A special UN envoy said on Friday he was "very satisfied" after talks with Democratic People's Republic of Korea (DPRK) officials.

Lynn Pascoe, UN under-secretary-general for political affairs and special envoy of UN Secretary-General Ban Ki-moon, made the comment to Xinhua at the airport as he left the DPRK after a four-day visit.

When asked whether the nuclear issue was discussed, he answered, "we discussed many problems."

During his visit, Pascoe met with the President of the Presidium of the Supreme People's Assembly, Kim Yong Nam, and Foreign Minister Pak Ui Chun, according to the official news agency KCNA, which gave no further details of the meetings.

Pascoe is the first high-level UN official to visit the country since 2004.

The UN Security Council on June 12, 2009, adopted Resolution 1874, which allowed wider sanctions over the DPRK's May 25 nuclear test.

The resolution banned all weapons exports from the DPRK and most arms imports into the country, authorized UN member states to inspect the DPRK's sea, air and land cargo and required them to seize and destroy any goods transported in violation of the sanctions.

The DPRK has rejected the resolution and announced its withdrawal from the six-party talks aimed at denuclearizing the Korean Peninsula.
