China brought in 7.42 million tonnes of coal from Russia last month, data from the General Administration of Customs showed on Saturday. That was the highest monthly figure since comparable statistics began in 2017, up from 6.12 million tonnes in June and 6.49 million tonnes in July 2021.
Western countries were avoiding cargoes from Russia ahead of a European Union ban on Russian coal that came into force on Aug. 11, aimed at reducing the Kremlin's energy revenue over its February invasion.
The ban has forced Russia to target buyers such as China and India and sell at a steep discount.
Russian thermal coal with a heating value of 5,500 kilocalories (kcal) traded around $150 a tonne on a cost-and-freight basis in late July, while coal of the same quality at Australia's Newcastle port was assessed at more than $210 a tonne on a free-on-board (FOB) basis.
Some Chinese traders expect more Russian coal to flow into China in the fourth quarter when utilities in northern China build stocks for the winter heating season.
July shipments of Indonesian coal, mostly cheap, low-quality thermal coal with a heating value below 3,800 kcal, were 11.7 million tonnes. That was up 22% from June but down 40% from a year earlier. China has reduced its overall coal imports in recent months amid surging domestic output.
Power plants in southern China have increased tenders to buy Indonesian coal in August as it is cheaper than domestic coal, while demand for coal-fired power generation has been boosted by a record heat wave.
Indonesian thermal coal with a heating value at 3,800 kcal changed hand at about $78 a tonne on a FOB basis last week, which would still below about 690 yuan ($101) for local coal when considering shipping costs.
China's customs data showed zero coal shipment from Australia in July.
