Kishida said the emergency fund is in addition to 80 billion yen ($547 million) that the government previously allocated to support fisheries and seafood processing and combat damage to the reputation of Japanese products.

“We will protect the Japnaese fisheries industry at all costs,” Kishida said, asking people to help out by serving more seafood at dinner tables and other ways.

The money will be used to find new markets for Japanese seafood to replace China and fund government purchases of seafood for temporary freezing and storage. The government will also seek to expand domestic seafood consumption.

Officials said they plan to cultivate new export destinations in Taiwan, the United States, Europe, the Middle East and some southeast Asian countries — such as Malaysia and Singapore.

Kishida talked with workers at Tokyo’s Toyosu fish market last Friday to assess the impact of China’s ban and pledged to protect Japan’s seafood industry.

Kishida heads to Indonesia on Tuesday to attend the annual summit of the Association of Southeast Asian Nations, where he may face criticism over the wastewater release from Chinese Premier Li Qian, who is also attending.

Large amounts of radioactive wastewater have accumulated at the Fukushima plant since a massive earthquake and tsunami in 2011 destroyed its cooling systems and caused three reactors to melt.

All seawater and fish samples taken since the release of the treated wastewater began have been way below set safety limits for radioactivity, Japanese officials and the plant operator say.

Mainland China is the biggest overseas market for Japanese seafood, accounting for 22.5% of the total, followed by Hong Kong with 20%, making the ban a major blow for the fisheries industry.

Seafood exports are a fraction of Japan’s total exports, and the ban’s impact on overall trade will be limited unless tensions escalate and China widens its restrictions to other trade sectors, said Takahide Kiuchi, executive economist at Nomura Research Institute.

Beijing is angry over U.S. trade controls that limit China’s access to semiconductor processor chips and other U.S. technology on security grounds. Japan has also curbed exports of chipmaking technology. Such restrictions imposed by Tokyo and possible future steps could cause an escalation of Chinese trade bans against Japan, Kiuchi said.

“Taking into consideration such risks, the Japanese government needs to carefully think about how to deal with worsening ties with China, not just over the treated water discharge but also how it should cooperate with the United States in areas of investment and trade restrictions with China,” Kiuchi said in a recent analysis.
