The industrialized Western powers, seeking free trade, raw materials and market, turned their faces to the underdeveloped states of the Middle and the Far East in the 19^th century. First Ottoman Empire, then China and Japan became the targets of this process in a short time. Ottoman Empire was transformed into a semi colony between 1856-1881. After China’s defeat against Japan, the French and British diplomats had discussed repeating the policy which they implemented against Ottoman Empire after the Crimean War in 1853-1856, for China. Colonial effects had begun with trade agreement in Ottoman Empire and continued with changes in judiciary, land laws and increasing the rights of foreigners. Also Japan, who learned how to be a colonialist from British Empire, captured the sovereignty and made changes to judicial and social laws in Korea. In this study, we emphasized that the colonial policies were the same everywhere in both the Near East or the Far East. The Archival documents show the similarities to colonial policies implemented in the Ottoman Empire and Korea. The main source of the findings in this study is the diplomatic correspondence of British diplomats in the region, in the National Archives.
