I think you're misparsing the sentence. It just means that this is when it first became known to "western science".
This is about language though. Eurocentrism is about making everything relative to what the west thinks, even when it’s “understanding” is very limited. Like going to explore other cultures and reporting back with authority when there’s plenty of local expertise that should be sourced.
Take the theory of decline of the Ottoman Empire as an example to this type of anti-intellectualism, but there so many mistakes to learn from.
Nice high-brow segue from "you're obviously a Trump supporter" to "civilisation is in decline due to anti-intellectualism", though. Hint: I'm British. Talk about ethnocentrism.
I'm not really sure how I can constructively help you with the sentence in question without literally parsing the tokens for you and identifying the parts of speech, objects, subjects, etc. Seems like that would be a waste of time, given you've already arrived at your own immutable conclusions.
Take for example the Monk Fruit: https://en.wikipedia.org/wiki/Siraitia_grosvenorii
Known in China...but scientific name attributed to the westerner who "found it" in the 1930s.
It's very common if you are cognizant of it.
Chinese does exactly the same thing. I mean, is 盲文 [1] 'yellow' (euch--your terminology) washing? It meets the same standard.
And how about China claiming to have invented high-speed rail, mobile payments and ecommerce? [2] No cries of racism for that one? Strange.
There are many parallel examples.
Edit:
[1] 盲文 lit. blind language aka Braille in English, after its creator.
The same standard would be if China took the word "Braille" and then in Chinese, it is named after the first Chinese person who read Braille.
If you think English speakers have an easy time saying "Siraitia grosvenorii", the scientific name, named after the "discover" Grosvenor, then you have some serious delusions.
