Presidents Evo Morales of Bolivia and Rafael Correa of Ecuador have been invited to a rally to be headed next Friday by Venezuelan President Hugo Chávez in a stadium of Buenos Aires, hosts told Efe Tuesday.

"It seems that Morales is coming and there are plans for Correa to come also," said sources of Madres de Plaza de Mayo, the organizers of the event along with other 40 social, political and human rights agencies based in Argentina.

In addition to express support to Chávez, the groups will conduct the rally in order to refuse the visit of US President George W. Bush. The ruler is to kick off ending this week a tour of five Latin American nations.

Morales arrived last Monday in Tokyo for an official, four-day visit and "if he manages to sort out some protocol issues, will come to the event," sources said.

For his part, Chávez will land in Buenos Aires next Thursday. He is expected to meet with his Argentinean counterpart Néstor Kirchner and visit Sancor, a dairy manufactory funded by the Venezuelan Government.
