South Korean and Japanese lawmakers will visit Washington on Saturday at the invitation of the U.S. Department of State.

Some five South Korean lawmakers, including Deputy Speaker Chung Jin-suk, and three to five legislators from Japan are expected to make the visit.

Chung said on Tuesday that the lawmakers are set to visit the White House and other key U.S. government agencies. He said the legislators from South Korea, the U.S. and Japan are set to hold discussions on ways to restore traditional cooperative ties among their countries.

South Korean and Japanese lawmakers are also likely to share views on ways to address past issues, including Japan’s wartime sex slavery and forced labor, in order to improve bilateral ties.

Attention is being drawn to the upcoming visit as the Department of State’s invitation coincides with intent by Seoul, Washington and Tokyo to boost cooperation on North Korea issues.
