World War I began at the time when China entered a new period after the end of feudalism. In April 1912, the Chinese military official
Yuan Shikai gained power and ended the rule of the
Qing dynasty. Yuan became the president of the Republic of China while he sought to reinforce the central government. China was neutral at the start of the war, as the country was financially chaotic, unstable politically, and militarily weak. Yuan attempted to hold China’s neutrality in the war, an idea that was favoured by the German ''
chargé d'affaires'' in Peking,
Adolf Georg von Maltzan. In 1914, Japanese and British military forces liquidated some of
Germany's holdings in China. Yuan secretly offered British diplomat
John Jordan 50,000 troops to retake the German military colony in
Tsingtao, but he was refused. In January 1915, Japan issued an ultimatum called the
Twenty-One Demands to the Chinese government. They included Japanese control of former German rights, 99-year leases in southern
Manchuria, an interest in steel mills, and concessions regarding railways. After China rejected Japan's initial proposal, a reduced set of "Thirteen Demands" was transmitted in May, with a two-day deadline for response. Yuan, competing with other local
warlords to become the ruler of all China, was not in a position to risk war with Japan, and accepted
appeasement. The final form of the treaty was signed by both parties on 25 May 1915. ==Events of 1916==
