Following a meeting with eight South American foreign ministers, Nicolas Maduro said on Monday that he had agreed to talk with opposition members on Tuesday, AFP reported.
"We had quite a long conversation," Maduro said of the regional talks. "They proposed a meeting tomorrow with the opposition delegation, and I agreed."
However, only a small number of those opposing the government have agreed to participate in the talks.
The more moderate Democratic Unity Roundtable coalition, which seeks change without unseating Muduro, said it would join the president for Tuesday's discussions.
Maduro said he hoped the coalition would not backtrack on the talks.
Maduro, elected in 2013 after the death of Hugo Chavez, has lashed out at the demonstrations, calling them a "fascist", US-backed plot to overthrow his government.
