 However, when on July 16, 8,000 Chinese troops landed near the entrance of the Taedong River to reinforce Chinese troops garrisoned in Pyongyang, the Japanese delivered Li Hongzhang an ultimatum, threatening to take action if any further troops were sent to Korea.Consequently, General Oshima in Seoul and commanders of the Japanese warships in Korean waters received orders allowing them to initiate military operations in the event that any more Chinese troops were sent to Korea.Despite this ultimatum, Li probably suspected that the Japanese were bluffing, and were trying to measure Chinese readiness to make concessions.
