Taking up the topic of Poland's trade relations with foreign countries, the article draws attention to their importance in the context of contemporary security processes. Adequate trade, taking into account the economy and entrepreneurship for the country's defense, may have a positive effect on the economic stability of the state and its arms market. Both are regulated and embedded in the realities of international and legal treaties, of Poland, the European Union, and individual institutions and states. The author provides a cross-sectional description of these relations, referring to legal documents and analyzing economic relations affecting the state defense system.
