The liquefied natural gas refuelling market in China is still at an emerging stage due to its relatively high cost to process, liquefy and store compared with compressed natural gas. For our liquefied natural gas business model, the Group possesses strong upstream procurement suppliers formed by large-scale liquefied natural gas terminal companies. As vehicles containing special cryogenic storage facilities and tanks for liquefied natural gas use are required for transportation of liquefied natural gas, the Group uses the third party logistics service providers to transport our liquefied natural gas to our liquefied natural gas vehicular refuelling stations and to our wholesale customers. Our customers consist of retail and wholesale customers. Retail customers include end users who we provide gas refuelling service in vehicular refuelling stations, i.e. public bus operators, taxi drivers and private car drivers while wholesale customers are mainly other liquefied natural gas operators.
