It may be the top trading partner, but among those it counts no friends and no allies.
In terms of international relations, nations don’t have “friends”, but rather, interests. The Soviet Union was an ally in WWII, not a friend. Germany, Japan, and Italy were once enemies and now they are allies.
The point is that China’s influence and power can control the actions of many of these countries. Do you thin that Biden will issue some sort of apology to Xi for calling him a dictator? Why did Biden call the Chinese spy balloon unintentional, of course, and that Xi was not aware of it. Do you believe that? Or does the $30 million the Chinese gave to the Biden Crime Family influence Biden’s utterances.
