Royal canin Junior 33 question

I am needing to get Kitzel off Eukanuba kibble (breeder started) and am looking at RC Junior 33---does anyone use this? I have written to the UK office 3 times to try and determine if it contains any products or by-products originating in China---yet w/out success. I have the package which comes from the EU but does not give me any origin of country. I am also considering Exclusion from Italy (I am limited here in what I can get) and have written to them but as yet no answer. Any advice appreciated.
