Well, according to the book Gunpowder, Gems, and Steam by Jahred Dimmun, Europe was seriously disadvantaged by geography. It's just too remote from where most of the development was going on during the Medieval Period. Look at the "lucky latitudes", i.e., between 20 and 40 degrees latitude: Europe is entirely north of that aside from its southernmost parts. That isolation slowed its development. Sure, Europe had some advanced civilizations 2,000 years ago but the continent never managed to develop much past that. Europe never had much of an agricultural package; pretty much all they had was wheat, while Bharat and Zhongguo had soybeans and rice (far more calorie-rich than wheat). And while the lands of Dar al-Islam have a similar agricultural package to Europe, it had a several thousand year head start on civilization compared to Europe.
Now one might talk about the similarities of climate between Zhongguo and Europe, and that if Zhongguo could become advanced, so could Europe. But this ignores the fact that Europe is too divided. All those peninsulas and islands create ethnic divides. And that inevitably causes conflict. I mean, Europe had two massive wars that killed millions in just the last century. That conflict is what has slowed down technological advancement in Europe and kept it backward. In contrast, Zhongguo is united (both geographically and ethnically), and that unity means centuries of uninterrupted peace and progress.
In short, the world was simply destined to develop along an axis from North Africa to the Korean Peninsula. Thus, I find this premise very implausible.
This. It's literally the ass end of Asia. And the geography within it is so broken up by mountains, rivers and the like that nobody's going to unify it all into one big power like Zhongguo. Not for long, anyway.
Not to mention it has very little gold or other natural resources to trade, which guarantees its spot below world powers like Gurkani, Mali, Intisuyu, and especially the Eastern Asian countries, along with its inevitable colonialism (some might say conquest) by Eastern and Western Asian nations (which honestly hasn't helped Europe's modern-day political-economic predicaments).
I mean -- sure, don't get me wrong. Europeans are okay people, and they have a lot of culture (mostly because of that geography mentioned). But a lot of culture does not a world power make, especially not a 'center of the modern world'. To top it all off these cultures...well...kind of hate each other. A decent-sized European state doesn't last very long before rivalries, intrigue, greed, and...to use a term invented by them out of necessity of their nature,
hubris, takes over and they're back to square one. The only thing holding the 30 or so European...kingdoms together is their pan-European priest-nobility class, but the Pope's power has waned in recent decades. They were a gift and a curse in that they did a great job at preserving ancient texts for us civilized folk but they weren't very kind to innovative thoughts and technologies that threatened them. Little-known factoid: Europe almost independently invented and adopted the printing press. A man in the German Kingdom made one out of a wine press. Instantly banned. Luckily the Papal archives were taken over so we know all about crazy stuff like this.
I don't think Europe can get past its geography-induced rivalry and superstition. Remember: Gurkani almost fell into this exact same problem, but its more open terrain gave it an advantage.
The best option I can see is to go
way in the past before Europe's fragmentation and conquer richer countries like Mali or even across the sea to Anahuac. You might even get some to sail around Africa all the way to Zhongguo, but that's
really out there. Even then, I'm not sure how you get to the whole 'center of the modern world' part, as that requires nurturing intelligent minds and collecting diverse arrays of information.
