It dismissed as a "Western exaggeration" for fears that the rocket wreckage that China launched to build its own space station could fall to Earth.
The state-run Global Times reported on the 6th, citing space experts, saying that there is no need to worry because the possibility of rocket debris falling into the pollution is very high.
"Most debris will burn while entering the atmosphere and only a small fraction will fall to the ground," said Wang Yanan, editor-in-chief of Aerospace Magazine's'Aerospace Knowledge'.
He added that the crash of rocket wreckage is a problem that the Chinese space authorities have considered carefully at every stage, from the design stage of the rocket to the launch point, and the rocket launch attitude and trajectory.
"This is some western exaggeration of China's space technology advancement," he said. "It's an old strategy that adversaries use whenever China's technology advances."
China launched Changjeong 5B carrying Tianhe, a key module, for the construction of a space station on the 29th of last month, but observations have been raised that it is descending toward the Earth because it is not properly controlled.
