China on Friday called for caution and restraint as the Democratic People's Republic of Korea (DPRK) top leader Kim Jong-un said its military should be ready to use nuclear weapons at any time.

Kim's remarks came just two days after the UN Security Council adopted a resolution to curb the DPRK's nuclear and missile program following its nuclear test and satellite launch.

"As the current situation on the Korean Peninsula is complicated and sensitive, China hopes relevant sides can exercise restraint and take caution in words and deeds to avoid further tension," Foreign Ministry spokesperson Hong Lei said at a regular news briefing.

The UN Security Council reiterated its demands that the DPRK abandon all nuclear weapons and other nuclear programs as well as weapons of mass destruction and ballistic missile programs.

Wednesday's resolution includes a ban on all exports from the DPRK of coal, iron, iron ore, gold, titanium ore, vanadium ore and rare earth metals. It also banned the supply of all types of aviation fuel, including rocket fuel, to the DPRK. Endi
