we need traffic lights for satellites

iMo:
You have to build a space station equipped with powerful CW lasers, flying above the main debris belt, shooting at the debris from above to force them down to de-orbit and burn in atmosphere.
All systems have been designed in detail in Pres. Reagan's "SDI program" (1983) already..

And frankly Chinese can go fuck themselves with those accusations. https://en.wikipedia.org/wiki/2007_Chinese_anti-satellite_missile_test

--- Quote ---The 2007 Chinese ASAT test was the second largest creation of space debris in history after Project West Ford, with more than 2,000 pieces of trackable size (golf ball size and larger) officially catalogued in the immediate aftermath, and an estimated 150,000 debris particles.[27][28] As of October 2016, a total of 3,438 pieces of debris had been detected, with 571 decayed and 2,867 still in orbit nine years after the incident.[29]

More than half of the tracked debris orbits the Earth with a mean altitude above 850 kilometres (530 mi), so they would likely remain in orbit for decades or centuries.[30] Based on 2009 and 2013 calculations of solar flux, the NASA Orbital Debris Program Office estimated that around 30% of the larger-than-10-centimeter (3.9 in) debris would still be in orbit in 2035.[31]

In April 2011, debris from the Chinese test passed 6 kilometres (3.7 mi) away from the International Space Station.[32]

As of April 2019, 3000 of the 10,000 pieces of space debris routinely tracked by the US Military as a threat to the International Space Station were known to have originated from the 2007 satellite shoot down.[33]

Not to forget they don't care where the booster rockets come back down to crash... until I guess when it will fall on someone.

Sure, it shows their ass is not clean, but in the end, it shows that orbital space contamination and congestion are quickly becoming a problem. And it also likely to create possibly severe international tensions.
