Secretary of State Hillary Clinton made her strongest comments yet about North Korea Tuesday during her tour of Asia.

South Korea's president said on Monday he has no intention of backing down to North Korea, which may be preparing to test-fire its longest-range missile and in recent weeks has threatened to reduce its neighbor to ashes.

The United States is imposing sanctions on several Chinese, Iranian and North Korean companies for violating arms export regulations governing missile technology and other proliferation activities.
