US Secretary of State Mike Pompeo is "confident" that the United States will continue its "progress" with North Korea on denuclearization, CNN reported.

Speaking in Paraguay, Pompeo, however, did not speak about whether negotiations are underway for a new meeting between President Donald Trump and North Korean President Kim Jong Un. According to him, Washington and Pyongyang continued communication after the Trump and Kim's February summit in Hanoi.

"With respect to our negotiations with North Korea, I don't have anything to add other than even after Hanoi we've continued to have conversations," Pompeo said during a news conference in Paraguay. "I am confident what we did in Hanoi put us in a better place to continue to move forward."

Pompeo also stressed that Kim had "made a commitment" that he wanted his country to denuclearize.

Earlier it was reported that North Korean leader Kim Jong Un said he was ready to wait for US President Donald Trump to change his attitude to denuclearization talks until the end of the year.

“Until the end of the year, I will be patient, I will wait for the US president, although it will be difficult to come up with an opportunity as good as it was last time [during the February 27-28 summit in Vietnam’s Hanoi],” he said, adding that holding the third summit would require “constructive decisions for the improvement of relations.”

He also said that despite the failure of their latest talks in Hanoi, his personal relations with Donald Trump remained good.
