Member states of the International Atomic Energy Agency (IAEA) passed a resolution Friday, calling on the Democratic People's Republic of Korea (DPRK) to "cooperate promptly" with the atomic agency.

The text was adopted without a vote by the General Conference of 155-nation IAEA.

The 4-day 56th IAEA General Conference that ended here on Friday "stresses its desire for a diplomatic resolution of the ( DPRK) nuclear issue so as to achieve the complete, verifiable and irreversible denuclearisation of the Korean peninsula," said the resolution.

It "reaffirms that (DPRK) cannot have the status of a nuclear- weapon state" under the nuclear Non-Proliferation Treaty (NPT), which entered into force in 1970 to prevent the spread of nuclear weapons.

The DPRK withdrawn from the NPT in 2003, and suspended cooperation with IAEA.

Early this month, the DPRK charged that the IAEA has " aggravated the nuclear issue on the Korean Peninsula," and sided with Washington's hostile policy towards Pyongyang, adding that their criticism of the DPRK's construction of a light water reactor is "in view of old standard."

In a recent report, the nuclear watchdog said the DPRK's construction of the reactor and its uranium enrichment activities have aroused serious concerns.
