North Korea and the United States have agreed to resume suspended four-way talks to replace the tattered Korean War armistice with a permanent peace accord, South Korea's Yonhap news agency said Sunday. The two countries agreed on a path towards resuming the peace talks when US special envoy Stephen Bosworth visited North last week, Yonhap quoted South Korean government officials as saying. “I believe the two sides agreed on resuming the four-party peace talks once an official agreement has been made on reviving the denuclearization talks,” a South Korean government official told Yonhap, asking not to be named due to the sensitivity of the issue. “It was North Korea that first requested the matter be discussed within the four-party framework,” Yonhap quoted the official as saying.
