The Japanese government is arranging to convene a summit to discuss how to share funding and cooperate toward North Korea's complete denuclearization, on the sidelines of the U.N. General Assembly gathering in late September, government sources said Tuesday.

Although Prime Minister Shinzo Abe has expressed readiness to support initial costs related to the International Atomic Energy Agency inspections, Japan is also planning to provide additional funds needed to neutralize Pyongyang's nuclear facilities and transport its nuclear materials, according to the sources.

Abe also aims to propose a new international body to manage the funds provided by each country in collaboration with the United States and South Korea, the sources added.
