These are translated into Russian texts in the domain of international politics obtained from foreign authoritative sources. The collected articles contain both the author's opinion on the subject matter of the article and a large number of references mentioned between the participants of the described situations. The dataset contains 73 large analytical texts, labeled with about 2000 relations.
