In English, "No wonder" is used almost exclusively in same context. For example: "You live in China, no wonder you can speak Mandarin". In this case most appropriate to use word "конечно" ("of course"): "Вы живете в Китае, конечно Вы говорите по китайски". "Неудивительно", as others suggested, is also sensible translation, but in this case you have to add "что": "... неудивительно что Вы говорите по китайски".

no wonder in russian is - Неудивительно,

You live in China, no wonder you can speak Mandarin - the better translation is "Вы живете в Китае, поэтому неудивительно, что Вы говорите по китайски"

please write the whole phrase. Wonder may have different translation. не удивительно, не чудо, не гадай

неудивительно. But it depends on the context. It could be used as adective and as adverd.
