Note the phrase "coal equivalent".
At the moment China burns about 3 billion tonnes of coal a year, mostly to generate electricity. They don't burn a lot of gas right now compared to other nations. They're planning a big increase in their total generating capacity up to about 2TW and a lot of that increase is going to be fuelled by gas as they cut back on coal but they're going to emit more CO2 in total in the process because of the increase.
Right now China burns about 2 tonnes of coal per capita each year. America burns about 3 tonnes of coal per capita annually but it also burns a lot more gas and oil per capita to power their first-world economy and infrastructure, military, road and air travel etc. China wants that sort of economy and infrastructure too.
