Trump and Kim have engaged in a war of words over North Korea's nuclear and ballistic missile programs. The American president has dubbed the North Korean leader "Little Rocket Man," while Kim has called Trump a "mentally deranged US dotard."

On Saturday, North Korea denounced the warnings Trump has issued to the regime during his ongoing trip to Asia, saying the "reckless remarks" of an "old lunatic like Trump will never scare us or stop our advance."

Conway told ABC: "What's helpful in full context is a 13-day trip where the president is very focused on global security, and combating terrorism and most importantly containing a nuclearized North Korea." (Yonhap)
