Trading processes is a vital part of human life and
any unstable situation results in the change of living conditions of
individuals. We study the power of each country in terms of
produce trade. Trade relations between countries are
represented as a network, where vertices are territories and
edges are export flows. As flows of products between participants
are heterogeneous we consider various groups of substitute goods
(cereals, fish, vegetables). We detect key participants affecting
food retail with the use of classical centrality measures. We also
perform clustering procedure in order to find communities in
networks.
