Is there a way to localize more languages in English?

I explain.

My app is localized in Italian and English. Is there a way to localize all the other languages (except italian) in english?

If my app will be downloaded by a guy in开发者_C百科 China for example, i want him to display my app in English.

Any suggestions are welcome.

That will be done by default, as long as English is your default language, when the application doesn't find a properties file for any other language it will default to English.

In this case it will default to English, for every language but Italian.
