The US administration of Donald Trump is giving Chevron Corp. one month to stop producing oil in Venezuela, delivering a heavy blow to President Nicolas Maduro’s autocratic regime.

The Trump administration said on Tuesday it was ending a license that the U.S. had granted to oil producer Chevron since 2022 to operate in Venezuela and export its oil, after Washington accused President Nicolas Maduro of not making progress on electoral reforms and migrant returns.

The Trump administration formally revoked on Tuesday the license that allows oil giant Chevron Corp. to sell Venezuelan oil in the United States, giving the U.S. company only 30 days to wind down its operations in the South American country.
