And whether President Nicolas Maduro consolidates his power, or opposition leader Juan Guaido takes control of the government, one longterm question hangs over the country's fate: "Who gets Venezuela's oil?".
The representatives include Jorge Rodriguez, Mr Maduro's information minister, and Stalin Gonzalez, a leading member of the national assembly, according to the reports.
Venezuelan President Nicolas Maduro did not directly comment on the talks in televised remarks on Wednesday, but said Rodriguez was on a "very important" mission outside Venezuela.
Delegates from both sides of Venezuela's political crisis have traveled to Norway for talks aimed at resolving the country's worsening political crisis.
"There are some envoys in Norway", Guaido told a rally of his supporters in Caracas.
At 9:30 a.m., Washington city police officers illegally entered the Venezuelan Embassy in the Georgetown neighborhood and arrested four activists who have lived legally in the building since April 10 as guests of the legitimate Venezuelan government, the group said in a statement.
Norway's Foreign Ministry said in March that it was ready to act as a mediator or facilitator of talks between the Venezuelan government and opposition.
The measure reflected the increasingly sour relationship between the Venezuelan government and the US, which is leading a campaign to oust President Nicolas Maduro.
Calling Maduro a dictator, U.S. President Donald Trump has tightened sanctions against his government and spearheaded global recognition of opposition leader Juan Guaido, who in January invoked the constitution to assume the interim presidency. Maduro, in turn, alleges the opposition tried to seize power by force.
Norway has a tradition of conflict mediation, including assistance with Colombia's 2016 peace deal between the government and FARC rebels.
Copa Airlines, which operates flights between Caracas and its global hub in Panama City allowing passengers to continue on to the United States, said in an email that its operations would not be affected by the measure.
Guaido swore himself in as "interim president" on January 23, and was immediately backed by Washington and other allied countries. An economic downturn has driven more than 3 million Venezuelans to emigrate, fleeing hyperinflation and shortages of food and medicine.
