Google AdSense ads in German

I have a website which is available both in English and German.

Now I have Google Adsense setup can someone tell me if it possible to
display German ads when on the German pages. (Still using the same Google Sense account and having English ads for the /EN site)

Does such a feature exist?

Many Thanks,

On some of my German pages, the 'Ads by Google' does appear in German as I have the meta tag: <META HTTP-EQUIV="CONTENT-LANGUAGE" CONTENT="DE">


However, this does not seem to work on the "links" page:
