I hope they become better at injecting payloads into low orbit. The higher orbits Chinese companies use for internet constellations right now have huge risks of space debris, since satellites will take hundreds of years to fall out of orbit.
Those are orbits with 100+ year dynamic lifetimes (as is regularly discussed, i.e. ref [d]). It's true that they could actively deorbit them; that's the lifespan of passive debris that fails to actively deorbit. (Ref [d] also discusses spent rocket stages in this context, and China's uniquely bad behavior there).
I assume the main motive behind this is basic business economics. China doesn't have reusable boosters; the ones that might succeed this month won't reach Falcon 9 levels of mass production, and launch cadence, for several years. They're on an expensive on-ramp. To a first-order simplification 1,100 km orbits need only 1/4th as many satellites for the same coverage as 550 km orbits.
