I dont know the figures but from what I pick up from Phills and the news many other non white foreigners are also quite likely to be attacked or at risk.

Over the 5 years or so of taking notice of events in Phill there does seem to be a lot of Koreans and Chinese also robbed violently and sometimes killed but they dont come on to the radar in most Brit media sites.
I know in the Wifes local town over the years many Korean and Chinese business people have died as the result of robbery or possible kidnappings often it seems

It will be interesting how the Authorities deal with the present investigations I did read a couple of phills on FB writing how it appears often after elections and major changes in leadership national and local level "agreements especially at local level alter"
