China's crude oil processing volume grew 29 percent year-on-year in January, as economic recovery pushed up demand for oil products.

The country processed 30.14 million tons of crude last month. Output of refined oil increased 24 percent to 18.59 million tons, according to the China Petroleum & Chemical Industry Association (CPCIA).

Economic recovery is the main reason for the rapid growth, said Lin Boqiang, a professor at Xiamen University. "The solid economic rebound has spurred demand for oil products, and the growth will continue in the next few years."
