I'm pretty sure all cultures adapt and learn from other cultures. That's just how human culture develops. Vietnamese takes on French favourites resulted in bahn mi and Vietnamese coffee, both of which are very good. Poor Hongkongers wanting to eat like Brits resulted in Hong Kong's famously weird "Cha chaan teng" food and Hong Kong-style milk tea. And, of course, Europeans went crazy over Mesoamerican chocolate and created a cornucopia of confectionery products made from the cacao bean.
