Balance is in the fact that China has NOT moved to invade Taiwan, destroy its infrastucture and murder its citizens.
.. while the US was doing nothing but objecting to their amassing hundreds of thousands of troops and war gear at the Ukrainian border, and lying about it being a "military exercise".
The mere fact that the Ukrainian people expressed their preference for a President that was not a Putin Puppet, was their only "crime".
So you understand why balance is necessary. Of course, China will not destroy Taiwan. It gets its chips from there.
Why US was not doing anything is because they wanted Russia to attack Ukraine, wanted to get Russia involved in a war.
In international politics, one should not do such crimes, because they have their repercussions.
Yeah, China at the moment is not doing anything about Taiwan, but one never knows what will happen in future.
