Japan and South Korea are considering holding a summit in mid-November, a Japanese government source said Friday, as the two countries try to improve relations strained by wartime issues.

Prime Minister Fumio Kishida and South Korean President Yoon Suk-yeol may meet on the sidelines of an international gathering, such as the Group of 20 summit to be held in Indonesia later this month, according to the source.

The move to bring the leaders together follows Kishida's attempt to facilitate a summit by sending former Prime Minister Taro Aso to meet Yoon in Seoul on Wednesday. The two agreed, during their 85-minute talk, on the need for further communication to improve bilateral ties.
