The Chinese government is implementing a wide series of measures to reduce the amount of debris left in orbit by Chinese rockets and satellites, and to develop a space-surveillance tool to determine what is in orbit, Chinese space-debris experts said.

The measures, some of which already have been put into place, include techniques already adopted by some other space powers to reorbit retired satellites out of the geostationary orbital arc and to render Chinese rocket upper stages passive in orbit by emptying their fuel tanks to prevent the threat of explosion and debris propagation.

The Chinese government has been a member of the 11-member Inter-Agency Space Debris Coordination Committee (IADC) since the mid-1990s. But Chinese officials concede they have been slow in adopting debris-prevention or debris-mitigation measures.
