Foreign Minister Yun Byung-se arrived in Mongolia Monday to discuss ways of promoting a strategic partnership between Seoul and Ulan Bator, the foreign ministry said.
Yun will also discuss the security situation in Northeast Asia, a ministry official said.
During his three-day visit, he will hold a meeting with his Mongolian counterpart, Luvsanvandan Bold, according to the ministry.
"They are planning to focus on how to boost their strategic partnership and exchange views about issues in Northeast Asia including the nuclear threat from North Korea," it added.
Yun is expected to solicit cooperation from Mongolia for Seoul's main pillars of foreign policy ― "the Northeast Asia Peace and Cooperation Initiative" and "the Eurasia Initiative" ― and discuss ways to strengthen bilateral trade, the ministry said.
Next year marks the 25th anniversary of the establishment of bilateral diplomatic relations between the two countries.
