In addition to WIP -- I was curious, also, and did this Google search:
"inflation-protected securities" +non-us +etf - Google Search
The listing for ETF Trends says this:
5. Non-U.S. Stocks. Remember this works both ways: If inflation does not turn out to be a problem here in the United States and the U.S. dollar actually strengthens versus other currencies, your foreign stock investments will suffer. There are dozens of international ETFs that hold non-U.S. stocks – visit the provider’s page to find out the holdings and decide whether they’re right for you.
A slightly modified Google search found this thread at Boogleheads that has this question somewhere in it (I didn't read it, yet).
