South Korea has shown some understanding to Japan's decision to release treated water from the crippled Fukushima Daiichi nuclear power plant into the ocean.
Seoul earlier called the decision totally unacceptable and summoned Japanese Ambassador to South Korea Aiboshi Koichi to lodge a complaint.
In parliament on Monday, South Korean Foreign Minister Chung Eui-yong listed three conditions that he is requesting Tokyo to meet.
First, he requested that Tokyo provide scientific evidence that the measure is safe; second, he urged in-depth prior consultations; and third, he called for the inclusion of South Korean experts in the verification process by the International Atomic Energy Agency.
He said if Japan follows the due processes under the standards of the IAEA, Seoul has no particular reason to object.
On Saturday, Chung expressed South Korea's serious concern over Japan's decision to the visiting US special presidential envoy for climate, John Kerry. He sought Washington's cooperation with Seoul on the issue. Kerry responded that it would not be appropriate for the United States to intervene in an ongoing process.
The Japanese government plans to treat the wastewater from the power plant to remove most radioactive materials and dilute it so the concentration of the remaining tritium is below national standards before discharging it.
