Experts from China will be invited to be part of an International Atomic Energy Agency (IAEA) technical working group pertaining to Japan's disposal of nuclear wastewater, a Chinese Foreign Ministry spokesperson said Monday.

Spokesperson Wang Wenbin told a daily press briefing that the news was recently confirmed by the IAEA.

Noting that the Fukushima nuclear accident is one of the most serious in the world, Wang said the Japanese government, in disregard of concerns and opposition both at home and abroad, has unilaterally decided to discharge the wastewater into the sea without exhausting means for safe disposal, disclosing complete relevant information, or having sufficient consultations with neighboring countries and the international community.

"Such an irresponsible act not only directly jeopardizes the immediate interests of the people in Japan's neighboring countries, but also poses threats to the global marine environment and international public health security," the spokesperson said.
