After the 1920 election, newly elected Republican President Warren G. Harding appointed Hoover as Secretary of Commerce; Hoover continued to serve under President Calvin Coolidge after Harding died in 1923. The Boxer Rebellion broke out shortly after Hoover arrived in China, trapping the Hoovers and numerous other foreign nationals until a multi-national military force defeated Boxer forces in the Battle of Tientsin. Fearing the imminent collapse of the Chinese government, the director of the Chinese Engineering and Mining Company agreed to establish a new Sino-British venture with Bewick, Moreing. After Hoover and Bewick, Moreing established effective control over the new Chinese mining company, Hoover became the operating partner of Bewick, Moreing in late 1901.
