SEOUL-- The sister of North Korean leader Kim Jong-un on Wednesday warned that inter-Korean relations could be completely destroyed, criticizing President Moon Jae-in's attendance at a test of a submarine-launched ballistic missile (SLBM).

The statement from Kim Yo-jong came shortly after Moon said that South Korea's upgrading of its missile capabilities can help deter North Korean provocation following the successful underwater test-launch of an indigenous SLBM at a local test site.

"If even the 'president' supports the act of faulting and hurting the dialogue partner, it will naturally result in a corresponding action and then the north-south relations will end up in a total deadlock," she said.
