In countries like Iran and China, some religious groups have faced many difficulties regarding their freedom of religion—particularly Christians, the subject of this research. Such restrictions include the forbiddance of worship, detention, and imprisonments among others, all of these because the choice of Christianity as a religion. Being a Christian in these countries means being private of many basic rights. For this factor, the human rights issue is also emphasized in this study. Such groups are seen as threats from the point of view of the both Chinese and Iranian governments. They represent different values than the ones exhibited by their leaders. Through the studies produced by the Copenhagen School is possible to analyze how the minorities Christians groups have became a threat to those governments. These studies, in the fields of International Security, allow us to analyze the threat as a mutable concept. Therefore the main objective is to assess when and why these groups became a threat to those governments. Through the studies of the Copenhagen School, the case of minority Christians in Iran and China are discussed as examples to prove the theoretical perspectives.
