I don't understand the point of this thread. If xiaomi does officially launch in Pakistan, you will see its tv ads, advertisements on roads etc. They will launch with official stores and places where you could claim warranty etc.
In the meanwhile you guys can get phones from xiaomipakistan which is not official in a sense that they wont offer warranty but would provide you with legit phone. You can get cash on delivery, and verify the box using mi.com/verify website.
Or you guys can check olx where there are plenty of people who have imported the phones and are selling them box packed for an inflated price. You will get the phone with box packed and open at your end.
I myself bought a Redmi note 3, 3GB edition from olx for 18k in Oct. I don't see any problem with buying stuff from there or xiaomipakistan or any reseller.
