As the outbound supporting pipeline project for the Tangshan LNG Project and the key project for the construction of natural gas infrastructure in the Bohai Rim region, the Caobao Section Outbound Pipelines Project is the key project for the national natural gas infrastructure interconnection in 2019. After the completion of the Caobao Section Outbound Pipelines Project, it will connect to the LNG terminal project in Tangshan, which can transport the overseas high-quality LNG gas introduced by the Tangshan LNG Project to the hinterland of Hebei Province, and realize interconnection through the gas pipelines, such as China-Russia East Line ( 中俄東線), Shaanxi-Beijing System ( 陝京系統) and Yongtangqin ( 永唐秦). It will optimise the increase in the supply and reserves of natural gas in Hebei Province and surrounding areas and the emergency peaking capability, secure regional gas supply safety and optimise the structure of energy consumption in order to improve the quality of the atmospheric environment as well as promote economic and social development. The completion of construction of the Tangshan LNG Project and the Caobao Section Outbound Pipelines Project would enrich the business types of sources of gas of the Company and further diversify the sources of gas of the Company. With such benefits, the Company can therefore accelerate its expansion in gas business market, optimize the business structure of the Company and increase the proportion of the Company's gas business.

Shareholders of the Company and potential investors are advised to exercise caution when dealing in the shares of the Company.
