Japanese and South Korean parliamentary groups plan to jointly work toward making the 2020 Tokyo Olympics and Paralympics a success, with both sides setting up special committees to that end, lawmakers with knowledge of the matter said Tuesday.

The cross-party groups hope to help create an environment for Tokyo and Seoul to mend political ties that have chilled over wartime history and trade. The South Korean side broached the idea of creating the committees for coordination, according to the lawmakers, who spoke on condition of anonymity.

The envisaged units would seek to realize a visit by a group of South Korean lawmakers to Japan on the occasion of the Summer Games, and promote exchanges between citizens of the two countries through tourism.
