CHONGQING, China/SINGAPORE, Dec 29 (Reuters) - China plans to launch a natural gas exchange in Chongqing in early 2018, aiming to create an Asian price benchmark as the nation's use of the fuel surges amid its shift away from coal.

China is the world's third-biggest consumer of natural gas behind the United States and Russia. An exchange in its fast-growing market would be a strong contender for an Asian gas marker off which other supplies in the region could be priced.

The Chongqing Oil and Gas Exchange - supported by state energy majors, and private and local government-backed gas distributors - would provide a trading platform for domestic output, pipeline imports from Central Asia and Myanmar, and imports of liquefied natural gas (LNG).

Chongqing is China's second attempt to develop a traded gas market, having set up a similar exchange in 2015 in Shanghai.

An Asian gas price benchmark to stand next to those of the United States and Europe is seen as a key missing piece in establishing a truly global market for natural gas.

"The exchange is a product of the government's reform push - to hand the pricing power to the market," Exchange Chairman Zhang Bowen told Reuters.

"The long-term goal is to build the exchange into a benchmark for Asia and to win China its deserved pricing power," said Zhang, who was previously president of PetroChina Kunlun Energy.

The exchange, led by a board of nine directors including a former PetroChina executive and an ex-senior state planning official, expects to launch electronically-based spot trading of pipeline gas and LNG imports in the first half of next year.

Registered in Chongqing municipality in July with 1 billion yuan ($150 million) in capital, the exchange has a team of 30, including former market developers at state-owned energy giants CNOOC and Sinopec.

"A China gas hub certainly looks attractive from a supply/demand and infrastructure perspective," said Jeff Brown, president of consultancy Facts Global Energy (FGE).

Chongqing exchange is appraising around 200 potential members, mostly from the consuming hub of eastern China, and will be open to foreign participation in the longer run, said exchange executives.

PRICING CONTROLS A BARRIER

Still, there are several challenges to overcome, for Chongqing or any other exchanges hoping to establish an active gas trading platform.
