Singapore, June 11 (Reuters) - Saudi crude oil sales to China are expected to remain at record lows in July, sources familiar with the matter said, as high prices resulting from Iran's war continue to weigh on demand in the world's largest oil importer.

The quotas, which are closely watched by market participants as a gauge of Chinese demand, indicate that refiners remain reluctant to import high-priced crude following the reduction in refinery runs and the drawdown of domestic stockpiles.

Sources said Saudi Aramco will ship around 12 million barrels of oil to its customers in China for loading in July, equivalent to about 387,096 barrels per day . The sources requested anonymity because they were not authorized to speak to the media.

Sources said that Sinopec, the world’s largest refiner by processing capacity, did not buy any Saudi crude oil for the second month in a row.

Purchases by another major refiner, Rongsheng Petrochemical, were far below pre-war levels.

The purchase decisions came after Aramco cut its official selling prices for July to Asia by six dollars a barrel compared to the previous month, although they remained well above pre-war levels.

Chinese refiners cut operating rates after rising crude oil costs and weak fuel demand led to refining losses, resulting in oil imports in May falling to their lowest level in a decade.

Aramco, Sinopec and Rongsheng have not yet responded to requests for comment.
