The chief U.N. nuclear negotiator said Wednesday after talks in Pyongyang that North Korea was still committed to the denuclearization of the Korean peninsula.

The head of the UN's nuclear agency, the International Atomic Energy Agency (IAEA), is in Pyongyang for talks on the dismantling of North Korea's nuclear program.

The United States and North Korea have launched talks on normalizing relations for the first time in more than 50 years.

U.S. and North Korean finance officials have ended a second round of talks on U.S. financial sanctions against Pyongyang with no clear resolution to the dispute. Daniel Schearf reports from Beijing that North Korea has blamed the sanctions for holding up progress on parallel six-nation talks about its nuclear programs.

China's Foreign Ministry says six-country talks on North Korea's nuclear program will resume on February 8 in Beijing.

Stalled talks on North Korea's nuclear weapons programs will resume this month. They are expected to be brief, and many experts are skeptical about whether they will make any serious progress towards ending Pyongyang's nuclear programs.
