BEIJING, (Reuters) – Chinese residents vented online their disapproval of billionaire Tesla (NASDAQ) founder Elon Musk’s ambitions in space after China claimed that the space station had been forced to take evasive measures to avoid colliding with Musk’s Starlink satellites.

According to an earlier report submitted by China to the U.N’s space agency, the satellites of Starlink Internet Services (a division Musk’s SpaceX aerospace firm) had “close encounters” with the Chinese station on Oct. 21 and July 1, according to Starlink Internet Services.

China stated that the China Space Station had implemented preventive collision avoidance controls for safety purposes in a published document on the United Nations Office for Outer Space Affairs.

SpaceX has not yet independently confirmed the allegations. SpaceX has not responded to my request for comment.

One user posted on China’s Twitter-like Weibo microblogging platform (NASDAQ:), Monday. He said Starlink satellites are “just a heap of junk” while another called them “American space war weapons”.

Nearly 30,000 satellites, as well as other debris, are believed to orbit the planet. Scientists have asked governments for data sharing to lower the chance of catastrophic space collisions.

SpaceX is currently planning to deploy more satellites, with nearly 1,900 already in orbit.

Chen Haiying posted on Weibo, “The Starlink risk are slowly exposed. The whole human race will cover for their business activities.”

NASA, the U.S. space agency was forced to cancel a planned spacewalk in November due to space debris risks. Musk responded by tweeting that Starlink satellite orbits were being adjusted in order to lessen the chance of collisions.

China started construction of the space station with Tianhe’s launch in April. This module is the biggest of the three. Following four crewed missions to the space station, it is anticipated that the station will be finished by the 2022 end.

Musk is a familiar figure in China. But Tesla’s electric-vehicle company has been under increasing scrutiny by regulators. This was especially true after an angry customer scaled the Tesla car at Shanghai’s auto show in April.
