Prime Minister Wen Jiabao watched the docking at Beijing's Aerospace Control Center along with other top communist party officials, Xinhua said.
Shenzhou-8 blasted off on November 1 from a launch facility in the Gobi Desert in northwest China -- one month after the first space laboratory module Tiangong-1 was launched into space.
According to Wu, the two modules will fly together for 12 days before conducting another docking test. The docked spacecraft will then fly for two more days before separating from each other.
Shenzhou-8 is scheduled to return to Earth on November 17, while Tiangong-1 will remain in space to wait for the next docking test.
"Achieving the space rendezvous and docking is another historic technical breakthrough for China's manned spacecraft project," said Wu.
China sent its first astronaut into space in 2003, the first stage in a "three-step" strategy to develop its manned engineering project. The launch of the Tiangong-1 lab module is the second step. If successful, it will be followed by the last phase: to build a permanent space lab that will allow astronauts to conduct long-term space experiments.
