U.S. tells North Korea new missile launch would be "huge mistake"

SEOUL (Reuters) - U.S. Secretary of State John Kerry warned North Korea on Friday it would be a "huge mistake" to test launch a medium-range missile and said the United States would never accept the reclusive country as a nuclear power.

Addressing reporters after talks with South Korea's president and leaders of the 28,000-strong U.S. military contingent in the country, Kerry also said it was up to China, North Korea's sole major ally, to "put some teeth" into efforts to press Pyongyang to abandon its nuclear ambitions.
