Venezuela's state oil company PDVSA has canceled several authorizations it had granted U.S.-based producer Chevron to load and export Venezuelan crude in April, three sources with knowledge of the decision said on Thursday.

This development comes after Washington cancelled key licences last month for several PDVSA partners including Chevron.

Venezuelan state-owned PDVSA has revoked authorizations for U.S. supermajor Chevron to load and export crude oil, following the Trump Administration's increased sanctions and tariffs on Venezuelan oil exports and buyers.
