This paper discusses some specific trade disputes that produce crucial effect on the country’s economy, speculates the country’s needs and expectations for joining the World Trade Organization, combines basic international relations’theories with WTO Cardinal Principles, and makes an attempt in interpreting some case studies, in which Croatia and the other country reached a mutual agreement, from the perspective of three theories introuced in international relations : Neo-realism, Neo-liberalism, and Constructivism.
