Yup can. I believe is the band difference. I got the A3010 set, need to flash Oxygen OS.
It's not terribly difficult to flash stock oxygen OS. but in any case, at least for me, the seller claims it already has oxygen OS (playstore etc) installed. If he dun, i'll hold him accountable.
Like what many others have repeatedly said/asked, duno it's A3010 or A3003 (CN/HK). Confirmation I got from seller difference is, CN set = 2 pin DASH charger. It can still be used with an simple $1 adapater but it'll add abit of bulk near your electrical socket.
The other tech specs that might differ due to geo specific hardware might be:
1) LTE bands
2) NFC / android pay full compatibility with local POS machines and singtel NFC sim
3) wifi channels (not G/N/AC) eg. singtel AC router has channels 1-50 or ard that number.
Perhaps bros that have used china sets and are tech pros can share a bit more?
At S$482 (before credit card cashback) is already a steal. compromises...
