Serbia and Bosnia and Herzegovina are the focus of one of the most important Chinese companies’ desire to expand into the Western Balkans. Through the telecommunications company Huawei, China is extending its influence around the world, which is why it has been sanctioned by some countries.

BIRN has researched the company’s goals, the way it is expanding and the consequences of this. We have found out that Huawei paid for trips abroad for ministers.
