North Korean leader Kim Jong’s sister will visit South Korea this week for the Pyongchang Winter Olympics. According to an information given today, he will be the first member of the ruling family to do so.

The Ministry of Integration said that Kim Yong Jong, senior member of the ruling Workers Party, will be part of a high-level delegation to Pyongchang this Friday and the leadership of this delegation will be the symbolic head of North Korea.

Both the Korean countries are divided by the uneconomic area since the end of the Korean War in 1953. The tension had increased after North Korea tested several nuclear tests last year, but due to the Olympics, it was seen growing.

Yang Moo Jin, professor of the University of North Korean Studies in Seoul, said it is very important that a family member of Kim Jong is coming to South Korea for the first time in history. He told that Kim Jong could meet South Korea’s President Moon Je-in giving him his brother’s personal letter in which he has expressed the hope of a successful host of the Olympics and has expressed his desire to improve inter-Korean relations.
