Abstract：The theme report for the 4^th Global Forum on Energy Security Conference is completed by the Task Force of The Institute of Quantitative & Technical Economics （IQTE） of Chinese Academy of Social Sciences （CASS）.

The energy security is recognized as a critical global issue of common concern. As the world's largest energy consuming country，China is facing an extremely serious energy security situation. After a rapid development for three decades since the reform and opening-up，China's economy has entered the New Normal，which not only provides us with opportunities for the structural adjustment，industry upgrading and social problems solving，but also brings new problems and challenges.

“One Belt，One Road” initiative is significant for the international energy cooperation. China puts forward the development concept of building “Silk Road Economic Belt” （SREB） and “21^st Century Maritime Silk Road” （MSR）. This strategic concept is accordance with China's inland and maritime energy import passage，which will help strengthen the energy ties between China and the countries along the passage. On the other hand，it will help to promote the regional integration and development，eliminate the development gap between different nations and eliminate the cradle for the extremism and terrorism through the cooperation in energy and traffic infrastructures，commercial，finance，and investment. If effectively implemented，it will bring our world more common interests beyond the anticipation.

For energy cooperation，it is necessary to highlight the infrastructure interconnection，as well as the currency，capital，trade，financial cooperation in order to promote the development of a common energy market in Asia. In reference to the successful experiences of common energy market in North America and the European Union，the common energy market in Asia can be developed by sharing the financial platforms. It is suggested in the report to promote the construction of three regional energy common markets in North-East Asia，Central Asia and Southeast Asia，and to construct natural gas trading centers for Eastern Asia and Southeast Asia by means of the “21^st Century Maritime Silk Road” Strategy. The following key projects are highly recommended.

A.The report puts forward to build the northern deep-water port，Caofeidian，as the natural gas market where the three major pipelines，namely eastern section of China-Russia natural gas pipeline，Central Asia and West-East Gas Pipeline and the offshore liquefied natural gas （LNG） import pipeline from the Western and Southeast Asia and Australia，are connected with the huge consumer market in circum-Bohai-Sea （CBS）region and Northeast Asia. To fulfill this target，it is necessary to connect the natural gas supply networks between China's northeast region and CBS region with that in Far East regions of Russia and part of the Republic of Mongolia. This natural gas market will integrate storage，delivery and billing into one system，and affect the area of Northeast and Southeast Asia. This will effectively adjust the China's energy structure，promote the cooperative development of Beijing，Tianjin and Hebei province （BTH），and reduce the air pollution. This strategy will enable the combination of the “21^st Century Maritime Silk Road” with Grassland Road and Silk Road，forming a new economic growth point in Asia.

B.To promote the interconnection between China-Central Asia energy pipelines with Pakistan-China economic corridor and the Western Asia energy networks for cooperative economic development of the western China，the five Central Asian countries，Pakistan as well as Western Asia and the Caspian coastal region. This area has a population of approximately 200 million，and has rich energy resources and market potential，therefore，making itself the key development area of the Silk Road Economic Belt. It will greatly promote the peace and development process in the Middle East and bring the world with significant security benefits if this development goal is fulfilled.

C.To push the energy cooperation between China and ASEAN，including enhancing the connectivity between China's Southern Power Grid and the electricity projects in Myanmar，Laos，Vietnam，Thailand，Cambodia to form a regional electricity networks，thus to improve the energy structure in southern China with clean hydropower. Also it is better to strengthen the cooperation between China and Singapore，Malaysia，Indonesia，Brunei and other countries in oil and gas and speed up the further integration of oil and gas markets in Eastern and Southeast Asia and the formation of pricing centre in Eastern Asia.
