The UN Security Council approved new resolution against North Korea on Thursday, as the state threatened the US with a preemptive nuclear strike.
The resolution called for further economic restrictions on North-Korea including shipping and the receiving of prohibited cargo. See here for resolution.
The Chinese ambassador to the UN, Li Baodong, said Beijing wanted "full implementation" of the UN Security Council resolution.
Meanwhile a spokesperson for North Korea's foreign ministry speaking on the state's official news agency, KCNA, said:
"Since the United States is about to ignite a nuclear war, we will be exercising our right to preemptive nuclear attack against the headquarters of the aggressor in order to protect our supreme interest."
