How to get a phone from China?

I'm interested to get a phone (Xiaomi Mi Note) from China, which is not / not easily / not at a reasonable price available in Vietnam (or elsewhere, like HK, BKK, SP) yet.
Any advise on how to do that?
- Do I find someone who travels from Hanoi to a major city in China and brings back one?
- Is there a Vietnamese company one could engage for such service?
- Any experience with Chinese companies shipping to Vietnam (alibaba, aliexpress, taobao etc) and Vietnamese customs?
I don't mind paying a reasonable (+25% of the price in China?) premium or fee.

Any advise/ help would be appreciated.

thank you so much !! I really appreciate it!!

Our company has physical presence in China.

I may be of assistance. PM me if you require.
