China on Tuesday announced the first astronaut candidates from its special administrative regions of Macau and Hong Kong, with the latter calling it a "glorious page" in the city's history.

Beijing has invested billions of dollars in its military-run space programme as it pursues ambitious plans for a manned lunar landing by 2030.

The China Manned Space Agency said Tuesday that a payload specialist from Hong Kong and another from Macau were among 10 candidates for the country's fourth batch of astronauts.

Hong Kong leader John Lee called it "a glorious page in Hong Kong's history".

"This is... the first time that a Hong Kong citizen was selected as a payload specialist in China's manned space programme, with a chance to become an astronaut to go to space in person, to participate in research and to contribute the country's space programme," Lee said.

Macau's government also issued a statement Tuesday, calling the selection of one of its own "an honour" that sent "a strong inspirational message to the young people of Macau".

The China Manned Space Agency said the decision to select astronauts from the two territories "has garnered strong support and enthusiastic participation from local communities".

Plans for China's "space dream" have been put into overdrive under Chinese President Xi Jinping.

Beijing has heavily invested in its space programme over the past decade, trying to catch up with the United States and Russia after years of belatedly matching their milestones.

The country notched a win this month after its probe carrying samples from the far side of the Moon started its journey back to Earth.

Other achievements included building a space station called Tiangong, or "heavenly palace", as well as landing robotic rovers on Mars and the Moon.

China aims to send a crewed mission to the Moon by 2030 and plans to build a base on the lunar surface.
