Are you talking about the West in general because NATO is specifically an anti-Russian military alliance
What NATO is de jure is irrelevant. De facto it is far from being 'specifically an anti-Russian military alliance'. I am going to remind you that it is the same gang of states that recently invaded Iraq and Afghanistan, which make sure that the genocidal project of Pissrael is completed, etc. Among other things, it is the same gang of states that is trying to make the PRC submit to it as a neo-colony.
What does NATO have to do with China?
Literally the enemy of the PRC today.
NATO is first and foremost about containing Russia
NATO is first and foremost a white supremacist organisation that has the maintenance and strengthening of colonial relations between itself and the rest of the world.
Their strength or lack thereof isn't immediately relevant to China
If you completely ignore their efforts to hurt and exploit the PRC, sure.
The West's strategy for containing China is through the three island chains (Taiwan, Okinawa, Japan, the Philippines, Australia, New Zealand)
Cool. And who's doing that? Is it not the gang of the usual suspects?
