Opinion Formation in the World Trade Network — •Dima Shepelyansky — Lab Physique Theorique, CNRS, Toulouse, France

An approach of opinion formation is applied to the world trade network (WTN) obtained from UN COMTRADE database for years 2010-2022. Also the Google matrix methods are used to determine trade relations between countries. The trade preference of countries to perform their trade in USD, EURO or CNY are determined. An effect of possible BRICS currency is analyzed and its dominance is established in the frame of mathematical analysis of WTM flows.
