Japan may submit a new resolution for Security Council expansion to the United Nations General Assembly in September in the hope of having it adopted by the end of the year, according to government sources.

The move comes amid dim adoption prospects for a previous resolution submitted jointly by Japan, Brazil, Germany and India, the so-called Group of Four.

Japan is expected to consult with the other three members in compiling the new draft and submit it around Sept. 14, when the U.N. special summit is scheduled to start in New York, the sources said.
