Elon Musk is facing a social media backlash after China complained that its space station was forced to avoid collisions with satellites launched by his Starlink Internet Services project.
The country's space station had two "close encounters" with Starlink satellites this year, Beijing claimed.
The incidents behind the complaints, lodged with the UN's space agency, have not yet been independently verified.
Starlink is a satellite internet network operated by Mr Musk's SpaceX.
Mr Musk is well known in China even as his electric carmaker Tesla comes under growing scrutiny from regulators.
The incidents occurred on 1 July and 21 October, according to a document submitted by China this month to the United Nations Office for Outer Space Affairs.
