Re-assertion of Chinese influence

After the Imo Incident, early reform efforts in Korea suffered a major setback. In the aftermath of the incident, the Chinese reasserted their influence over the peninsula, where they began to interfere in Korean internal affairs directly. After stationing troops at strategic points in the capital Seoul, the Chinese undertook several initiatives to gain significant influence over the Korean government. The Qing dispatched two special advisers on foreign affairs representing Chinese interests to Korea: the German Paul Georg von Möllendorff, a close confidant of Li Hongzhang, and the Chinese diplomat Ma Jianzhong. A staff of Chinese officers also took over the training of the army, providing the Koreans with 1,000 rifles, two cannons, and 10,000 rounds of ammunition. Furthermore, the Chingunyeong (Capital Guards Command), a new Korean military formation, was created and trained along Chinese lines by Yuan Shikai.

In October, the two countries signed a treaty stipulating that Korea was dependent on China and granted Chinese merchants the right to conduct overland and maritime business freely within its borders. It also gave the Chinese advantages over the Japanese and Westerners and granted them unilateral extraterritoriality privileges in civil and criminal cases. Under the treaty, the number of Chinese merchants and traders significantly increased, a severe blow to Korean merchants. Although it allowed Koreans reciprocally to trade in Beijing, the agreement was not a treaty but was in effect issued as a regulation for a vassal. Additionally, during the following year, the Chinese supervised the creation of a Korean Maritime Customs Service, headed by von Möllendorff. Korea was reduced to a semi-colonial tributary state of China with King Gojong unable to appoint diplomats without Chinese approval, and with troops stationed in the country to protect Chinese interests. China also obtained concessions in Korea, notably the Chinese concession of Incheon.
