OpenAI, the developer of artificial intelligence chatbot ChatGPT, released a report on Thursday saying that a group based in China had used its technology for social media posts and other activities aimed at influencing public opinion on treated water released from the crippled Fukushima No. 1 nuclear power plant.

“A few articles generated in late 2023 in English, Japanese, Chinese, Korean and Russian accused Japan of polluting Pacific waters with the discharge from the Fukushima nuclear plant — a long-running theme of Chinese IO (influence operations),” it said.

China and Japan have been at odds over the discharge of treated water from the plant into the Pacific Ocean that began last August, with Beijing imposing a ban on seafood imports from Japan following multiple releases of the water.
