On this basis, the canonical equation of monetary circulation in the economy was established, which is the basis of the formulated principle of sustainable economic development. The canonical equation of money circulation is the basis for the classification of states of economic equilibrium. The developed approach is applied to the analysis of the economy of Ukraine, Germany, France and Italy. A new method of studying international trade and its influence on the countries of the world has been developed. The concept of the ideal state of equilibrium of world trade is introduced and the study of deviations from the state of ideal equilibrium is presented. A mathematical model of international trade is introduced and the problem is formulated. The concept of strict consistency of the supply structure with the demand structure is introduced and sufficient conditions are established for presenting the supply matrix through the demand matrix. In the case of strict coordination of supply and demand structures, the necessary and sufficient conditions for the existence of an integral solution of a nonlinear system of equations are given, which are essentially the conditions for the existence of an equilibrium vector of prices for which the markets are cleared. The quality of states of economic equilibrium is studied. The concept of the multiplicity of degeneration of the equilibrium state and the concept of recession of the economy are introduced. Sufficient conditions have been formulated under which a recession is possible in the world economy. International trade between the G20 countries was studied.
