Pretty much this. I'm deterred from buying the hang seng because there's a LOT of exposure to Chinese companies, banking sector, etc. I like tencent though, so I just bought that instead. Because tencent is so heavily weighted in the HSI, This is why the tracker has done so well.
Also look at the HSI today. Yes it's done well... But it's only slightly above where it was in 2015. Meanwhile, the US market has performed much better and has more solid companies too.
