This is not "my theory." This is pretty standard historian stuff. It's a combination of cold war shenanigans from the US, globalisation and favourable demographics. You can easily find this by looking at any source that is not pushing a certain political agenda. Here's a pretty good summary that is not particularly tainted: https://moderndiplomacy.eu/2025/06/27/chinas-rise-is-an-exce...

Sorry I have to say that the cited writeup is disappointingly shallow. For example it doesn't explain why other countries with equal or better access to the Western markets didn't all industrialize, so globalization may be necessary but is clearly not sufficient. Also its narrative on Chinese agriculture ignores the fact that Chinese agriculture also developed rapidly both in production and in value of output. It became the largest importer of food because the consumption of protein skyrocketed outpacing almost every other country.
