It's unlikely to be a problem. Let me quote Google's content guidelines for multi-regional and multilingual sites:
Duplicate content and international sites
Websites that provide content for different regions and in different languages sometimes create content that is the same or similar but available on different URLs. This is generally not a problem as long as the content is for different users in different countries. While we strongly recommend that you provide unique content for each different group of users, we understand that this may not always be possible. There is generally no need to "hide" the duplicates by disallowing crawling in a robots.txt file or by using a "noindex" robots meta tag. However, if you're providing the same content to the same users on different URLs (for instance, if both
example.com/de/ show German language content for users in Germany), you should pick a preferred version and redirect (or use the rel=canonical link element) appropriately. In addition, you should follow the guidelines on rel-alternate-hreflang to make sure that the correct language or regional URL is served to searchers.
You may want to follow the advice given in the last sentence to use
rel=canonical links with the
hreflang attribute, so that Google can easily find the translated versions of your pages and show the appropriate links to users depending on their language preferences.
For example, let's say you had a page in English at
http://www.example.com/page.html and a German version of it at
http://www.beispiel.de/seite.html. Then, in the
<head> section of the English page you can include the tag:
<link rel="alternate" href="http://www.beispiel.de/seite.html" hreflang="de" />
and on the German page you'd include the corresponding tag:
<link rel="alternate" href="http://www.example.com/page.html" hreflang="en" />
That way, Google will know that the pages belong together and are translations of the same content.
