Cholera epidemic and quarantine of open ports in Joseon in 1886.

In 1886, cholera was prevalent nationwide in Joseon. This year was not yet the time when the Joseon government officially overhauled quarantine rules to go into effect. Thus, quarantine efforts to prevent cholera varied depending on each of the three opening ports in the Joseon Dynasty. In Wonsan, officials of the three countries(Joseon, Japan and Qing) discussed ways to deal with cholera, and quarantine activities were carried out smoothly. On the other hand, Busan underwent friction and conflict between the parties over the implementation of quarantine rules within the region. When the Japanese consulate said that it would establish quarantine rules first and implement them, officials from various countries, including the Joseon Dynasty, strongly protested against the movement, saying that they did not reach prior consent. On top of that, economic interests were also affecting circumstances of port trade. In Incheon, there were differences between the home country and the local consulate over the urgent issue to be dealt with locally and the legal principles of applying the treaty. Since consular officials were not authorized to establish quarantine rules, the situation was settled into cancellation of the rules already issued there. The Japanese consul working at each port in the Joseon Dynasty suggested specific rules to develop quarantine activities. At this point, we can read Japan's intention to preempt the standard of future quarantine inspections. The enforcement of quarantine rules, however, was a matter that required consent from the Joseon official Gamri, the Acting Commissioner of the Joseon Maritime Customs and diplomats from each country. Furthermore, they had to go through the process of obtaining review and approval from their home countries if there were any problems in the operation of the treaty. The establishment and implementation of quarantine rules were complicated by interests of various players in each country concerning protection of their own citizens. Even though it was timely and the purpose of implementation was good, it could not follow through the quarantine rules as proposed by the Japanese consul at the opening port. The accumulation of quarantine experience and information at each port of Joseon in 1886 provided the foundation for the Joseon government to move toward to establish quarantine rules and implement them with the consent of each country in the following year.
