Sadly I can see the price of these rising to protect the Huawei range.
I suspect you're right, but there's a whole load of Chinese alternatives, many of equal quality. I think the rot sets in when emerging brands establish an expensive UK or EU presence, start puffing themselves up with costly Samsung-style marketing, and trying to price according to what they would like users to pay.
Luckily, given the scale of the Chinese market, and the existence of other countries that will be low-middle income for decades, there won't be a shortage of new challenger brands offering excellent value via the grey market. And the rapid commoditisation of phone tech is going to continue to make the quality of low cost phones better - the one thing that value-conscious buyers need to do is not to have any brand loyalty - that's the main card that supports makers high priced phones.
