(CNN) North Korea is considering suspension of denuclearization talks with the United States, Deputy Foreign Minister Choe Son Hui told reporters on Friday.

"We have no intention to yield to the US demands [put forward at the Hanoi summit] in any form, nor are we willing to engage in negotiations of this kind," said Choe, according to Russian state news agency TASS, which attended the press event in Pyongyang.

Choe said the North was deeply disappointed by the failure of the two sides to reach any agreements at last month's summit between Kim Jong Un and US President Donald Trump in the Vietnamese capital of Hanoi.

She blamed the breakdown of talks on the US side, saying the American delegation was being too demanding and inflexible: [The US] "were too busy with pursuing their own political interests and had no sincere intention to achieve a result," Choe added, according to TASS.

However, US National Security Advisor John Bolton disputed Choe's characterization of the breakdown of talks as "inaccurate" and said he had discussed the reports from North Korea with his South Korean counterparts.
