North Korea said Monday that the United States will pay a "due price" and experience the "greatest pain and suffering" if additional sanctions pushed by Washington are approved by the U.N. Security Council over Pyongyang's most powerful nuclear test yet about a week ago.

North Korea said in a statement that the rest of the world will witness how it "tames the U.S. gangsters by taking series of action tougher than they have ever envisaged."

The statement of the Foreign Ministry, carried by the official Korean Central News Agency, was issued as the United States and its allies are trying to have the U.N. Security Council impose the toughest possible sanctions on Pyongyang in response to its sixth nuclear test on Sept. 3.

Calling the United States as "going frantic" to spearhead the sanctions campaign, the statement said North Korea "is ready and willing to use any form of ultimate means" and "will cause the United States the greatest pain and suffering it had ever gone through in its entire history."

It is the first time since July last year that the Foreign Ministry has issued a statement.

The ministry very often conveys North Korea's positions to the outside world in the name of a spokesman, but the issuance of a statement only happens when it deems it extremely important.

The 15-member Security Council is scheduled to vote Monday afternoon in New York on a resolution toughening sanctions on North Korea.

The final draft of the resolution calls for capping the annual supply or exports to North Korea of gasoline and all other refined petroleum products to a total of 2 million barrels per year.

If backed by all five permanent members of the Security Council -- Britain, China, France, Russia and the United States -- and at least nine other countries belonging to the highest-decision making body of the United Nations, the resolution would also limit crude oil exports to North Korea to current levels, specifically, not allowing the total amount to exceed that of the previous 12 months.

The final draft, seen by Kyodo News, dropped some of the strict measures the United States had initially proposed, which included an oil embargo and a freeze on North Korean leader Kim Jong Un's assets.

The compromise draft text, however, still says that U.N. members would be required to neither import North Korea's textile products nor permit citizens of the secretive country to work in their countries.

At stake is whether China and Russia would allow much tougher sanctions against North Korea, such as caps on exports.

The North Korean ministry accused the United States of using Pyongyang's "legitimate self-defensive measures as an excuse to strangle and completely suffocate it."

North Korea has "developed and perfected the super-powerful thermo-nuclear weapon as a means to deter the ever-increasing hostile moves and nuclear threat of the U.S. and defuse the danger of nuclear war looming over the Korean peninsula and the region," the statement said.

The official media reported on Sunday that Kim has attended a special banquet for the scientists involved in what he called the "perfect success" of a hydrogen bomb test and ordered them to further help strengthen the country's nuclear deterrence.
