North Korea is considering suspending nuclear talks with the United States, North Korea's deputy foreign minister Choi Sun-ho said Friday.
"He spoke at a press conference in the North Korean capital Pyongyang," the agency said.
President Kim Jong-un is due to announce his position on talks with the United States.
The second and final summit between US President Donald Trump and North Korean leader Kim ended early in the Vietnamese capital, Hanoi, without reaching an agreement between the two sides, contrary to the expectations of most observers.
US Secretary of State Mike Pompeo told a news conference after the summit that the reason for the failure was that North Korea had asked for full lifting of sanctions at the Hanoi summit, but lacked complete clarity on what it could offer in connection with the dismantling of the Yongbyon nuclear facility.
