I wish they’d drop that “Asian” lingo. Makes it sound like Chinatown is raping and pillaging.
“Asian” in UK, not unreasonably, is generally used to refer to the largest group of immigrants from the continent of Asia, who are from South Asia: Pakistan, Bangladesh and India.
The same term in USA, equally reasonably, is used to refer to our largest group of immigrants from that continent, East Asians: Chinese, Japanese, Vietnamese, etc.
The term just means different things in the two countries.
