A North Korean media outlet urged the United States on Thursday to accept Pyongyang's offer to dismantle its Yongbyon nuclear facilities in exchange for partial sanctions relief, insisting it is the best-possible proposal at this point.

The North put forward the proposal at last month's second summit between North Korean leader Kim Jong-un and U.S. President Donald Trump, but the U.S. turned it down, saying Pyongyang demanded the lifting of all key sanctions while offering to denuclearize Yongbyon only.

The differences led to the Feb. 27-28 summit ending without an agreement.

"Our (proposed) denuclearization steps and demand for corresponding sanctions relief sufficiently reflected the U.S. government's stance and demand as well. There can be no better way than that," Uriminzokkiri, a North Korean propaganda website, said in an article.
