Is there any hope for Ryukyu's return to China or independence?

First, Ryukyu is a subordinate country of China, and its relationship is aboveboard. The relationship between Japan and Ryukyu is totally kidnapping and sneaking around behind China's back. One woman will never marry another. Since Ryukyu is a vassal state of China, it can't be a Japanese vassal state. The so-called two genera is a unilateral statement by Japan. Historically, the so-called two genera mostly refer to the Qin Dynasty, but Ryukyu is not. The so-called tribute relationship between Ryukyu and Japan is actually kidnapping. Second, the Cairo Declaration made it clear that Ryukyu does not belong to Japan. As for the return of China, there are documents confirming that both the United States and the Soviet Union support it, and Britain has no interest and will not oppose it. Therefore, the real meaning of Cairo Declaration is that Ryukyu will return to China, and China also agreed to the text document, because it includes Ryukyu. No specific mention of Ryukyu does not mean that Ryukyu does not belong to China, and the four northern islands have not mentioned it. Is it different from Russia? Third, the San Francisco Peace Treaty is a treaty to implement the Cairo Declaration. It was the San Francisco Peace Treaty that separated Ryukyu from Japan, instead of handing it over to Japan. China and the Soviet Union opposed the San Francisco Peace Treaty, mainly against the unilateral rule and occupation of Ryukyu by the United States. Similarly, the San Francisco Treaty is not binding on China. The United States violated the San Francisco Treaty by handing over Ryukyu to Japan. Fourth, although many Japanese immigrated to Ryukyu, there are differences between Ryukyu and Japanese. As the territory of China, Ryukyu relies on international law, not the self-determination of local people. Conclusion: As for the future of Ryukyu, I expect Japan to take the initiative to return it, just like Britain returned to Hong Kong. Or hand over the custody of the United States to China through the United Nations, the Japanese will be fine. This also requires China to strengthen its strength and get more support from other countries.
