The U.N. nuclear watchdog adopted a resolution Friday denouncing North Korea for its continued nuclear activity.

In the resolution approved at the annual general conference of the International Atomic Energy Agency in Vienna, its member states urged North Korea "not to conduct any further nuclear test."

The secretive communist nation has conducted two underground nuclear tests, in 2006 and 2009.

The resolution also "calls upon (North Korea) to come into full compliance" with the Nuclear Non-Proliferation Treaty and abide by U.N. Security Council resolutions.

Pyongyang announced its withdrawal from the NPT in January 2003.

It also demands North Korea fulfill its commitments made under the Sept. 19, 2005, deal with its five dialogue partners in the six-party talks. In the 2005 joint statement, Pyongyang agreed to abandon its nuclear program in return for political and economic incentives.

Following a Feb. 29 agreement with the United States, Pyongyang invited an IAEA delegation to visit there to "discuss technical issues with regard to the monitoring of moratorium on uranium enrichment activities" in its main nuclear site in Yongbyon. (Yonhap News)
