Beijing, Jul 5 (IANS): China has rejected claims by the US space chief that Beijing might be contemplating a "takeover" of the Moon as part of its military space program, and accused Washington of seeking to turn space into a "warfighting domain".

NASA Administrator Bill Nelson told German newspaper Bild in an interview that the world must "must be very concerned" about China potentially "landing on the moon and saying, 'it's ours now and you stay out'".

Chinese Foreign Ministry spokesman Zhao Lijian responded to the accusations on Monday, saying that this was "not the first time that the head of the US National Aeronautics and Space Administration has ignored the facts and spoken irresponsibly about China".

"The US side has constantly constructed a smear campaign against China's normal and reasonable outer space endeavours, and China firmly opposes such irresponsible remarks," he added, claiming that China has always stood against weaponisation and promoted a shared future of humanity in outer space, RT reported.

When asked to clarify what military purposes China could be pursuing in space, Nelson said that Chinese astronauts are learning how to destroy other countries' satellites, and claimed that the competition for the south pole of the Moon would be especially intense.

He also said that by 2035 Beijing might finish construction of its own Moon station and start experiments a year later.
