Vice Defense Minister Baek Seung-joo and his Japanese counterpart Masanori Nishi are expected to meet on the sidelines of the 2nd Seoul Defense Dialogue slated for Nov. 11-13.
The vice defense ministers meet for the first time in two years amid icy relations between the neighbors.
The SDD is a forum where officials from the Asia-Pacific region and international organizations like UN, the EU, and the NATO, gather to discuss regional security issues.
Japanese media said Nishi will propose bilateral defense ministers talks and push for the conclusion of a military information protection treaty, which has been put on a back burner due to vociferous opposition here.
Talks were cancelled right before the treaty was supposed to be signed in June of last year.
Baek will express worries about Japan's attempts to legitimize sending troops overseas.
