The US, South Korea, and Japan will negotiate agreements on nuclear restraint with North Korea, according to Yonhap.
Deputy Secretary of State Kurt Campbell highlighted efforts to build trust in US commitments to extended deterrence through bilateral platforms with allies ahead of common challenges, including evolving threats from North Korea.
Extended deterrence refers to America's commitment to use its full range of military capabilities, including nuclear weapons, to defend its non-nuclear allies.
"I think we've taken substantial steps (for Korea). These are designed to make clear that our extended deterrence is solid, and we are determined to take the necessary steps to buttress this message of partnership and the nuclear umbrella extended deterrence applies clearly now as in the past," the deputy said.
By the American nuclear umbrella, Campbell meant a scenario where if one country becomes nuclear, it encourages others to follow suit.
"I think it is a critical component of America's foreign policy and national security to take the necessary steps to reassure leaders that our commitment remains firm," Campbell said.
Nuclear blackmail by North Korea
Earlier, we wrote that North Korea conducted nuclear counterattack drills. North Korean dictator Kim Jong Un observed and directed the exercises.
It has also been reported recently that North Korea conducted a test of a missile capable of carrying a nuclear warhead.
