PYONGYANG, Sept. 11 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) Monday warned that the United States would face a "series of action tougher than it has ever envisaged" if Washington pushes through a new UN resolution imposing extra sanctions on Pyongyang.

"The sanctions and pressure racket of the United States to completely obliterate the DPRK's sovereignty and right to existence is reaching an extremely reckless phase," said the DPRK's Ministry of Foreign Affairs in a statement.

"The United States is going frantic to fabricate the harshest ever 'sanctions resolution' by manipulating the United Nations Security Council over the DPRK's ICBM mountable H-bomb test," it said.

"The DPRK is ready and willing to use any form of ultimate means" to respond to the new sanctions, the statement warned.

It accused the United States of "trying to use the DPRK's legitimate self-defensive measures as an excuse to strangle and completely suffocate it," saying that the latest missile and nuclear tests by the DPRK are aimed at deterring U.S. threats to peace and stability on the Korean Peninsula.

"Since the United States is revealing its nature as a blood-thirsty beast obsessed with the wild dream of reversing the DPRK's development of the state nuclear force which has already reached the completion phase, there is no way that the DPRK is going to wait and let the U.S. feast on it," it said.

"In case the U.S. eventually does rig up the illegal and unlawful 'resolution' on harsher sanctions, the DPRK shall make absolutely sure that the United Stats pays due price," it added.

The United States and Japan are pushing for a new sanctions resolution against the DPRK at the UN Security Council, after Pyongyang tested a hydrogen bomb one week ago.

The United Nations passed a resolution last month imposing additional sanctions on the DPRK and banning its export of coal, iron, iron core and sea food, after its tested two ICBM missiles in July.
