Japan will keep calling on the United States to accept a 2010 agreement for the governance reforms of International Monetary Fund, a deal which will enhance voices from the emerging economies within the multilateral lender, Japanese Finance Minister Jun Azumi said Tuesday.

"We will try to convince the United States," Azumi said. But he also said that he understands it is difficult for the U.S. to make any politically sensitive decision ahead of the presidential election later this year.

Emerging economies such as Brazil, China and India have made their calls for swiftly making the reforms effective, showing reluctance to make additional commitments to the organization unless they gain louder voices within the IMF reflecting their growing importance in the global economy.

Tokyo will host the annual meetings of the IMF and the World Bank, in October.
