On this day, 110 years ago, April 26, 1915 (March 13, 1915 in the lunar calendar), Japan proposed an amendment to the "Twenty-one Rule" to the China government. On April 26, 1915, Japan proposed an amendment to the "21 Article" to the China government. In January, when Japan proposed the "Twenty-one Article", it only notified the four countries of Britain, the United States, Russia and France from the 1st to the 4th. After the truth of the full text of the "21 Article" was revealed, Europe and the United States fiercely criticized Japan for damaging their rights and interests in China. On February 10, British Ambassador to Japan Green went to the Japanese Ministry of Foreign Affairs to state that the British government deeply regretted that Japan had "omitted" No. 5 of its request clause. Claiming that China and Britain have reached a treaty on the Yangtze River Basin Railway,"Do not invade each other." Due to pressure from all parties, Japan proposed an amendment on April 26, with a total of 24 articles. Only some articles were replaced by an exchange of letters, which remained the same in essence. It claimed that this was "the final amendment and requested approval," and said: If China government recognizes all 24 articles, the Japanese government plans to return Jiaozhou Bay to China at an appropriate time and with additional conditions. The Yuan government believes that Japan's amendment "contains partial concessions compared with the original proposal," but there are still some provisions that "conflict with China's sovereignty, the treaty rights of other powers, and the doctrine of equal opportunity." Therefore, it cannot be accepted.
