This is incorrect. There are lots of ETFs that now directly hold China A shares. CSI 300 index is the equiv of S&P 500 in mainland China. Also, via HK Stock Exchange, you can buy China A shares via "northbound connect". A broker like Interactive Brokers supports this type of trading and the bizarre/special currency (CNH) required for it. That said, I excluded China because it is not developed and has awful transparency.
