Encouraged by lower prices, Chinese firms have ramped up purchases of Russian oil this year. Official figures show that imports of Russian oil rose by 55% from a year earlier to a record level in May. The imports, which include supplies pumped through the East Siberia Pacific Ocean pipeline and shipments by sea from Russia's European and Far Eastern ports, totalled nearly 8.42m tonnes last month, according to data from the Chinese General Administration of Customs. That pushed Saudi Arabia - formerly China's biggest source of crude oil - into second place with 7.82m tonnes.

由于油价下跌，中国企业今年增加了对俄罗斯石油的采购。 官方数据显示，5月份俄罗斯石油进口量同比增长55%，创历史新高。 中国海关总署的数据显示，包括通过东西伯利亚太平洋管道输送的供应，以及从俄罗斯在欧洲和远东港口通过海路输送的供应，上月进口总量达到近842万吨。 这将中国以前最大的原油进口地沙特阿拉伯推至第二位，其进口量为782万吨。
