China's space officials have invited global scientists to study lunar rock samples from the Chang'e 6 mission, but highlighted restrictions on cooperation with the United States due to the Wolf Amendment. The Wolf Amendment, in place since 2011, prohibits direct U.S.-Chinese bilateral collaboration in space unless certain conditions are met. Despite this, China is open to working with scientists from other countries and has engaged in partnerships with various nations for the Chang'e 6 mission. The Chinese space agency emphasizes the need for the U.S. to address these obstacles to foster regular aerospace cooperation. International researchers are encouraged to apply to study the lunar samples and participate in scientific research on the moon's geological mysteries.
