China retaliates as Japan discharges treated radioactive water from Fukushima · Global Voices

Japan is facing criticism and controversy after it began discharging treated water from the Fukushima-1 nuclear power plant into the Pacific Ocean. There have been protests throughout the region in response to the move, and on August 24, 2023, China imposed a complete ban on importing seafood from Japan.
After Japan announced the discharge in February, China condemned the move as “extremely irresponsible” and demanded that it seek authorization from neighbouring countries even though the intergovernmental organization International Atomic Energy Agency (IAEA)’s safety review found that the discharge plan was consistent with IAEA’s Safety Standards as the treated wastewater had a negligible radiological impact to people and the environment.
Twitter user @MrSeanHaines collected several commentaries and political cartoons about the wastewater discharge from state-owned media sources:
A lot of PRC officials, state media today upset with Fukushima nuclear plant for releasing waste water into the ocean.
One thing they forget to mention China does too. 6x more. pic.twitter.com/YcCoDFs2OS

In addition, falsified claims that the Japanese government bribed the IAEA with one million Euros had gone viral on Chinese social media, and many Chinese netizens are spreading the conspiracy that radioactive residue in the discharge water will damage human DNA and increase the risk of cancer. Some pointed to Fukushima’s cancer data (2012–2017) to fuel the fear, though the spike might be due to an increase in cancer screenings.
Fukushima’s nuclear crisis occurred in 2011 after a tsunami hit the nuclear power plant, which caused a power cut and led to three nuclear meltdowns and hydrogen explosions. The district was contaminated by radioactive material, and about 110,000 people were evacuated.
To cool down the reactors, the Tokyo Electric Power Company (TEPC) pumped 150 tons of water daily and stored the contaminated water in 1,061 water tanks. The discharged water came from these tanks. The melted-down reactors will take 30-40 years to be fully decommissioned.
Scientific data shows that the treated discharge is safe as it was processed with the Advanced Liquid Processing System (ALPS) to remove most radioactive materials. It was stored in water tanks for over a decade to allow the radioactive materials to undergo nuclear decay and then diluted with sea water with a ratio of 1:100 to reduce the level of Tritium — a radioactive material that cannot be filtered out by ALPS — before being discharged into the sea. Data also indicate that the Tritium concentration level of the Fukushima discharge water is far lower than other nuclear power plants, including those from mainland China.
Yet, most mainland Chinese media outlets and influencers are ignoring the scientific data and arguing that Fukushima’s discharge was more radioactive than other nuclear power plants as it was used to cool down meltdown reactors. Dissent has been censored on all Chinese social networks.
Articles that explained the safety standards of the IAEA, the ALPS water treatment system, and the rationale behind the discharge plan over other options from a scientific angle were taken offline, as shown in the Chinese Digital Times’ censorship collections.
On the other hand, the Chinese government’s complete ban on Japanese seafood has received popular support. Anti-Japanese sentiment is rising in China, and many online comments describe the act as a “crime” against humanity on Chinese social media.
While China’s seafood ban has hurt Japan’s fishing industry, many observers pointed out the action may also hurt its own economy. First, thousands of Japanese restaurants in mainland China will be forced to change their menus and will probably lose their customers thanks to the food ban and surging anti-Japanese sentiment.
Secondly, after months of reports from state media about the “nuclear discharge catastrophe”, many mainland Chinese firmly believe that the sea is contaminated, resulting in collateral damage to the Chinese fisheries and aquaculture sector. Manya Koetse from What's on Weibo reposted clips taken from Chinese fish markets on August 24:
This is a difficult time for those in China's fishmarket. Some sellers got visibly upset during e-commerce livestreams this week, repeatedly seeing comments saying their fish must be contaminated after Japan starting discharging treated Fukushima cool water into the Pacific. pic.twitter.com/001WuFfUbe

Hu Xijun, the top commentator from state-owned Global Times, expressed his concern by managing fear on Weibo:
在情况有些混沌的时候，我们应保护好儿童，有生育计划和可能性的年轻人也要多注意，可采取安全的高标准。无生育计划的壮年人，还有老年人，我觉得可以放开些。低剂量核辐射经过鱼类的消化，再转到人的身上，我相信产生作用的过程会非常缓慢，壮年以上的人（我是指40岁以上且不再有生育计划的人）无需过度担心。老胡本人会继续吃国家检测部门肯定的所有国产海产品，日本货从此拜拜了，但中国渔民和养殖户是无辜的，我愿意与他们共渡难关。
In the current chaos, we should protect children and young people with birth plans. They can adopt a higher food safety standard. For those who are in the prime time with no birth plans and the elderly, we can be less strict. A low concentration of radiation, after being digested by fishes and transferred to human beings, the process for the [radiation] to take effect will be very slow. Hence, those above 40s with no birth plans need not worry too much. For myself, I will continue to eat all domestic seafood and aquaculture, which are approved by the state’s quality supervision authorities. No more Japanese seafood, but the Chinese fishermen and aquaculture farmers are innocent, and I am willing to stand with them in difficult times.
The gross production value of Chinese fisheries and aquaculture in 2021 was up to CNY 1,450 billion (approximately USD 200 billion).
Some are worried that the anti-Japanese sentiment could evolve into protests or even riots against Japanese businesses based in China. Chinese current affairs blogger Cai Shenkun wrote on X (formerly known as Twitter):
中国反日浪潮高涨，目前更多还是在网上喧哗，如果任其发展，演变成网下集会或上街游行或打砸日本车日料店，进而给政府施加压力，要求对日本排放核污水实施更严厉制裁，不仅拒绝日货，还要赶走日资，民粹鼓动起来很容易，一旦失控抑或偏离方向，这把火很可能烧到自己，特别是烧到在中国市场占有率挺高的… pic.twitter.com/67qqSIPSvV

The surging anti-Japanese sentiment is primarily online expressions. Once escalated, it may result in protests or attacks on Japanese restaurants or vehicles, demanding the government to impose more sanctions against the discharge. In addition to boycotting Japanese products, they may want to kick out Japanese businesses. It is easy to incite populist sentiment, but the fire would also hurt oneself… In the past, all anti-Japanese protests were fuelled by opinion manipulation to distract domestic problems. Currently, the country also suffers from severe youth unemployment and natural disasters, so an anti-Japanese storm is timely.  [Link to the long post]
The last major anti-Japanese protests in China occurred in 2012 and turned violent as protesters in some cities vandalized Japanese cars, restaurants and shops.
Apart from China, other countries, including South Korea and Fiji, also protested against the Japanese discharge of treated water.
In response, many governments tried to ease people’s anxiety over the Fukushima discharge plan. The European Union lifted the Fukushima food import ban one month before the water discharge. The Australian government applauded Japan's transparency and international engagement in its discharge plan and affirmed the safety standard of the treated water. South Korean President Yoon Suk Yeol had a seafood lunch on August 28 to allay public concern over the safety of local fish products.
The IAEA has also set up a website providing live data from Japan on the release of treated water from Fukushima.
