Japan’s announcement that it will start a controversial discharge of treated water from the crippled Fukushima No. 1 nuclear plant into the ocean on Thursday has been met with a mixed reaction across East Asia.

After reaching an agreement with the International Atomic Energy Agency (IAEA) on the sharing of information about the operation, South Korea on Tuesday announced that it would not stand in the way of Japan’s plan, saying that it doesn’t entail any scientific or technical problems, the Yonhap news agency reported.

In a statement released Tuesday, the IAEA said it would establish a communication channel with South Korea — dubbed the “IAEA-ROK Fukushima Information Mechanisms” — in order to share relevant and timely information with Seoul.
