Feng was eventually eliminated from political life in 1918, when Xu Shichang, the Beiyang elder statesman, became president. His deputy Cao Kun replaced him as leader of the Zhili clique. At the end of World War I, Duan dominated Chinese representation at the Treaty of Versailles and used the Shanghai peace conference in 1919 to bring pressure on the non-Beiyang militarists supporting Sun Yat-sen's government in Guangzhou. He continued to receive Japanese funding for his army (renamed "National Defence Army"), for which he was willing to grant Japan legal succession to the German rights in Shandong (see May Fourth Movement).
