An unmanned Chinese spacecraft carrying rocks and soil from the Moon returned safely to Earth early Thursday in the first mission in four decades to collect lunar samples, the Xinhua news agency said.
The capsule carrying the samples collected by the Chang'e-5 space probe landed in northern China's Inner Mongolia region, Xinhua said, quoting the China National Space Administration (CNSA).
The agency's director, Zhang Kejian, declared the mission a success, Xinhua said.
With this mission, China became only the third country to have retrieved samples from the Moon, following the United States and the Soviet Union in the 1960s and 1970s.
Beijing is looking to catch up with Washington and Moscow after taking decades to match its rivals' achievements and has poured billions into its military-run space programme.
Chang'e-5, named after a mythical Chinese Moon goddess, landed on the Moon on December 1.

A Canadian astronaut will take part in a lunar mission for the first time in 2023, as part of the NASA-led Artemis project, the minister for innovation, science and industry announced Wednesday.
"I am proud to announce another first: Canada will join the US on the first crewed mission to the Moon since the Apollo mission," the minister, Navdeep Bains, told a press conference.
"This will make Canada only the second country after the US to have an astronaut in deep space."
The mission, Artemis II, will see a crewed test flight sent into orbit in 2023 but will not involve an actual landing on the Moon, according to the US space agency.
