First, admitting that compulsory signing due to a threat against an individual who represents a state is invalid in the norm of the international common law in those days, there is a position to repulse the views of invalidity on the ground that historical data related to this treaty on compulsion and a threat against the individual (Emperor Gao Zong [King of Korea]) are insufficient.
まず、当時の国際慣習法規範において国家を代表する個人に対する脅迫による強制調印は無効であると認めつつも、本協約に関しては個人（皇帝・高宗(朝鮮王)）の強制と脅迫に関する歴史的資料に乏しいことから、無効論を退ける立場がある。
