The Tientsin Convention (天津条約, Tenshin Jōyaku), also known as the Tianjin Convention,[1] was an agreement signed by the Qing Empire of China and the Empire of Japan in Tientsin, China on 18 April 1885.
The coup failed when China dispatched 1500 soldiers under Yuan Shikai.
The driving out of the Japanese soldiers by Chinese troops greatly increased tension between the two powers.
Following extensive negotiations, Itō Hirobumi of Japan and Li Hongzhang of China attempted to defuse tensions by signing an agreement whereby: The Convention effectively eliminated China's claim to exclusive influence over the Joseon dynasty of Korea, and made Joseon a co-protectorate of both China and Japan.
[2] Despite negotiations, the convention was no deterrent to either party, and the next serious confrontation over Joseon quickly escalated into the First Sino-Japanese War.
