The huge amount of space debris that China has, was created when they tested an anti satellite weapon on one of their dysfunctional satellites in 2007.
Well, so long as they weren't "testing" it on someone else's functional satellites... that would be bad. (Or maybe they did, and we don't know about it. And the bulk of that Chinese space debris is what's left of their anti-satellite platform.)
