Since the world is multipolar (the controlling families have different parts of the world carved out to themselves), then both China and Soros can be our enemy and can also be enemies to each other.

The interests of China and Soros clearly derive from differing families whom have determined that naked competition is allowable at this time between them. From both families backing Soros and China respectively, the US is a problem which they desire to eliminate and for which they have plotted methods of destruction for the US which each family prefers.

However, now that one or both families have executed their plans to bring about the destruction of the US, they are looking to remove the competitors that would dillute their spoils of war. Hence the public infighting.
