US Secretary of State Mike Pompeo said Friday he hoped for a second summit between US President Donald Trump and Democratic People's Republic of Korea (DPRK) top leader Kim Jong Un "before too long."

"I'm hopeful that I get a chance to travel again to Pyongyang to continue these negotiations before too long," Pompeo told the cable network MSNBC. "And then before too long... I hope the two leaders get together again to continue to make progress on this incredible important issue for the entire world."  

"Ultimately, that'll be a decision for the president," Pompeo said, referring to the second summit between Trump and Kim.

Noting that the United States has the "patience and determination" to achieve its goal on the denuclearization of the Korean Peninsula, he added that the sanctions against the DPRK would remain until the Asian nation denuclearizes.

"Those economic sanctions will remain in place until we get to the end, till we get to that final denuclearization," Pompeo said.

In a separate interview with Fox News, Pompeo said that regarding the Trump-Kim meeting, there is still "a little bit of work" to do "to make sure conditions are right and that the two leaders are put in a position where we can make substantial progress," Pompeo said.

The White House said on Sept. 10 that it has received a letter from Kim Jong Un, requesting another meeting with Trump, noting that it was "open to" the meeting and is already "in the process of coordinating that."
