Guaidó has declared himself interim president and has been recognised as such by dozens of countries, including Argentina, but Maduro, buoyed by support from the armed forces, has declined to step aside.
In an interview with AFP, Guaidó discusses the entry of foreign aid, contact with the military and whether he would be willing to allow the highly-controversial step of foreign military intervention.
Would you use your prerogatives as speaker of the National Assembly and acting president to authorise the intervention of foreign military forces?
We will do everything possible, once again, this is obviously a very, very controversial subject, but making use of our sovereignty and, within our jurisdictions, we will do what is necessary.
I am sure that Moscow and Beijing know the situation in Venezuela really well: Maduro doesn't have the popular support and he can't stabilise the economy, which produced the world's largest inflation of two million percent.
Would you receive emissaries of the International Contact Group seeking a negotiated solution?
"We are ready to talk with everyone, with a very specific agenda."
