The licence reversal was attributed to President Nicolas Maduro's lack of progress on electoral reforms and migrant returns.

The United States is rescinding a Treasury license allowing Chevron to produce and export oil from Venezuela, despite U.S. sanctions, President Donald Trump said Wednesday, because President Nicolás Maduro was not legitimately elected and has not accepted Venezuelans deported from this country fast enough.

The move appeared to end Chevron’s work in the oil-rich country and was prompted by what the president said was a failure to accepted deportees.
