ASTANA. March 11. KAZINFORM /Aigul Tulekbayeva/ The issue on introduction of a single world currency could enter the agenda of the largest world political, economic summits and forums including the G8 and G20, President Nursultan Nazarbayev considers. As is known London is to host the G20 meeting in April. “I understand that the idea of establishment of a single world currency as one of the ways of overcoming the crisis can seem too ambitious. But yesterday’s meetings with the Noble Prize laureates Robert Mandell and Edmund Phelps and other scientists showed that these proposals are quite rational and they are supported”, the President said. According to N. Nazarbayev the current crisis is a result of imperfection of the world currency which does not correspond to changes in the world; it is not democratic and the world currency market is uncompetitive and uncivilized. The next, III Astana Economic Forum is planned to be held in July 2010, the President said.
