The agency said the idea was endorsed during Monday's six-nation talks on North Korea's nuclear program in Beijing, involving the two Koreas, China, Russia, the U.S., and Japan.
The aim of the conference is to form a regional body similar to the Organization for Security and Cooperation in Europe (OSCE) or the Association of Southeast Asian Nations (ASEAN).
This week's negotiations on North Korea, the first session in five months, are focused on reaching a deal to inspect Pyongyang's nuclear sites.
One of the main sticking points at the Beijing talks is whether North Korea will give international inspectors access to take samples from nuclear sites.
Under a six-party deal reached in February 2007, the North pledged to dismantle its plutonium-producing Yongbyon reactor and provide full information on its nuclear program. In October this year, the UN nuclear watchdog, the International Atomic Energy Agency, said the North had resumed work to deconstruct the reactor, after a break of several months.
