To me it is very clear. It is the Invention of the Guttemberg mobile type printing press and the sharing of knowledge it created. Latin has over 70 different writing symbols(Upper and lower case plus numbers), Chinese has thousands.
Printing a book in Chinese was orders of magnitude more work(and expensive). Remember that at the time it took years to copy a book. Chinese already knew about printing presses, but Guttemberg discovered the way to make it in metal, and making new Glyphs from molds is very inexpensive thanks to latin.
After Guttemberg it took years to copy a book, but once you have it you could make thousands of copies. Chinese could not, because the plates deteriorated fast and was very expensive to recreate them. The Japanese identified the problem and created a vocalic language from Chinese, the kana. The reason Japanese stated running circles around Chinese and humiliated them.(Chinese and Japanese hate each other so much)
The fact that Chinese today consider Confucius the "greatest philosopher of all time" is the evidence of Chinese lag.
Imagine Europeans considering only Aristotle or Plato, with no mention of Descartes, Kant, Nietze, Ortega and dozens of other brilliant philosophers.
Renaissance and science were the result of the printing press. Everybody could buy a Bible, and discuss it, without having intermediaries.
Before that a Bible or any other book was priced as years of the salary of a worker.
