 Ladies and gentlemen, good morning. I'm Shou Pinyi, the General Director of Space Law Center of China National Space Administration. First, I would like to thank the CERCUE World Foundation for inviting me participating in the second summit for space television. And also congratulate the opening of the summit. Space television is the goal and guarantee of human space activities. Here today, I would like to share some understandings about the topic with all of you. First, I think the core issue of space television is the safety and security of all space. Secondly, the main fact affecting and threatening the space satellite unit include space debris, the military use of all space activities, and natural factors such as space weather. Moreover, it also includes the current construction of mega-consolation of small satellite without restriction. Thirdly, the realization of space satellite is a comprehensive system project which requires not only legal measures to improve the legal mechanism for space satellite but also scientific and technological cooperation. Both China and the US should be the leading force in achieving space satellite unit. However, currently, they are not a joint force to achieve the satellite of all space. I think without the cooperation between China and the US, it will be more difficult for the international community to build a scientific and sound mechanism for achieving space satellite unit. So, I believe that through the China-US space dialogue, deepening understanding and including trust are the foundation for the international community to build a scientific and sound mechanism for space satellite unit. On the one hand, China and the US should jointly promote the formation and development of relevant laws and regulations on space satellite unit through dialogue. On the other hand, through dialogue, China and the US may understand and include in trust with each other and thus jointly promote the international community to strengthen international cooperation in space science and technology for all space satellite unit. Ladies and gentlemen, space satellite unit is a common aspiration of international community. As major space power in the world, China and the US have the ability and the obligation to guide the international community for the improvement and development of the satellite unit mechanism in outer space. The premise of the above is that China and the US can increase mutual trust and reach consensus through space dialogue. Thank you.
