Exxon Mobil is negotiating a deal to produce oil in Venezuela nearly two decades after the company was forced to leave the South American country due to its socialist leadership.

In 2007, Exxon exited the nation after former Venezuelan President Hugo Chavez nationalized foreign-owned oil projects. The country has one of the world’s largest oil reserves, a key reason why President Donald Trump has prioritized its economic reopening since ousting former Venezuelan dictator Nicolas Maduro in January.
