Since swearing himself in as the rightful leader of Venezuela on January 23, Guaido has led a campaign to try to wrest control of government assets overseas, including bank accounts, gold holdings, properties and USA refining unit Citgo. Maas said free and fair elections needed to be held quickly. The government has also responded to his challenge by cracking down on rebellious neighbourhoods, trying to preserve an autocratic, socialist-style system increasingly imperilled by deep unpopularity and foreign pressure. He has previously accused the U.S. of trying to orchestrate a coup.
In the conflict, millions of Vietnamese and tens of thousands of United States soldiers were killed. However, this time it does not resemble the old times, when the United States was free to do anything; instead, Venezuela is not a lone state.
In an interview with Russia's RIA Novosti agency, Maduro said he was willing to negotiate with the opposition and even offered to bring forward legislative elections - though dismissed the idea of a new presidential poll.
Maduro, who survived what he called an assassination attempt in August previous year, said he was well protected, guaranteeing him a long life. He says Maduro fraudulently won elections a year ago and is offering an amnesty to military officials.
Maduro does not provide any evidence that the USA government has control of the oil industries in either of those countries. He said he was aware of Trump's "orders" for the Colombian government and the local mafia to kill him.

On Monday, the US hit Venezuela's state-owned oil company with sanctions aimed at increasing pressure on Maduro to leave office.
Despite their increasingly militant opposition to Maduro, whom they regard as a dictator, both Washington and Bogota have repeatedly denied accusations of plots to kill him. "We must take to the street".
Support for dueling presidents in Venezuela has broken along traditional lines.
Last week, a group of soldiers rose up against Maduro.
Maduro and his supporters have waved away the European Union's demand that Maduro accept presidential elections by this weekend or the EU will recognise Guaido as president. He says, "Americans should not travel to Venezuela until further notice".
Mr Maduro's inauguration sparked protests throughout Venezuela. Unlike many other news organizations, we have not put up a paywall. "More and more people are being murdered", he said according to the German-language article.
The military high command remains loyal to Maduro but Guaido has tried to convince the rank and file to switch sides.
