With Japan's European allies heavily involved in the war in Europe, Japan sought to further consolidate its position in China by presenting the Twenty-One Demands to Chinese President Yuan Shikai in January 1915. If achieved, the Twenty-One Demands would have essentially reduced China to a Japanese protectorate, and at the expense of numerous privileges already enjoyed by the European powers in their respective spheres of influence within China. In the face of slow negotiations with the Chinese government, widespread and increasing anti-Japanese sentiments, and international condemnation (particularly from the United States), Japan withdrew the final group of demands, and a treaty was signed by China on 25 May 1915.
