The American media report that if the meeting of the presidents of the United States and the People's Republic of China in Buenos Aires in November does not bring progress in trade relations between the two countries, the US authorities may impose duties on the entire volume of goods imported from China. Oil supplies from OPEC countries declined in October to their lowest level since April 2017 due to the fall in Iran’s exports.
