We all "opened up" because there's clear and transparent data on the dominant omicron strain, and we know what it is capable of, and that it's not necessary to control it.

We cannot say the same about the situation in China now because we do not know for sure whether there are new dangerous variants that are unreported.

This isn't asking for much, simply report your data like everyone else and let the world knows it's just the standard omicron variant, and let the world study the numerous new subtype that has been founded in China now so that we know they are not any more dangerous than the regular omicron. Then we can all be safe.

This isn't something strange to ask, this is what the rest of the world had been doing, and that's how we discovered variants like Beta, Delta, Omicron, etc.
