2010 World cup opening ceremony took place at the Soccer City Stadium, Johannesburg on June 11th. During the ceremony, South Korean diplomat to South Africa, Han-Su Kim left his seat to use the restroom. At that moment, North Korean diplomat to South Africa, Hee-Jung Ahn snatched Kim's arm and said "If the South continue to behave that way, North Korea will not tolerate it" in an aggressive manner. North Korea is unhappy with the South Korean government's effort in raising international support over the Cheonan sinking. It is evident that the economic crisis in North Korea worsened as the international community reproached DPRK and imposed sanctions against it. However, it doesn't mean that its diplomat can openly makes threats against another nation. Even now, they are unwilling to admit their fault. What a weird nation.
