But...
I haven't seen any credible claims of how Chinese was actually "westernized" aside of Chinese writers seemingly randomly pointing fingers and blaming European influence for a change of style initiated by the younger generation.
Even your example shouldn't convince anyone, since in English we don't say "do improvement", and generally English doesn't overuse "do <noun>" much.
I've read an attempt to connect the dots here: https://news.mingpao.com/ins/%E6%96%87%E6%91%98/article/2017...
Which was ridiculous if you read carefully, and I've gleefully written an article shredding it apart -- https://hnfong.github.io/public-crap/writings/2020/%E7%A9%B6...
Joan Pinkham wrote a book titled The Translator's Guide to Chinglish[1]. It's a fun book to read and really teaches native Chinese speakers how to write good English. Interestingly, a lot of the lessons in that book can be applied to Chinese writing too, such as avoiding nounification, and removing duplication. For instance, just say "dislike" instead of "to have a dislike for". And instead of saying "give guidance to", just say "guide".

Or it occurred at a time when literacy rates massively increased, and thus there was some vulgarization of the language to some extent.
I think he explains how to write better Chinese pretty well, I just don't think pointing fingers at other languages is helpful especially if it isn't grounded in fact or evidence.
Common claims are often common for reasons...
