South Korean envoys briefed American officials on Thursday on their unprecedented meeting with North Korean leader Kim Jong Un. Even so, the U.S. secretary of state said that though “talks about talks” might be possible with Pyongyang, denuclearization negotiations were likely a long way off.

South Korea’s National Security Office head Chung Eui-yong and National Intelligence Service chief Suh Hoon flew to Washington. There they were expected to explain North Korea’s stance on possible future talks with Washington and the prospect of Pyongyang suspending nuclear tests if the security of the North’s government is assured.
