It is the latest mission in Beijing's space programme that aims to send astronauts to the Moon by 2030.

The crew took off on a spaceship on top of a Long March-2F rocket form the Jiuquan Satellite Launch centre in China's northwest at 8:59 pm local time (1259 GMT).

The mission is led by Ye Guangfu, a fighter pilot and astronaut who was previously part of the Shenzhou-13 crew in 2021.

He is joined by astronauts Li Cong and Li Guangsu, who are heading into space for the first time.

They plan to stay at the Tiangong space station for six months.

While there they plan to carry out experiments "in the fields of basic physics in microgravity, space material science, space life science, space medicine and space technology", the China Manned Space Agency has said.

The new crew will replace the Shenzhou-17 team, who were sent to the station in October.

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

The world's second-largest economy has pumped billions of dollars into its military-run space programme in an effort to catch up with the United States and Russia.

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

China has been effectively excluded from the International Space Station since 2011, when the United States banned NASA from engaging with the country -- pushing Beijing to develop its own orbital outpost.
