CARACAS, Venezuela – Representatives of the Venezuelan government and opposition have returned to Norway for talks aimed at resolving the political crisis in the South American country, the Norwegian government said Saturday. Norway said it will mediate discussions next week in Oslo, in an indication that the negotiation track is gaining momentum after months of escalating tension between Venezuelan President Nicolás Maduro and Juan Guaidó, the U.S.-backed opposition leader. Top Maduro aide Jorge Rodríguez and Héctor Rodríguez, the governor of Miranda state, both of whom were in Oslo earlier this month for an earlier round of exploratory talks, will once again lead the government delegation.
