A senior United Nations official says North Korea has given him a very positive message on resuming six-party talks on its nuclear ambitions.

South Korea's unification ministry says U.N. General Assembly President Jean Ping made the comments during talks in Seoul with Unification Minister Chung Dong-young.  The ministry also said that Mr. Ping is to deliver a message to Washington that North Korea wants "co-existence" with the United States.

Mr. Ping arrived in Seoul Tuesday after talks in Pyongyang with North Korea's second-highest official, Kim Yong Nam.

The two Koreas, the United States, China, Russia and Japan have held three rounds of talks in Beijing on Pyongyang's nuclear ambitions.  North Korea refused to attend a fourth round planned for September, accusing the United States of a hostile policy against it.
