The top diplomats of South Korea, Japan and the United States pledged Friday to make efforts to end North Korea's destabilizing activities and bring the country back to negotiations.

Secretary of State Antony Blinken, South Korean Foreign Minister Park Jin and Japanese Foreign Minister Yoshimasa Hayashi also expressed deep regret over the failed attempt to pass a new U.N. Security Council resolution on North Korea.

The U.N. Security Council voted on the U.S.-proposed resolution but failed to pass it due to opposition from China and Russia, both veto-wielding permanent members of the council and close allies of Pyongyang.

"In spite of 13 Security Council members' support, we deeply regret that the UNSC failed to adopt a resolution in response to the DPRK's blatant and repeated violations of UNSC resolutions," the foreign ministers said in a joint statement released by the State Department.
