The fourth round of six-way negotiations to resolve North Korea's nuclear issue might be held late next month.

Russia's Interfax news agency, quoting Russian parliamentary sources, said Monday that the prospective date of the next six-way talks would be September 25th.

The six member-nations of the talks, including the two Koreas and the United States, agreed to reconvene before the end of next month during the latest round of high-level dialogue held in Beijing in June.

The six countries are currently pushing to hold a working-group meeting to prepare for the September talks.
