North Korea is ready to resume six-party talks on its nuclear program but must maintain its readiness in the face of joint U.S.-South Korean military exercises, a senior envoy in Geneva said on Thursday.

So Se Pyong, the Democratic People's Republic of Korea's (DPRK) ambassador to the United Nations in Geneva, told Reuters that his country was not planning a nuclear or missile test.

In a wide-ranging interview, he said that reports about the ill health of its leader, Kim Jong Un, were "fabricated rumors" and that it was not clear whether the United States was willing to negotiate the release of three detained Americans.
