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

Venezuelan President Nicolas Maduro on Wednesday said his government would continue producing oil, a day after the United States gave energy giant Chevron a month to stop operations in the Caribbean country.

The Trump administration made a dramatic move Tuesday, ceasing an important operating license the American oil giant Chevron needed to operate in Venezuela. The decision follows Washington’s condemnation of President Nicolás Maduro’s government for not making concrete advances on key electoral reforms.
