In Europe, there are a number of partnership sites for B2B as you're implying. You could use these sites to post your offer or search for other offers and hopefully make a match.

Another approach is considering hiring local distributors who specialize in your industry. The advantage here is local distributors will already have a strong network to promote your products/services. Furthermore, local distributors would have thorough understanding of the local market,language, and business culture to close deals.

If you find my answer helpful, I'd be happy to give you straight to the point call on how to find local distributors.

Cheers!
