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

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.

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.
