Boxer Protocol

The Treaty of 1901, known as the Xinchou Treaty in China, and more commonly known as Boxer Protocol or Peace Agreement between the Great Powers and China, was a peace treaty signed on September 7, 1901 between the Qing Empire of China and the Eight-Nation Alliance: the United Kingdom, the USA, Japan, Russia, France, Germany, Italy, Austro-Hungary, Belgium, Spain and the Netherlands after China's defeat in the Boxer Rebellion by the Eight Power Expeditionary Force. China later regarded this as one of a series of "Unequal Treaties" which it signed since the First Opium War. (from Wikipedia)
