Noting the city should seize opportunities brought by the nation's development and integrate into the nation's overall development, Ip said Hong Kong should encourage more young people to engage in and devote themselves into scientific research work.

Hu Hao, chief designer of China's third-phase lunar exploration program, said Hong Kong has a solid technological foundation and a pool of quality talents to contribute to the nation and Hong Kong.

"I'm looking forward to Hong Kong's active participation in the research of lunar samples, as well as its wider and deeper engagement in following national space projects," Hu said.
