 Korea traditionally had been a protectorate nation under Chinese authority.Over time after it became clear what this meant for Korea and China, Qing China attempted to recant the declaration against Japan and in August 1894 Japan began fighting with Qing (Chin) forces over the Korean Peninsula, known as the First Sino-Chinese war (1894–1895).The film "YMCA Baseball" takes places after these events have occurred and Japan has occupied Korea as a protectorate state of Japan.
