Not at all, but it requires a 20th Century pretty different,
Your challenge, should you choose to accept it, is to come up with an ATL where China regains its historical place as the world's largest economy (with the largest GDP, by PPP) by the present day, with a POD after 1900. So the Boxer War may still potentially be averted; perhaps if the Empress Dowager Cixi had been inclined to change her long policy of suppressing the Boxers, easing the pressure by legitimizing them and preventing the whole situation from exploding like a powder keg. That way, might it have been plausible to prevent the fall of the Qing Dynasty, and China's descent into the warlord era in the 1900's? And even if it had, could it have potentially been capable of achieving the desired result (averting the rise to power of the Communists in China, and enabling them to pull off their own Meiji Restoration, as proposed by Yuan Shikai in “Principles for a Constitution”)? After all, China does have the largest population of any nation on earth by some margin, with a population of over 1.5 billion people; surely it's not too much of a stretch for it to have the largest economy as well?
Is it a stretch?
Not at all, but it requires a 20th Century pretty different, in terms of great power politics, than what came about historically...
And a different China, as well; the issue that strikes me immediately is that while Japan pulled off industrialization, that effort also led, ultimately, to Japan's attempt at hegemony in northeastern Asia and the Western Pacific, which was destined to fail, for a variety of reasons...
But it also shows that Japan, a centralized archipelago that did not offer a whole lot to entice overt European intervention, was able to adapt to Wesern technology and organization, in part because Japan is - in comparison with China - fairly small, both in population and territory.
Lot more challenging to bring a huge continental nation, with its share of ethnic and cultural divides, into the "Western World" in the same period.
One thing I have always thought is that a (relatively) smaller "China" might have had a better shot at modernization in the Nineteenth Century than a nation state with China's historical borders, from Central Asia to the Pacific ... certainly would be easier and cheaper to focus on certain regions (presumably the historic heartlands) in terms of internal development, infrastructure, educaton, political reform, etc.
Best,
