Yesterday the United Nations Security Council condemned North Korea's recent missile tests.
A day before, North Korea fired off a missile that landed in the sea near Russia. The council said that launches by North Korea reveal development in nuclear weapons delivery systems, which were increasing tensions around the world.
In a unanimously agreed statement, the 15-member council said it was of vital importance that North Korea show "sincere commitment to denuclearization through concrete action and stressed the importance of working to reduce tensions."
The statement also condemned an April 28 ballistic missile launch by Pyongyang. "To that end, the Security Council demanded the Democratic People's Republic of Korea conduct no further nuclear and ballistic missile tests," the council said, adding that it was ready to impose further sanctions on the country.
U.S. began talks with North Korean ally China on possible new UN sanctions. Traditionally, the United States and China have negotiated new measures before involving remaining council members.
The UN Security Council first imposed sanctions on North Korea in 2006 in response to its five nuclear tests and two long-range rocket launches. Pyongyang has since threatened a sixth. Experts said Sunday's successful launch signals major advances in developing an intercontinental ballistic missile, such as mastery of re-entry technology and better engine performance.
The statement also revealed that, "The members of the Security Council vowed to fully implement all measures imposed on (North Korea) by the Security Council and strongly urge all other member states to do so in an expeditious and serious manner."
North Korea made a rare global appeal in a letter released on Friday for states to reconsider enforcing UN sanctions on the Asian nation.
