WEST PALM BEACH, Fla. (AP) — President Donald Trump’s new executive order on Venezuelan oil revenue is meant to ensure that the money remains protected from being used in judicial proceedings.

The executive order, made public on Saturday, says that if the funds were to be seized for such use, it could “undermine critical U.S. efforts to ensure economic and political stability in Venezuela.”

The order comes amid caution from top oil company executives that the tumult and instability in Venezuela could make the country less attractive for private investment and rebuilding.

“If we look at the commercial constructs and frameworks in place today in Venezuela, today it’s uninvestable,” said Darren Woods, CEO of ExxonMobil, the largest U.S. oil company, during a meeting convened by Trump with oil executives on Friday.

During the session, Trump tried to assuage the concerns of the oil companies and said the executives would be dealing directly with the U.S., rather than the Venezuelan government.

Venezuela has a history of state asset seizures, ongoing U.S. sanctions and decades of political uncertainty.

Getting U.S. oil companies to invest in Venezuela and help rebuild the country’s infrastructure is a top priority of the Trump administration after the dramatic capture of now-deposed leader Nicolás Maduro.

The White House is framing the effort to “run” Venezuela in economic terms, and Trump has seized tankers carrying Venezuelan oil, has said the U.S. is taking over the sales of 30 million to 50 million barrels of previously sanctioned Venezuelan crude, and plans to control sales worldwide indefinitely.

“I love the Venezuelan people, and am already making Venezuela rich and safe again,” Trump, who is currently in southern Florida, wrote on his social media site on Saturday. “Congratulations and thank you to all of those people who are making this possible!!!”

The order says the oil revenue is property of Venezuela that is being held by the United States for “governmental and diplomatic purposes” and not subject to private claims.

Its legal underpinnings are the National Emergencies Act and the International Emergency Economic Powers Act. Trump, in the order, says the possibility that the oil revenues could be caught up in judicial proceedings constitutes an “unusual and extraordinary threat” to the U.S.
