PYONGYANG, Dec. 24 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) issued on Sunday a strong-worded statement condemning the latest UN resolution to impose more sanctions over its nuclear and missile programs, calling it "an act of war."

A spokesperson for the DPRK's Ministry of Foreign Affairs accused the United States of getting more "frenzied" in imposing the harshest ever sanctions.

A stern-faced broadcaster of Korean Central Television read the statement which condemned UN Security Council Resolution 2397 adopted unanimously Friday to restrict oil export to the country and demand repatriation of all DPRK citizens working abroad.

"We define this 'sanctions resolution' rigged up by the U.S. and its followers as a grave infringement upon the sovereignty of our Republic, as an act of war violating peace and stability in the Korean Peninsula and the region and categorically reject the 'resolution'," said the statement.

It reiterated the DPRK's nuclear weapons are intended for self-defensive deterrence in order "to put an end to the hostile policy and nuclear threats and blackmail of the U.S."

The new punitive measures included in the UN resolution will significantly cut short refined petroleum exports to Pyongyang, put a lid on its crude oil imports, ask UN member states to repatriate DPRK nationals earning incomes abroad, and crack down on ships illegally transferring oil to or smuggling banned items from the country.

Wu Haitao, charge d'affaires of China's permanent mission to the United Nations, said Friday's resolution reflects the unanimous position of the international community in opposing the DPRK's development of nuclear weapon and ballistic missile capabilities and in maintaining the international non-proliferation regime.
