Japan's Ambassador has urged the United Nations to lead global efforts in ending world conflicts in order to establish peace and promote economic development.

Japanese Ambassador Kenzo Oshima was speaking at the annual high-level debate at UN Headquarters in New York where he said the UN should become more efficient and accountable for enforcing these changes.

"The UN has heavy responsibilities in today's and tomorrow's world as an indispensable global instrument for resolving conflicts, building peace, addressing emerging global threats and saying the foundation for prosperity,' Oshima said in a statement.

Oshima added that the current set-up of the Security Council leaves the 15-member body in danger of "waning credibility,'. Japan, he said, would take the initiative in pursuing a new "creative and persuasive' proposal for expanding Council membership during the current session of the General Assembly.
