USA and North Korean officials are set to hold more talks next week but hopes for concrete steps toward North Korea's denuclearization are fading.
"But in order for it to happen, everything has to go together - resolution of the North Korean nuclear issue, the U.S".
The finding comes ahead of a second planned summit between the North Korean leader and U.S. President Donald Trump.

"Little to no verifiable change has occurred and North Korea's military capabilities", Abrams told the Senate Armed Services Committee. "Further, North Korea's conventional and asymmetric military capabilities along with their continued development of advanced conventional systems remain unchecked".
The top USA military commander in South Korea said Tuesday that North Korea has made few, if any, changes to its military posture and has provided no evidence it intends to end its nuclear program since agreeing to do so in the summer.
Gen. Abrams' comments fall in line with recent testimony by top US intelligence leaders, who testified that the North Korean regime has no plans to scale back its military capabilities or fully dismantle its growing nuclear arsenal.
North Korea has produced enough bomb fuel to build seven more nuclear weapons since talks began with the United States, a study has revealed.

The comments underscore the stalled diplomacy between the US and North Korea since President Donald Trump and Kim Jong Un agreed last June in Singapore to work toward the denuclearization of the Korean peninsula.
