As long as China is a non-interventionist country, none of what you suggest is possible.
At most, all China can do is invest in local talent to reduce its dependence on Western technology and avoid major damage in the event of widespread sanctions across the economy, such as those in the semiconductor sector.
China does not have the soft power to use its media to install an anti-US regime in South Korea and Japan. And the war in Europe has only accelerated the number of European and Russian talents going to work in the US and escaping the European decline.
And on top of that, with Russia and NATO moving towards a stalemate agreement on Ukraine, China will not be able to count on Russia's M.A.D. power when the US focuses on Asia with Trump.
With the agreement in force, Russia will only be officially neutral at best, selling oil and wheat to all sides, but without involving its military and nuclear force in Asia.
