Non english Websites and blackhat seo

The question is this. When doing seo you know two things, you need good content and you need backlinks. We know diffrent techniques get backlinks to our sites. But do these backlinks need to be in webs with same language?

May you use AMR to submit 100s of articles, this articles will be posted in article directories. Should the articles be written on what language? will the links to non english websites count?

Will Bookmarking demon be usefull to sumit to these sites? will the description and data need to be written in english, although the sites to submit are on non english languages?

Please advice.

I would like to know this aswell?

Of Course, just use the anchor text in your language, but write and submit the articles in english. The Links still count!
