VATICAN CITY/CARACAS (Reuters) - Envoys for Venezuela's self-declared caretaker leader Juan Guaido met Vatican officials and lobbied the Italian government for support on Monday in their quest to keep international pressure on socialist President Nicolas Maduro.
The Vatican, which has offered to mediate, called for respect for rights and avoidance of bloodshed after Guaido's bid to end two decades of increasingly authoritarian leftist rule in the volatile OPEC member nation of 30 million people.
Members of the Vatican Secretariat of State met a delegation including Francisco Sucre, president of the foreign affairs commission of Venezuela's National Assembly, and Antonio Ledezma, former mayor of Caracas.
They also met Italy's deputy prime minister Matteo Salvini.
"We're in Italy to seek more support for our President @jguaido," tweeted Ledezma. "We're doing well, but we need to finish this with victory."
The Vatican "underscored the deep concern that a just and peaceful solution could be found urgently to overcome the crisis while respecting human rights, seeking the good of all the country's people and avoiding bloodshed," it said in a statement.
Pope Francis has said the Vatican could mediate if both sides asked. Maduro wants that, but Venezuela's opposition is skeptical given past dialogue failures and Guaido says the starting point for any talks must be Maduro's exit.
Venezuela's opposition regards Maduro as an incompetent dictator who has wrecked their economy and crushed dissent, while he calls them puppets of Washington seeking a coup in order to control the nation's vast oil reserves.
Rank-and-file opposition supporters, though often Roman Catholics, are suspicious of the Vatican given its support of past talks that have enabled Maduro to win time and survive various waves of protests.
Vatican Secretary of State Cardinal Pietro Parolin calls the Holy See's stance "positive neutrality", saying it has to stay above both sides if it is to help.
The Venezuela conflict has fed into a wider geopolitical struggle. Along with U.S. President Donald Trump, numerous Latin American and European nations have recognized Guaido as interim president and backed his calls for a new, free election.
But other powers, including Russia and China who have billions of dollars invested and loaned to Caracas, have denounced outside interference and backed Maduro.
Breaking the unity of other major European countries, Italy's coalition government is divided over Venezuela.
Salvini, far-right leader of the Northern League party and also interior minister, favors recognizing Guaido, but its coalition partner the 5-Star Movement believes that is a bad precedent.
Salvini telephoned Guaido while the Venezuelan delegation was visiting him, stressing his opposition to Maduro and support for a new vote, his office said.
Guaido, who heads Venezuela's opposition-led National Assembly, invoked a constitutional provision last month to declare himself president.
As well as the Vatican, Norway, another traditional international mediator, has also offered to help with dialogue.
