Top US Negotiator on North Korea Blames Pyongyang for Deadlock Agence France-Presse SEOUL - The outgoing U.S. point man on North Korea admitted Thursday that the Trump administration had not achieved what it sought with Kim Jong Un, but blamed Pyongyang for squandering the opportunity for progress. Talks over the North's nuclear arsenal have been stalled since early last year when a summit in Hanoi between President Donald Trump and leader Kim collapsed over what the North would be willing to give up in exchange for a loosening of sanctions. Trump's extraordinary and headline-grabbing engagement with Kim had been "ambitious and bold," said U.S. Deputy Secretary of State Stephen Biegun, who has led denuclearization talks with Pyongyang, but had "yet to deliver the success we hoped for." "You might wonder if I am disappointed that we did not accomplish more over the past two years. I am," he added on his official last visit to Seoul. But he blamed Pyongyang for the failure, saying that "much opportunity has been squandered by our North Korean counterparts over the past two years," he told the Asan Institute for Policy Studies, a South Korean think tank. They "too often have devoted themselves to the search for obstacles to negotiations instead of seizing opportunities for engagement," he added. .
