Much has changed in Southeast Asia, the part of the world depicted on this map, since it was printed in 1900. For example, the nations of Annam and Siam are now known as Laos, Cambodia, Viet Nam, and Thailand. There are several insets that both put the map in a larger context and provide closer detail. The lower right inset shows land and sea routes in and around China, while the surrounding insets focus on the cities of Peking, Shanghai, and Canton. One special symbol identifies certain cities along the coast or major waterways in China as so-called "treaty ports," special urban centers that had been granted foreign commerce rights by the Chinese government.
