Have a situation where more of East Asia is First World in standards of living. And thus Eurasia becomes like buttressed on two ends by (more) wealthy nations.
Points if it isn't a "KMT wins Chinese Civil War therefore all of China becomes Taiwan standards of living LOL" scenario.
Don't forget SE Asia as well.
Points also if you consider more of the Pacific Rim, like having the Oceanian island statelets get more developed.
