A Pyongyang foreign ministry spokesman told a reporter for state-controlled news agency KCNA the bilateral agreement on extended nuclear deterrence is escalating tensions on the peninsula.
"The United States and the South Korean puppets last October announced an 'extended deterrence consultative group' and held their first meeting," the spokesman said, referring to the first session of the high-level Extended Deterrence Strategy and Consultation Group held last week. "This is a serious act of provocation that further aggravates the situation on the Korean peninsula and increases the risk of nuclear war."
The spokesman also said the decision to regularly deploy U.S. strategic assets to the peninsula was to "regularize, institutionalize" military pressure against North Korea.
"The United States, through the formation of a trilateral alliance with Japan and South Korea, are trying to create an Asian NATO to check their competitors, and realize their hegemonic ambition by securing military superiority in the Asia-Pacific region," the spokesman said.
The official added Pyongyang would continue to grow its nuclear arsenal to deter against the "threats."
