Completely agree with everything you say as I thought exactly the same.
It worryingly feels like the very start when covid first emerged with the whole "no reason to panic" "everything will be fine" except this time we should know better and follow other countries in terms of testing/restrictions upon arrival. Personal opinion, the Chinese can't be trusted in terms of sharing information related to covid, that coupled with no restrictions when they have such high case rates is a recipe for disaster (yet again).
