South Korea and Mongolia held working-level defense talks in Ulaanbaatar Monday to discuss regional security issues, including North Korea's nuclear weapons program, the Defense Ministry said.
  

The ministry said that Yoon Soon-ku, the ministry's director general on international policy, met with his Mongolian counterpart, Zagdsuren Boldbaatar, in Mongolia's capital to discuss a follow-up to a meeting between their defense chiefs held in May last year and how to enhance defense cooperation.
  

Yoon also plans to fly to Uzbekistan to hold similar working-level talks with his counterpart Wednesday, it added.
  

"This series of defense talks will serve as an occasion to deepen cooperation with Mongolia and Uzbekistan," a ministry official said. (Yonhap)
