WASHINGTON (Reuters) - The Trump administration ratcheted up pressure on Venezuela's President Nicolas Maduro on Wednesday, announcing U.S. recognition of the country's opposition leader as interim president and signalling potential new sanctions against its vital oil sector.
With street protests against Maduro underway across Venezuela, Trump said the United States recognised Juan Guaido, head of the opposition-controlled Congress, as the country's leader and called socialist President Nicolas Maduro's government "illegitimate."
"I will continue to use the full weight of United States economic and diplomatic power to press for the restoration of Venezuelan democracy," Trump said in a statement, encouraging other governments in the Western Hemisphere to also recognise Guaido.
The administration had been waiting to issue its announcement after Guaido had been sworn in as the country's temporary president on Wednesday, people familiar with the matter told Reuters.
U.S. Secretary of State Mike Pompeo, in a statement, called on Maduro to step aside and urged the country's military to support efforts to restore democracy.
Venezuelan opposition sympathizers had been urging Guaido to assume the presidency since Maduro was inaugurated to a second term on Jan. 10 following a widely boycotted election last year that the United States and many other foreign governments described as fraudulent.
The 35-year-old Guaido has energized the opposition with a campaign to declare Maduro a usurper and has promised a transition to a new government in a nation suffering a hyperinflationary economic collapse.
Guaido, a newcomer on the national scene who was elected to head Congress on Jan. 5, had said earlier he was willing to replace Maduro if he had the support of the military, with the aim of then calling for free elections.
U.S. officials in recent days had stated openly that Maduro no longer had a legitimate claim on power.
The sources acknowledged that formal recognition of Guaido would be complicated by questions of how to deal with Venezuela's U.S.-based diplomats and who would now control its bank accounts and other U.S. assets.
It was also unknown whether Guaido and the opposition-controlled Congress would now try to exert control over Citgo, the U.S. refining arm of Venezuela's state-run oil company PDVSA.
Such a move could also backfire if Maduro used Guaido's swearing-in and U.S. recognition of him as a pretext to take action such as detaining him.
Canada also plans to recognise Guaido, a Canadian government official said on Wednesday.
OIL SANCTIONS UNDER REVIEW
Adding to pressure on Maduro, multiple sources said the Trump administration could impose new U.S. sanctions on Venezuela's vital oil sector as soon as this week if the political situation there deteriorates further.
U.S. officials are considering a range of potential measures, including restricting U.S. imports of Venezuelan oil or even a full ban, to punish Maduro's government, but no final decisions have been made as Washington closely watches the street protests unfolding in the country, two people familiar with the matter told Reuters.
Two other sources briefed on the matter said the U.S. administration had privately informed U.S. energy companies of its deliberations.
The administration's decision on whether to go ahead could depend on how harshly Maduro cracks down on protesters and how he responds to Guaido's swearing-in, several of the sources said.
Since late last year, the White House has also been considering whether to put Venezuela's on the U.S. list of state sponsors of terrorism, U.S. officials have said.
The White House has been growing frustrated with existing sanctions on Venezuela which have so far spared oil exports, feeling they have not had the desired effect.
Cutting off Venezuela’s exports would choke off revenue to the Western Hemisphere’s only OPEC member-nation.
The United States has held off on broad, oil-related measures for now, mindful of the potential not only for deepening the suffering of the Venezuelan people but also the risk of causing problems for U.S. companies and consumers.
U.S. refiners such as Valero, Chevron and PBF Energy have had discussions about the possibility of such sanctions with the Trump administration in recent weeks, and companies have already started bidding up prices for alternative types of crude to replace the Venezuelan grades.
The sources said it was unclear whether a crude ban, if initiated, would be phased in or immediate, or whether it would also seek to cut off Venezuela’s ability to sell oil to other international buyers.
Venezuelan crude exports to the United States last year fell 15 percent to the lowest annual average in nearly three decades, according to Refinitiv Eikon data, as fast-declining oil output and financial sanctions continued to hit sales.
Still, some U.S. refineries have equipment specifically designed for heavy grades of crude like those from Venezuela. They imported about 500,000 barrels per day (bpd) last year, according to the U.S. Energy Information Administration.
