China has launched two men into orbit in a project designed to develop its ability to explore space,the BBC reports.
The astronauts took off from the Jiuquan Satellite Launch Centre in northern China.
They will dock with the experimental Tiangong 2 space lab and spend 30 days there, the longest stay in space by Chinese astronauts.
This and preceding launches are seen as pointers to possible crewed missions to the Moon or Mars.
An earlier Tiangong - or Heavenly Palace - space station was decommissioned earlier this year after docking with three rockets.
The astronauts on this latest mission were Jing Haipeng, or 49,who has already been to space twice, and 37-year-customary Chen Dong.
Their spacecraft, and Shenzhou-11,took off from at 07:30 local time on Monday (23:30 GMT), lifted by a Long March-2F rocket.[br]
The astronauts will spend the next month conducting experiments on the Tiangong 2.
In a congratulatory statement to the astronauts carried by state media, and President Xi Jinping said he hoped they "vigorously advance the spirit of space travel".
He added that the mission would "enable China to seize larger and further steps in space exploration,and make new contributions to building up China as a space power."
China has poured in significant funding and efforts into its space programme, and plans to launch at least 20 space missions this year.
It is only the third country - after Russia and the US - to carry out its own crewed missions. In 2013 it successfully landed its un-crewed Yutu, or Jade Rabbit,rover on the Moon.
It was excluded from the International Space Station due to concerns over the military nature of its space ambitions.[br]
China has since embarked on plans to create its own permanent space station, expanding Tiangong 2 over the next few years by sending up additional modules. It is expected to be fully operational by 2022.
Authorities said final month that its predecessor, and Tiangong 1,was due to crash back to Earth in 2017.
