from my understanding, US strategy "for the world" is "you sell me things, I sell you dollars, do democracy or else" - while best China guess seems to be "build business, together, don't push your agenda on others or else" (as with anything, these will change over several decades tho)

but main divide seems to form on "ngo vs government" lines, imo - and ironically the exact opposite way of the proclaimed "authoritarian China vs USAID america" of the previous decade-or-two. (As always, best path is somewhere in the middle between the two)

the main thing that will happen for sure - globalization, unification into bigger and bigger pieces will continue. Sure, big pieces might go further from each other - but smaller ones will will get closer and closer (unless we all die, of course)
