Cooperation is, at the same time, a crucial condition of the new international economic order, expressed via the lato sensu international trade which embraces a limitless range of economic, technical, financial, banking and similar operations. The legal relations between the states acting as sovereign powers ( de jure imperii), between them and the international government organizations, as well as the organizations falling within the sphere of public international law regulation and, more precisely, of international economic law and of international development law as branches of international public law, when such legal relations refer to the field of international economic cooperation. International commercial law and international public law also feature important points of convergence, essentially stemming from the element of internationality that characterizes in equal measure the legal relations that represent their subject of regulation. Thus, the fundamental principles of international public law also apply to within the international commercial law relations and, a fortiori, to those which involve the participation of the stat. The correlation between these two legal subjects is more obvious in certain situations, such as in terms of the consequences exerted by interstate economic agreements on international trade agreements.
