Venezuela’s government on Thursday approved opening the country’s oil sector to private investors. As lawmakers finalized the overhaul, the U.S. Treasury Department began rolling back restrictions that had strangled Venezuela’s oil output and widened the scope for American firms to operate there. Earlier this month, President Donald Trump said Venezuela will direct revenue from a new oil arrangement exclusively toward buying American-made goods. “Venezuela is committing to doing business with the United States of America as their principal partner — A wise choice, and a very good thing for the people of Venezuela, and the United States,” Trump said. Analysts said American companies originally built and led Venezuela’s oil industry before Hugo Chávez brought it under state control.
