I think it's really important to consider where you'll be touring. Is it going to be on paved roads, or in udeveloped/developing countries with lots of dirt and potholes? I read a book by a guy (can't remember who or the name of the book, I'll try to dig it up) who said that when he was touring in Mongolia and N. China a Mountain Bike was the only way to go. If you think the bike's going to take a beating, get wheels and tires that can take a beating. From what it sounds like, if you're touring in Asia, this should be of serious importance to you. The two bikes you linked to are good, comfortable looking models that can probably hold weight well (not having ridden either myself) but I'd be worried about the wheels and tires in certain circumstances.
