade bloc on Wednesday after threatening to enter through the window if necessary, despite her country being thrown out of the group this month.
The meeting, at Argentina's foreign ministry in Buenos Aires, also grouped fellow South American nations Brazil, Uruguay, Bolivia and Paraguay.
"If they close the door to us we will, as our president (Nicolas) Maduro has said, go through the window," Rodriguez told reporters outside the ministry.
"We will put on rubber-soled shoes and get in through the window ... Venezuela does not need an invitation because it is for the time being president of Mercosur."
Venezuela was expelled from Mercosur this month in part due to concerns about the government's human rights record.
Maduro's socialist government, which has lost allies in the region as various countries have moved to the right, says its suspension from the bloc is an unjustified and illegal "coup".
The pugnacious foreign minister was later allowed into the ministry building, through the door, to meet with Argentine Foreign Minister Susana Malcorra but stayed only briefly before exiting without gaining access to the session.
Venezuela joined Mercosur in 2012.
