China, the world's largest energy user, can maintain steady growth in annual oil and natural gas output beyond 2030, the Ministry of Land and Resources said on Wednesday.

Crude oil and natural gas production in 2030 will be more than double the figure for 2013, which was about 330 million metric tons of oil equivalent, the ministry said.

One TOE is equivalent to the approximate amount of energy that can be extracted per metric ton of crude oil.
