The First Sino-Japanese War was the event that opened Asian nations, particularly China, to trade with Europe.

The First Sino-Japanese War (1 August 1894 - 17 April 1895) was fought between the Qing Empire and the Empire of Japan, primarily over influence of Korea. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the port of Weihaiwei, the Qing government sued for peace in February 1895.
