China and eight Asia Pacific island countries have raised a collective objection against the disposal of wastewater from the Japan's Fukushima nuclear power plant.
China's Foreign Affairs Ministry says the nine countries adopted a joint declaration, following a meeting led by Beijing.
The declaration urges for the country which governs the issue, to make a decision regarding the disposal carefully and to cooperate with the international community.
The declaration did not directly mention Japan, but is largely seen as a protest against Tokyo's plan to release the contaminated water.
Among the eight island countries are Kiribati, Fiji, and Papua New Guinea.
