Backlinks from pages in different languages

I have an US site, written in English. I hired someone to build high pr back links. I read his report, and many
of the posts were comments on do -follow articles written in English- on pages written in other languages (Polish, Italian, Chinese, etc.).
Is there anything to be worried about here? Will these factor in ranking me on US Google?
Thanks

It generally doesn't matter where your links come from. However, if they are contextual links it's better if they are surrounded by text in the same language. For a blog comment I wouldn't worry to much about it.

Hi Do you think that the direct translation of the keyword would be good to? As this would seem alot more natural to google and diverify you backlinks?
