After omicron China's response doesn't really make sense at all. It is much more contagious than the previous strains, but it's milder. China seriously should reconsider it's zero covid policy, like the rest of the world is doing. Even Australia did that and opened their borders for foreigners in the end.
Here in Norway everything is back to 2019 , all corona related t restrictons have ended (that includes international travel) which means that if you could enter Norway pre march 2020 you can do it now without any restrictions like testing etc. There are still people dying of course of covid 19 but the median age has rised from 85 to 86 which is an age range many people die anyway.

Anyway I hope China somewhere in the future allows for international travel, but it doesn't seem to happen any time soon with the strict zero covid 19 policy they have in place.
