Abstract: At present, the moon and Mars are the main focus of deep space exploration, scientific pursuits are the initial goal, and extensive cooperation leads to a greater prospect. China has made many scientific achievements and built considerable infrastructure through its lunar and Mars exploration activities. In the future, China will continue to carry out deep space exploration activities with scientific goals as the driving force, develop the International Lunar Research Station, explore the sun, inner planets and asteroids, discover exoplanets and build an asteroid defence system. 
In order to support future deep space exploration missions, China will construct an integrated communication, navigation and remote sensing constellation and develop heavy-lift launch vehicles. China offers a wide range of opportunities for cooperation, upholds the central role of Committee on the Peaceful Uses of Outer Space (UNCOPUOS), and welcomes all countries in the world to participate in deep space exploration activities.
