Heya. I actually have no clue what these are, but...
Generally speaking, foreign language products are not considered canon, because they're not developed in conjunction with CGL. And often, foreign language stuff is... Questionable. Mainly because the companies put their own spin on things.
With FASA, the only foeign language product that became Canon was the original Germany Sourcebook, which was mostly a translation of a book put out by the German publisher (Which I think was the original German FanPro company). However, it was also edited a bit, partly to trim it down into a "normal" sized FASA sourcebook, and partly because some of the gear was apparently a bit over the top.
When FanPro Germany acquired the license from WizKids after FASA closed, there was a lot more communication between FP Germany and FP US. As such, the material released then (by FP Germany) was generally considered canon. Nothing outside of that was though.
Since then though, we're back to non-canon.
However at least summaries of these products would be very interesting.

And of course, if you can read the books and like what you see, you're always free to incorporate them into your home game
