South Korea has informed Japan of its decision to fully restore a military intelligence-sharing deal with Tokyo, the foreign ministry said, as part of efforts to thaw long-frozen bilateral ties, Report informs referring to Yonhap.

South Korea sent an official letter to Japan earlier in the day via diplomatic channels informing of its decision to rescind its suspension of the General Security of Military Information Agreement (GSOMIA), the ministry said.

Signed in 2016, GSOMIA was seen as a rare symbol of security cooperation between Seoul and Tokyo before the former administration of President Moon Jae-in decided to terminate it in 2019 in protest of Tokyo’s export restrictions against Seoul.

The decision was later put on hold, but the amount of information sharing between the neighboring countries is thought to have been limited, as their relations remained strained over disputes stemming from Japan’s 1910-45 colonial rule of the Korean Peninsula.
