South Korea may adopt unilateral measures against North Korea in response to Friday’s second intercontinental ballistic missile (ICBM), President Moon Jae-in said today.

Quoted by Blue House spokesperson Yoon Young-chan to a press briefing, the President said the test, which North Korea has said was of the Hwasong-14 ICBM, could represent a “fundamental change” in northeast Asia’s “security framework.”

“If necessary, [I] called for [the government] to review the plan on our unilateral sanctions against South Korea,” Moon reportedly said.

“I hope [the government] will review strong and practical measures so that the firm response won’t be just words (without action)
