In February, Sinopec will continue to accelerate its crude oil processing and plans to increase its capacity by 2.4 percent from last month.

One Sinopec official said the company processed crude oil at maximum capacity to ensure the oil supply could combat the agricultural drought. In January, the company increased crude oil processing by 7.2 percent year-on-year and 3.7 percent since December.

Currently, Sinopec's diesel stock in provinces like Henan, Anhui and Jiangsu increased significantly year-on-year. A stronger supply will be necessary when facing a drought.

In the second half of last year, China faced a tight supply of diesel because both Sinopec and CNPC (China National Petroleum Corp), the two energy giants in China, had low stocks.
