Arbitrage and speculation get a bad rap sometimes, but they're incredibly useful.
I'm leaving Ulaanbaatar shortly and I'll be heading to Japan. I went to stock up on some basic supplies - personable consumables and work stuff.
Strikingly, paper is really expensive here for Western-grade, Western-style paper. The local shops literally don't carry it. Instead, they have this checkered sort of paper. It's like graph paper, but with thick black lines. I prefer black ink, and after trying out one of those notebooks, I couldn't read what I'd written.
I tried some of the upscale department stores (Sky Department Store, State Department Store) and there's literally no Western-style, 60 sheet lined notebooks in the $1 to $2 range like you'd see in the USA. They have high end notebooks for $6 to $12, and they have these thin flimsy 20-page booklet-type things for around $1. I settled for the booklet.
Now, if there was the demand to make it worth it, someone importing Western style paper from China at 20 cents a notebook and selling it here for $2 per notebook would be creating a lot of value. If this presented a large enough opportunity, eventually you'd see the margins go down towards cost, as happens in almost all industries.
