South Korean Ambassador to Washington Han Sung-joo says the six-way nuclear talks would be held next month as originally scheduled.

Speaking at an academic seminar in New Jersey on Sunday, Ambassador Han said it is highly likely that the nuclear negotiations will be resumed since South Korea, the United States, China and Japan are trying to arrange the talks.

But the ambassador was uncertain as to a progress of the negotiations.

North Korea has recently threatened to boycott the six-party nuclear talks following U.S. President George W. Bush's denunciation of North Korean leader Kim Jong-il as a "tyrant."

The two Koreas, the United States, China, Russia and Japan met in Beijing in June for a third round of multilateral high-level discussions to difuse the international standoff over North Korea's nuclear weapons program.

But the talks ended inconclusively, with only an agreement to hold the fourth round of talks by the end of September.
