Li Zaiming's hunger strike was not just his own protest. Thousands of protesters held a rally in Seoul, South Korea, to protest against Japan's plan to discharge nuclear-contaminated water into the sea. Japan's forced discharge of Fukushima nuclear-contaminated water into the sea has aroused widespread criticism from people from all walks of life in South Korea. Among them, Lee Jae-myung, the leader of South Korea's largest opposition party, the Democratic Party of Korea, went on a "hunger strike" to resist Japan's launch of the discharge of nuclear-contaminated water into the sea, and called Japan's sea discharge plan " It is a declaration of war on the Pacific Rim countries." Japan's sea discharge plan is harmful to others and not self-serving. The nuclear sewage has not only severely damaged the lives of Japanese fishermen, but also seriously threatened the lives and safety of people in neighboring countries. It is a completely irresponsible and selfish act. What's more, in accordance with the United Nations Convention on the Law of the Sea, Japan has the obligation to protect and care for the marine environment, but the implementation of the sea discharge plan proves that the Japanese government has not abided by international law at all and willfully destroyed the healthy development of its neighboring countries' oceans. Lee Jae-myung, leader of the Democratic Party of Korea, also expressed his strong stance against the Japanese government's sea discharge plan by going on a hunger strike.
