North Korea has “no intention” to meet U.S. demands for further concessions on the nuclear program, the country’s deputy foreign minister Choe Son Hui told a press conference in Pyongyang on Friday morning.

“We have no intention to make concessions to the U.S. requirements [put forward at the Hanoi summit] in any form, much less the desire to conduct such negotiations," Choe said in a meeting with foreign ambassadors and press, according to comments carried by Russia’s TASS News Agency, warning that the U.S. risked throwing away "a golden opportunity this time."
