China has launched its first extraterrestrial landing craft into orbit en route for the moon, a major milestone for its space programme.

The Chang'e-3 lunar probe, which includes the Yutu or Jade Rabbit buggy, blasted off on board an enhanced Long March-3Bcarrier rocket from the Xichang Satellite Launch Centre in China's southwestern Sichuan province.

President Xi Jinping has said he wants China to establish itself as a space superpower and the mission has inspired pride in China's growing technological prowess.

State television showed a live broadcast of the rocket lifting off.

If all goes smoothly, the rover will conduct geological surveys and search for natural resources after the probe touches down on the moon in mid-December as China's first spacecraft to make a soft landing beyond Earth.

"The probe has already entered the designated orbit," the official Xinhua news agency quoted Zhang Zhenzhong, director of the launch centre, as saying.

"I now announce the launch was successful.

"We will strive for our space dream as part of the Chinese dream of national rejuvenation."

In 2007, China launched its first moon orbiter, the Chang'e-1 - named after a lunar goddess - which took images of the surface and analysed the distribution of elements.

The lunar buggy was named the Jade Rabbit in a public vote, a folkloric reference to the goddess's pet.

Chinese scientists have discussed the possibility of sending a human to the moon sometime after 2020.

In China's latest manned space mission in June, three astronauts spent 15 days in orbit and docked with an experimental space laboratory, part of China's quest to build a working space station by 2020.

If the lunar mission is successful, China will become the third country, after the United States and the former Soviet Union, to soft-land on the moon.

But it is still far from catching up with the established space superpowers, whose moon landings date back more than four decades.

China is looking to land a probe on the moon, release a moon rover and return the probe to the Earth in 2017, Xinhua said.

China insists its space programme is for peaceful purposes, but the US Department of Defence has made clear it wants to prevent China's increasing space capabilities giving it any strategic advantage.

China said it will share the technological achievements of its manned space programme with other nations, especially developing ones, and will offer to train astronauts from other countries.
