Saudi Arabia’s crude oil exports to China are set to fall in September, slipping from a more than two-year high in August after the world’s largest exporter raised prices, several trade sources said on Monday.

State oil firm Saudi Aramco 2222 will ship about 43 million barrels to China in September, or 1.43 million barrels per day (bpd), a tally of allocations to Chinese refiners showed.

That is down from 1.65 million bpd allocated in August.

Companies which planned to reduce Saudi crude liftings in September include Asia’s top refiner Sinopec 600028 and its Fujian Refinery joint venture with Saudi Aramco, the sources said.

PetroChina 601857 and Shenghong Petrochemical will also slightly reduce volumes in September from August, they added.

Last week, Saudi Aramco hiked its September crude prices for Asian buyers for the second month in a row on robust demand.

The price of flagship Arab Light crude rose to $3.20 a barrel above the average Oman/Dubai quotes, the highest premium since April, Reuters data showed.
