South Korean lawmakers from a nonpartisan group have met with Japanese Prime Minister Kishida Fumio in Seoul.
Senior members from the South Korea-Japan parliamentarians' union spoke to reporters after the meeting on Monday.
The head of the group, Chung Jin-suk, is a lawmaker of the ruling People Power Party. He indicated that he welcomed Japan's stance toward improving bilateral ties. Chung said he had told Kishida that the prime minister's warm message regarding wartime labor was impressive.
The secretary general of the union, Yun Ho-jung, is a lawmaker of the main opposition Democratic Party. Yun said he had conveyed the concerns of South Koreans over Japan's plan to release treated and diluted water from the crippled Fukushima Daiichi nuclear power plant into the ocean.
Yun referred to the two countries' agreement that Seoul will send experts to the plant this month.
He said he had asked for efforts to make the experts' visit an opportunity for inspection and verification.
The treated water will be diluted with seawater before it is discharged. The Japanese government says the level of radioactive tritium will be lowered to one-seventh of the World Health Organization's standards for drinking water.
