Progress on inter-Korean relations should be in parallel with denuclearization: U.S. State Dept.

South Korea will be sending a team of presidential envoys to Pyongyang next Wednesday to discuss a range of issues, including the upcoming inter-Korean summit.
And we now have Washington's response to that.
A spokesperson at the U.S. State Department says progress on inter-Korean relations must happen in lockstep with denuclearization,... reaffirming Washington's stance that the mending of Seoul-Pyongyang ties should not be separate from denuclearization efforts.
The official said diplomatic and economic pressure on North Korea must be maintained to achieve the final, fully verified denuclearization of the regime.
