Samsung, what does that have anything to do with Nexus 5?
And Google is, the last time I checked, an American company.
So China got the iPhone first? Because most of it is made by Foxconn.
Yes, LGE is a Korean company but I think you don't understand the way global trade works.
To the OP, try through the Korean Play store first. I have a Korean bank account and cc so it was easy for me. If not try connecting to Play via a VPN. See if you can have it delivered to an APO FPO or DPO.
