The United States on Monday boasted its deterrent capability over the Democratic People's Republic of Korea (DPRK) after reports that the DPRK test-fired a short-range missile.

"We have, after all, a very strong alliance with South Korea and a very strong alliance with Japan. And of course the United States maintains significant -- and I want to underline 'significant' -- deterrent capability of all kinds in the Asia-Pacific region," US Secretary of State Condoleezza Rice said aftertalks with French Foreign Minister Michel Barnier.

"I don't think there should be any doubt about our ability to deter whatever the North Koreans are up to, but that does not mean that it is not a serious problem and that the North Koreans shouldn't come back to the six-party talks," Rice said.

The test of DPRK's missiles "will at some point have to be a part of the discussions," Rice said.

"It appears that there was a test of a short-range missile by the North Koreans and it landed in the Sea of Japan. We're not surprised by this. The North Koreans have tested their missiles before, " White House Chief of Staff Andrew Card said in an interview with CNN's "Late Edition."
