The Democratic People's Republic of Korea (DPRK) "totally rejected" UN Security Council Resolution 1887 on nuclear non-proliferation and disarmament, the KCNA news agency reported Wednesday.

The DPRK "will not be bound to it at all," as the resolution was "a double-standard document," which "failed to fully reflect the desire and will of the international community," the KCNA said, citing an unnamed foreign ministry spokesman.

Countries with the most nuclear weapons should take the lead in reducing and destroying them, which was a prerequisite to establishing a "world free of nuclear weapons," said the spokesman.

The DPRK, which had lived under constant nuclear threat from the United States over the past half-century, "was compelled to have access to a nuclear deterrent," he said.

He added that the DPRK was willing to make vigorous efforts to denuclearize the Korean peninsula in the future and contribute its efforts in building a world free of nuclear weapons under the precondition that the United States changed its nuclear policy toward the DPRK.

The UN Security Council last Thursday unanimously adopted a resolution aimed at enhancing nuclear disarmament and non-proliferation.

Resolution 1887 calls for nations to begin talks on nuclear arms reduction and to negotiate "a treaty on general and complete disarmament."
