I don't think it's that much of an outrageous claim, plenty of our fellow countrymen works at local regional branches and English wings of China-owned companies these days. It doesn't take much stretch from there to imagine some of them moving to near their HQ.

It's annoying that sometimes people thinks there has to be basic mutual intelligibility between Chinese and Japanese languages against the reality that there's none, but this is not about that at all. Chill.
