Chips with curry in Britain would be called, "Asian," not "Chinese."
In the UK, what people refer to Asians, they're thinking of people from the Indian Subcontinent.
Chinese cooking does not utilize curry.
Curry Chicken, a popular Chinese-American dish, is not Chinese related at all. Back in the day, out West, when they were laying the railroad, there was a lot of Chinese cooks. Some Anglo had a batch of curry, and asked if them if they could do something with it, and thus the dish was born.
Chinese spices were imported, and were used by the Chinese, but they tended to a little too exotic for Western tastes. Some were just plain too hot. So the dishes got watered down. Some are even funny, like Chow Mein, which basically meant leftover crap that there was nothing else to do with. In San Francisco during the Gold Rush years, etc, European men not familiar with Chinese food would go to buy something after a hard day's work, and they got served chow mein because they didn't know any better. It was sell it to them or just throw it out. So basically they got served garbage. Out of that mixture, the dish eventually evolved.
The British Empire waged wars over spices in Asia. They killed millions. Over spices. And their food is as bland as bland can get. I have no idea what they did with it, because it sure didn't end up in their dishes.
