SINGAPORE (AP) -- A former senior U.S. official says an American delegation urged the resumption of official nuclear talks during two days of informal meetings with North Korea's senior nuclear envoy.
North Korean envoy Ri Yong Ho repeated to reporters on Tuesday his country's demand that Washington and Seoul stop annual military drills that Pyongyang says are invasion preparations.
The comments came after the end of so-called Track Two talks led by Ri and former U.S. special envoy for North Korea policy Stephen Bosworth.
Bosworth said the U.S. side sees a "priority need to get official discussion back underway."
Washington and Pyongyang have no formal diplomatic ties, but former U.S. officials occasionally meet North Korean diplomats to discuss Pyongyang's nuclear ambitions.
Six-nation talks over Pyongyang's nuclear program haven't been held since late 2008.
