Liu said that the follow-up lunar exploration will focus on the south pole of the Moon.
"The hot spot of lunar exploration is the south pole of the Moon based on international consensus. More significant scientific discoveries lie in the permanently shadowed region of the Moon and the water in that region," said Liu.
Liu called on other countries to join hands in the lunar exploration. "The lunar exploration concerns all people's life and happiness. All countries should participate in the course and utilize the lunar space in a peaceful and lawful way," said Liu.
