Overseas investment increased to 18.7 billion U.S. dollars last year.
The report said energy output had grown by an annual average of 4.7 percent to hit 2.35 billion tonnes of standard coal equivalent, second only to the United States.
The country's energy supply was adequate for 90 percent of its domestic demand, said the report.
