Earlier in the day, Russian Deputy Foreign Minister Igor Morgulov held consultations on the issue with South Korean Special Representative for Korean Peninsula Peace and Security Affairs Hwang Joon-kook.
"An exchange of views on the prospects of settling the nuclear problem of the Korean Peninsula in light of the hydrogen bomb test announced by the North Korean authorities was held. Serious concern over Pyongyang's actions that are in direct violation of the relevant UN Security Council resolutions was expressed," the ministerial statement reads.
The UN is considering a new resolution to impose tighter sanctions on North Korea. South Korea’s President Park Geun-hye asked officials to step up cooperation with the United States and regional powers to come up with response measures to Pyongyang's actions.
