CNOOC is a major gas importer

With the delivery of 67,000 metric tons of liquefied natural gas to Guangdong province on Sunday, China National Offshore Oil Corp has imported more than 100 million tons of LNG in the past 10 years, accounting for 80 percent of the country's total imports.

As China, the world's biggest energy consumer, is raising the percentage of clean energy being used in order to reduce emissions, CNOOC is eyeing LNG as another pillar industry after oil.

The company's gas production accounts for 18 percent of the company's total, and gradually rise to around 20 percent in the near future.
