The work introduces the reader to the Far Eastern policy of the United States in 1898-1905. Written on the basis of the widespread use of unpublished archival materials, including diplomatic documentation, it reveals many, as yet unexplored pages of the history of the imperialist expansion of the United States in Manchuria. Particular attention is paid to the role of American imperialism in the preparation and conduct of the Russo-Japanese War, as well as to exposing the falsifications of American bourgeois historians. The book is designed for teachers and students of historical faculties, history teachers and propagandists, as well as readers interested in international relations in the Far East.
