French President Emmanuel Macron, who last week called Venezuela a dictatorship, will on Monday meet with opposition representatives, including the president and vice-president of the opposition-governed congress, Macron's office said.
The situation in Venezuela has a particular resonance in France, where the far-left France Unbowed party, currently Macron's most vocal opponent, backs Maduro.
Human rights activist Lilian Tintori, the wife of Venezuela's best-known detained political leader, Leopoldo Lopez, said on Saturday she had been barred from flying out of the country to go to France and other EU capitals.
"The dictatorship does not want my voice to be head abroad. But the tour is going ahead. @FreddyGuevaraC will represent @leopoldolopez and me," she wrote on her Twitter page on Sunday, referring to Congress Vice President Freddy Guevara.
Congress President Julio Borges will also be there, Macron's office said.
Venezuela's opposition says President Nicolas Maduro's socialist government has stepped up repression of opponents this year, while officials say they are acting to stop violent coup plots fomented by the United States and other foreign powers.
Macron last week said that Maduro's administration "a dictatorship trying to survive at the cost of unprecedented humanitarian distress."
