Bulgaria, on its part, aspires to have as good economic relations with Japan as its political ones, Mr. Borissov said. Boosting economic relations was Bulgaria’s major goal and therefore the Bulgarian delegation held meetings with a number of businesses.

Bulgaria has shown readiness to cooperate in agriculture, greenhouse gases trading, as well as investments in industrial technologies, renewable energy sources and nuclear power.

Mr. Borissov voiced his hopes that Japanese companies would invest in the Bulgarian sea and river ports on the basis of concession.
