BEIJING, Jan. 18 (Xinhua) -- China on Monday unveiled regulations on lunar sample management, encouraging international cooperation on studying the samples brought back by the Chang'e-5 probe.

Released by the China National Space Administration (CNSA), the regulations cover general principles for preserving, managing, using, borrowing and returning the lunar samples, as well as information release and research results management of the samples.

According to the regulations, the lunar samples will be generally used for four purposes, namely permanent storage, backup permanent storage, research and public welfare.

The Chang'e-5 probe, comprising an orbiter, a lander, an ascender, and a returner, was launched on Nov. 24, 2020. The return capsule landed in Inner Mongolia Autonomous Region on Dec. 17, retrieving about 1,731 grams of lunar samples.

China encourages international joint research in space science based on the lunar samples to support science results sharing, said Zhang Kejian, head of the CNSA, noting that the management and usage of the samples would comply with relevant international conventions.

Diplomats and representatives from France, Russia, the European Union, Asia Pacific Space Cooperation Organization and other countries and international organizations were invited to visit the lunar sample storage and processing facilities in the National Astronomical Observatories of China under the Chinese Academy of Sciences on Monday.

The CNSA also awarded commemorative plates to the international cooperators including the Argentine National Space Activities Commission, European Space Agency, Namibia Ministry of Higher Education, Training and Innovation, and Pakistan Space and Upper Atmosphere Research Commission, to thank them for their collaboration during the Chang'e-5 mission.

Based on the principle of equality and mutual benefit, peaceful utilization and win-win cooperation, the CNSA has actively carried out international cooperation in lunar exploration, Mars exploration, satellite projects, and launch services, to promote the common progress and long-term sustainable development of the space industry, Zhang said.

"We are still in the pre-processing stage of the lunar samples, including sample unsealing, preparation and the establishment of archives," said Pei Zhaoyu, deputy director of Lunar Exploration and Space Engineering Center of CNSA.

About 80 percent of the lunar samples will be used for scientific research, and 20 percent will be preserved for better and more advanced scientific research methods and conditions in the future. This also constitutes protection of heritage of human civilization, Pei added.

China's future lunar and interplanetary exploration missions will be more open, and cooperation among countries will be further encouraged, Pei said.
