China calls on scientists of all nations to study lunar samples, but notes obstacle with the US

China's space officials announced that scientists worldwide could apply to study lunar rock samples from the Chang'e 6 mission. Cooperation, however, excludes the U.S. due to the Wolf Amendment, which restricts direct bilateral collaboration with NASA. China welcomes international scientists but refrains from revealing specific sample details pending further announcements. Future plans include lunar and planetary exploration missions.
