The USA position:
The USA’s position is full-for-full: full denuclearization for full sanctions relief. North Korea was willing to trade the dismantling of the main nuclear facility, with international and U.S. oversight, for full and immediate sanctions relief. That is not acceptable, since NK would retain other nuclear facilities.
N. Korea’s rebuttal:
The North Korean spokesman claims that (1) North Korea only asked for partial sanctions relief; (2) the dismantling of their main facility is the most they can offer, based on the current level of trust between the two countries.
