>If Chinese industry in general is anything to go by, then a Huawei Dollar buys a lot more work than an Apple Dollar.
Huawei may or may not get more value for money on their R&D spend, but it's not as clear cut as you suppose. Apple have an R&D centre in Shanghai, for starters. And if Apple thought they could do all their R&D cheaply there, they wouldn't have R&D centres in Cambridge and Tel Aviv (I don't know what they do there, but I associate both Cambridge and Israel with silicon chip design).
Conversely, Huawei have eighteen R&D centres in Europe and employ 1500 in research.
EDIT: As far as I can make out, most of Huawei's European R&D is geared more towards 5G and infrastructure than it is handsets.
