Barred from participating in the International Space Station (ISS) by US law, which forbids cooperation in space between the two countries, China has been developing its own LEO capabilities for over a decade now.

It launched its first spacefarers (called taikonauts) in 2003 and 2005 under the Shenzhou program, with a vehicle based on the Russian Soyuz design. A technology sharing agreement with Russia also enabled China to launch their first space station in 2011: a small, single-module space base known as Tiangong-1. A similar platform, Tiangong-2, followed in 2016. Both have since deorbited.
