The CCP has it's hooks into a lot of international organizations. They are completely self-interested but use their propaganda machinery to shift focus to everywhere but on them. They tried to blame the US military for starting the outbreak, then switched their focus to calling for cooperation and avoiding finger-pointing and blame. What they really want is everyone to forget that they are to blame, and try to shame other countries into "cooperation", meaning doing the CCP's bidding.
The WHO put out a statement saying they regret the US's decision to defund them. Not that they regret being the CCP's pawn and for helping create the pandemic. They're trying to shift focus off their ineptitude by trying to make people think the US is making a bad decision by defunding them. It's one of the best decisions we could make right now.
The next best decision will be to start ramping up our own manufacturing, and improving trade deals with non-communist run countries with whom we have shared goals. Then getting as many other countries together to impose heavy sanctions against China until their citizenry have no choice but to revolt against the CCP.
