The "green economy" and nuclear energy development within the BRICS and the CIS are on agenda of the St. Petersburg International Economic Forum. For the first time, Belarus has presented its exposition at the large-scale forum that features twelve thousand businessmen and politicians from 130 countries. By the way, our republic, which has been building the nuclear power plant, is one of the leaders among the IAEA member states in terms of the number of the agency’s missions conducted and requested before the first power unit of the NPP is commissioned.
