Less popular among Latin leaders, the Venezuelan president is on an 11-day trip to visit allies including Libya's Qaddafi and Iran's Ahmadinejad.
Opponents are organizing a massive march for Saturday in Caracas, disregarding warnings by Venezuela's top federal prosecutor that protesters could face prison sentences of up to 24 years for disturbing the peace.
"We dare the government to put into prison not only the leaders of the 25 groups heading up the march but the hundreds and hundreds of people who will call for a democratic end to this government," Henry Ramos, head of the Accion Democratica political party told a crowd of supporters on Wednesday.
