Washington, June 8 The Obama Administration is working with US allies to develop ways to cut off North Korean shipments that may be carrying nuclear technology or other weapons.

Asked about a request from a group of senators for the administration to consider re-designating North Korea a terrorism sponsor, Secretary of State Hillary Clinton said the administration would look into it.

Clinton said in an interview broadcast on Sunday, that failing to take aggressive and effective action against North Korea, could spark an arms race in northeast Asia.

"We will do everything we can to both interdict it and prevent it and shut off their flow of money," Clinton said of possible attempts by North Korea to ship nuclear material.

Clinton also said the US is considering returning North Korea to a list of state sponsors of terrorism, after President Barack Obama pledged "a very hard look" at tougher measures because of the North's nuclear stance.

Clinton, appearing on ABC's "This Week," called North Korea's latest actions very provocative and belligerent."

The communist regime performed a nuclear test last month and has conducted a series of short-range missile tests, FOX News reported.

The actions have triggered condemnation from the international community, but little concrete action.

Clinton said she's also looking for additional sanctions against the country in the United Nations, and potentially an arms embargo or other measures. She called for a "very strong resolution with teeth that will have consequences for the North Korean regime." (ANI)
