Change Galaxy A3 from Chinese to Europena/Dutch

I had to buy a new phone while being in China: Samsung Galaxy A3 SM-A3000 upgraded with Android 5.0.2. However, due chinese policy, several sdervices from Google like Play Store and Play services are not installed. I have tried to add the APKs but thgat does not work.

How can I get a European (English or Dutch) version on my smartphone that also included Play Store, Gmail and accept my Google account?

Kind regards
