In October 2009, when visiting Yerevan, the World Bank’s managing director, Ngozi Okonjo-Iweala, warned that Armenia will not reach a higher level of development unless its leadership changes the "oligopolistic" structure of the national economy, bolsters the rule of law and shows "zero tolerance" towards corruption. "I think you can only go so far with this economic model," Ngozi Okonjo-Iweala told a news conference in Yerevan. "Armenia is a lower middle-income country. If it wants to become a high-income or upper middle-income country, it can not do so with this kind of economic structure. That is clear." She also called for a sweeping reform of tax and customs administration, the creation of a "strong and independent judicial system" as well as a tough fight against government corruption. The warning was echoed by the International Monetary Fund.
