China enforcing replacement of .com domains with .cn for in-country HTTP traffic

The title seemed a bit misleading at first. “China enforcing replacement of .com domains with .cn for in-country HTTP traffic”.

If I’m reading this thread correctly, China is requiring from at least the op who has some http servers that are publicly accessible to not have a .com domain pointing to their servers but apparently a .cn is acceptable. There is not much information in the thread ion why and whether they need to additionally add a cn tld pointing, is the company needs to just have a cn tld, or if it’s something very specific like the reverse dns needs to resolve the ip to a cn tld. Interesting if legit anyway.
