South Korea's Cabinet approved the pact Tuesday and Japan is expected to finalize the document soon, the Yonhap News Agency reported.
"As soon as Japan's Cabinet endorses the General Security of Military Information Agreement, possibly this week, we will formally sign the agreement with Japan," an anonymous senior official in South Korea's foreign ministry said.
The two nations have been discussing military pacts since early 2011. South Korean Defense Minister Kim Kwan-Jin planned to visit Japan in May to sign the pact but backed out because of the troubled history between the two nations, the report said. Japan ruled over the Korean Peninsula from 1910-1945.
