White House officials said they expect North Korea to act "irresponsibly" to the sanctions, imposed Friday by the U.N. Security Council in response to the communist nation's recent nuclear tests. The sanctions include expanding an arms embargo and authorizing searches of ships thought to be carrying banned items to North Korea, such as materials that could be used in nuclear weapons development.
But the Obama administration has decided it will not react to whatever new action Pyongyang takes, such as another nuclear test, officials said. North Korea has said it would view new sanctions as a declaration of war. One reason the White House is signaling now it won't seek any new action is that it received approval for a tough sanctions regime from the Security Council
- though lacking the ability to use force to interdict and inspect ships - and is not likely to get anything tougher anytime soon.
"We're not going to jump to their drummer," Susan Rice, U.S. ambassador to the United Nations, told reporters at the White House. "We're going to implement this sanctions regime to the fullest possible extent."
If a ship refuses to be either boarded in international waters for inspection or diverted to a port, Rice said, U.S. officials "will take all necessary action" to publicize its ownership, what it is thought to be carrying and other information. The goal, she said, it "to shine a spotlight on it" and make it more difficult for countries to help the ship complete its journey, such as by refueling.
Rice also said the United States will "ramp up and intensify" its efforts to find out about suspect ships. She would not discuss any new deployment of U.S. military resources to do so, however.
"I'm not going to get into the disposition of our military assets," she said. "Suffice it to say that we'll take what steps are necessary, and we have the ability to do so."
A senior defense official said late Friday that the military, knowing the sanctions were being discussed, has been exploring ways to carry out such operations. He spoke on condition of anonymity because he was not authorized to speak on the record about issues still under discussion and not approved.
Asked if additional U.S. ships would have to be deployed for the new mission, two defense officials said only that the U.S. already has significant presence in the region.
