North Korea’s leader Kim Jong Un said his nuclear weapons were a “powerful deterrent” that guaranteed its sovereignty, state media reported on Sunday, hours after U.S. President Donald Trump said “only one thing will work” in dealing with the isolated country.

Trump did not make clear to what he was referring, but his comments seemed to be a further suggestion that military action was on his mind.

In a speech to a meeting of the powerful Central Committee of the ruling Workers’ Party on Saturday, a day before Trump’s most recent comments, state media said Kim had addressed the “complicated international situation”.

North Korea’s nuclear weapons are a “powerful deterrent firmly safeguarding the peace and security in the Korean peninsula and Northeast Asia,” Kim said, referring to the “protracted nuclear threats of the U.S. imperialists.”
