PetroChina is this week unloading the first Chinese purchase of crude oil from U.S. strategic petroleum reserves at a port in eastern China, according to shipping data and two industry sources.
The move comes as China, the world's No.2 oil consumer, steps up imports from the Americas to diversify supply sources.
PetroChina unit, PetroChina International America Inc, bought the 550,000-barrel cargo of Bryan Mound sour crude in a sale from U.S. strategic petroleum reserves in March for $28.8 million.
