Kim Yo Jong, the sister of North Korean leader Kim Jong Un, slammed South Korea's president as "a parrot raised by America" for calling the North's recent missile test "concerning", state media KCNA reported yesterday. North Korea launched two ballistic missiles into the sea near Japan last week, underscoring steady progress in its weapons programme and ramping up pressure on the United States. Following the launches, South Korean President Jae-in Moon said the South, the North and the United States should make efforts to continue dialogue. Kim Yo Jong called Moon's remarks disgraceful for agreeing with the United States. "Such illogical and brazen-faced behaviour of South Korea is exactly the same as the gangster-like logic of the US," Kim Yo Jong said in a statement carried by KCNA.
