Personally, I have $BABA and $1211 as China shares in my portfolio, which is enough for me. Outside of the All World ETF, I try to avoid all the garbage that is always included in ETFs.
Since I'm a long holder, I'm convinced of BYD in the long term and the stock is coming back significantly anyway, I would personally still buy now - but of course no investment advice 😅 It may be that I buy again soon...
