You're very welcome! -- and I appreciate the kind words.
Past several years, concerns over orbital debris have multiplied greatly, perhaps exponentially. In the almost seven years during which I've been working toward an advanced degree in pertinent legal subject matters, "Debris" with a purposeful capital-D has been always in the top three issues in space law and policy. (If it's an interest of yours, PM me if you want cites to sources and so on.)
And just to keep the pot boiling, there are some indications that the China rocket was on a trajectory after launch which took it unusually close to the ISS. Different "mavens" on orbital dynamics and parameters, launch sequences and procedures, and tracking of space objects were tossing the issue of deliberateness or intent around earlier today. Former NASA Administrator Bridenstine remarked on this today, in a webinar on issues in national security (U.S.) space. What the various, several mathematical factors prove, infer, suggest or otherwise prompt as further questions, I'm not commenting (as it's way outside my subject matter lanes).

What doesn't seem to be beyond doubt is that none of the ISS partners were given any warnings or a heads up about any possible conflict.

Chinese massive Chang Zheng 5 (CZ-5) rocket flew once again.
Liftoff of the Yaogan 41 mission took place on Friday, Dec. 15, at 13:41 UTC from Wenchang, the usual launch site for the CZ-5. The payload was described as a remote sensing satellite, which would operate in a high orbit. It was tracked in a standard geostationary transfer orbit after launch.
The fairing of the rocket seems to be extended compared to previous missions, which indicates a large payload inside. The mass could be in the range of 10,000 kilograms or more, given the capability of the rocket which is the most powerful in China’s current fleet.
Chang Zheng 5 is a heavy-lift rocket, used only for missions where China requires its performance to deploy heavy payloads or reach high-energy trajectories. It stands 57 meters toll, with a liftoff thrust of 10,565 kilonewtons. It can place up to 32,000 kilograms of payload into LEO, and up to 14,000 kilograms into GTO.
The official purpose of the Yaogan 41 is stated as “Land Surveying, survey of crops, environment control, meteorology alert, and general disaster prevention and mitigation” which is most likely a placeholder for its true mission.
