The reason I ask those questions is that if I want my asset allocation to include a good chunk of non-US international stocks, I would prefer that to be a broad selection of many different countries. Not just non-Japan Asian countries.
A non-Japan Asian country fund makes me, personally, feel a bit uncomfortable, as I would wonder if this is a fund created in the days of the "Asian Tigers" mindset. It might be a perfectly good fund, but I would want to take a close look at it to see if it felt like a "Flavor of the Month" fund from ten years ago that's still hanging around and taking investments.
Anyhow, if the target date funds include a good balance of US funds, international, and bonds, it might be easiest to just go with one of those whose balance looks good. An ER of .33% isn't horrible.
