In addition, the actual birthplace of Kim Jong-Il remains a mystery. According to official records in North Korea, Kim Jong Il was born on the border between China and North Korea, on the ‘Long White mountain, at the ‘White Top Mountain Secret Camp’, because this is known as the place where Kim Il Sung led guerrilla forces from. However, there are contradictions related to these facts. For instance, in the first half of 1940, almost all of Kim Il Sung’s family – that is his parents and his wife – were living in the Soviet Union. As they travelled between the South Camp (situated in Vladivostok) and North Camp (situated in Khabarovsk) during this time period, it is likely that Kim Jong-Il’s birth place was not at the ‘White Top Mountain Secret Camp’.
