In this photo provided by the North Korean government, U.S. Secretary of State Mike Pompeo, left, shakes hands with North Korean leader Kim Jong Un as they pose for a photo in Pyongyang, North Korea, Sunday, Oct. 7, 2018.
What did Pompeo and Kim agree to?
Pompeo said he was also hopeful that Kim would allow inspectors to visit a "missile engine test site", believed to be a facility in the town of Tongchang-ri that North Korea says it has begun dismantling.
After a previous visit to Pyongyang in July, Pompeo had said the two foes made progress on key issues - but within hours of his departure the North condemned "gangster-like" demands from the U.S., raising questions over how much the two sides really saw eye to eye.
South Korean President Moon Jae-in will deliver Kim's invitation when he meets Francis next week during his trip to Europe, Blue House spokesman Kim Eui-kyeom told a news briefing. He lamented Beijing's recent decision not to attend the strategic dialogue between the two countries' defense secretaries planned for the middle of this month, saying that the forum was an "important opportunity" for discussion. Pompeo did not meet Kim on that trip.
According to the former official, the North Korean diplomats told him that denuclearization for them refers to a process by which the USA also reduces its nuclear weapons, possibly worldwide.More news: Google poised to unveil new Pixel phones, other services
Pyongyang was previously home to a vibrant Christian community, earning it the nickname "Jerusalem of the east" before the founding of North Korea.
KCNA said "there was an agreement on the issue of holding the working negotiation for the second DPRK-U.S. summit talks as early as possible, and relevant procedure-related issues and ways were also discussed".
The top U.S. diplomat also said both sides were "pretty close" to agreement on the details of a second summit, which Kim proposed to U.S. President Donald Trump in a letter last month. The US has said that it will not make such concessions unless the North takes substantive steps to do away with nuclear weapons.
Meeting at the Diaoyutai Guest House, Wang told Pompeo that the United States has "stepped up rhetoric over trade tensions" after a raft of tit-for-tat tariffs on billion of dollars in USA and Chinese goods.
Moon said a second Mr. Trump-Kim summit could be accompanied by major diplomatic developments that could contribute to the denuclearization of the Korean Peninsula and stabilizing peace.
The challenge for the USA remains stark: American administrations for decades have been stymied by North Korean intransigence on its nuclear program, and the rapport between Trump and Kim hasn't resolved that issue.
"I know that you would like to discuss the North Korea issue and other relational issues with me on this visit", Wang said.
Yang said China and the USA must expand political cooperation to achieve mutual aims.
