I don't think this is due to the 'dominance' of English. The connection between Western and Chinese dragons is probably a lot older and goes back to the earliest contacts during the Middle Ages by European explorers (who weren't English in most cases). Nowadays there's a relatively strict idea in Western fantasy art of what a dragon is supposed to look like, but that's a fairly new development. You make it sound like Chinese dragons not having a separate word in English is somehow a nefarious plot when in reality it's just that people noticed that these creatures are pretty similar and used the same word to describe them. This happens all the time. I would say Westerners are fairly aware that a Chinese dragon is different from a Western one even if the same word is used. I only did a cursory look on Chinese Wikipedia, but it seems like Western dragons are also referred to as 龍 in Mandarin. Is this also forced upon the West due to the dominance of Chinese culture and civilization?
