China: Saudi Arabia emerges the biggest oil supplier

Chinese crude oil imports from Russia in August surged 28% from a year earlier, but handed back its top supplier ranking to Saudi Arabia for the first time in four months.

Imports of Russian oil, including supplies pumped via the East Siberia Pacific Ocean pipeline and seaborne shipments from Russia's European and Far Eastern ports, totaled 8.342 million tons, data from the Chinese General Administration of Customs showed.

The August amount, equivalent to 1.96 million barrels per day (bpd), was slightly off May's record of nearly 2 million bpd.

China is Russia's largest oil buyer.

Russian imports rose as Chinese independent refiners extended purchases of discounted Russian supplies that elbowed out rival cargoes from West Africa and Brazil.

Emma Li, China analyst with Vortexa Analytics, said actual Russian supplies are likely at par with Saudi shipments at close to 8.5 million tons. Several cargoes of Russian Urals crude were reported as originating in Malaysia, according to ship-tracking data she has compiled.

Tuesday's customs data showed imports from Malaysia, often used as a transfer point in the past two years for oil originating from Iran, Venezuela and more recently Russia, nearly doubled from a year earlier, to 3.37 million tons, or 794,000 bpd, at record high.

China's purchases from Russia have climbed to reap the benefits of a plunge in European buying as the Ukraine crisis pushes Moscow in search of alternative markets. 

Still, imports from Saudi Arabia rebounded last month to 8.475 million tons, or 1.99 million bpd, 5% above a year ago levels.

Saudi Arabia also remains the biggest supplier on a year-to-date basis, shipping 58.31 million tons of oil from January to August, down 0.3%YoY, as compared to 55.79 million tons from Russia, which was up 7.3% from a year ago.

China's crude oil imports in August fell 9.4% from a year earlier, as outages at state-run refineries and lower operations at independent plants caused by weak margins capped buying.

The strong Russian purchases continued to weigh on competing supplies from Angola and Brazil, which fell in August by 34% and 47%YoY, respectively.

Customs reported no imports from Venezuela or Iran last month. State oil firms have shunned purchases since late 2019 avoiding likely secondary US sanctions.

However, Reuters reported that defense-focused China Aerospace Science and Industry Corp (CASIC) has moved 25 million barrels of Venezuelan crude into China since late 2020, which Chinese customs does not report.

China also did not import any crude from the United States.
