Here in Vietnam it's completely impossible to get pseudoephedrine at all and I think it's the same in all Asian countries. I even resorted to trying to buy some ephedra tea (Chinese medicinal herb from which ephedrine was first discovered). I ordered a box of tea bags from Shopee.vn and rather amusingly received an envelope with the amount I had paid including shipping in cash and an apology letter saying they could no longer sell this herb and please don't leave a bad review.
However, a few months earlier due to a Google translate mixup where I thought I was ordering peppermint oil, I got 100ml of sassafras oil [0]. It's a precursor to MDMA and at least as restricted as pseudoephedrine.
