I’m not so sure debris would help take down other satellites in that orbit. The orbit is very low so much of the debris that ends up with a deviation in its orbit will fall down. Even if it doesn’t there’s still air resistance up there which may cause more of the debris to deorbit before jt has time to hit other satellites.

And I doubt China would want to make LEO impossible to move through anyway. It’d affect China badly as well

potentially very dangerous for everyone if they did that. could make it impossible for even them to make a launch. Kessler Syndrome is nothing to toy with.

space is huge and the orbit is low. I'm not so sure debris would be as effective as on higher orbits.

Very expensive to take down 10-100k at once. No one today has that many antisat-capable missiles stockpiled.

Relevant, Chinese domestic media reporting on China's own perspective:

https://www.scmp.com/news/china/science/article/3178939/chin... ("China military must be able to destroy Elon Musk’s Starlink satellites if they threaten national security: scientists" (2022))

> "Researchers call for development of anti-satellite capabilities including ability to track, monitor and disable each craft / The Starlink platform with its thousands of satellites is believed to be indestructible"

"Easy to bring down" vs. "believed to be indestructible"—some tension there!

how though?

Of course it is entirely speculation. But there are previous datapoints you can look at (i.e. iran).
