The Illustrated Treatise on the Maritime Kingdoms, or Haiguo Tuzhi, is a 19th-century Chinese gazetteer compiled by scholar-official Wei Yuan and others, based on initial translations ordered by Special Imperial Commissioner Lin Zexu. The "Treatise" is regarded as the first significant Chinese work on the West and one of China's initial responses to the Anglo-Chinese First Opium War (18391842). Eventually stretching to one hundred "juan", or scrolls, the treatise contains numerous maps and much geographical detail covering both the western and eastern hemispheres. Wei's book also garnered significant interest in Japan and helped mould the country's foreign policy with respect to the West.
