I used to have three China funds: Greater China Fund, TDF and the FXI. The first two are closed and FXI is an ETF. I sold the first some time ago because of high expenses, and now I'm narrowing down to FXI.
Isn't FXI expense ratio (ER) also quite high Adam (0.72% ?)
Perhaps have a look at investing a third of the amount in YINN (3x ETF with ER 0.95%) as you would have in FXI - and the other two-thirds in TIP (ER 0.2%). That would reduce the overall ER down to around 0.45%
Rebalance back to 33/67 weightings once each year (or whenever a AIM trade occurs) and you'll generally track the underlying.
