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.
SpaceX has already launched almost 1,900 satellites as part of the Starlink network, and plans to deploy thousands more.
Last month, the US space agency Nasa abruptly postponed a spacewalk from the International Space Station over concerns about space debris.
