Announcing the lower-level talks held yesterday, US State Department spokeswoman Heather Nauert said: "We continue to prepare for a meeting between the president and North Korean leader Kim Jong-un".
Kim Yong Chol, a former North Korean spy chief and senior official, and his aide, Choe Kang Il, head of North Korea's Ministry of People's Security, are expected to meet Secretary of State Mike Pompeo in the US this week.
North Korea's Kim Yong Chol, vice chairman of the ruling Workers' Party's Central Committee, was scheduled to fly to the United States on Wednesday after speaking to Chinese officials in Beijing, South Korea's Yonhap news agency said, citing an unnamed source. The North Korean side is led by Kim Chang Son, who effectively serves as chief of staff to Kim Jong Un.
Last week USA president Donald Trump pulled the U.S. from the summit, telling Kim Jong-un in a long-winded and at times freakish letter North Korea as displayed "tremendous anger and open hostility".
In a twitter message, Trump confirmed that Kim is "heading now to NY".
Sung Kim, the current US ambassador to the Philippines and former chief nuclear envoy, arrived in Seoul on Sunday inquiring as to Pyongyang's level of commitment to denuclearization.
Due to sanctions against him, Kim Yong Chol is banned from visiting the United States.
The issue is central in determining whether the US-North Korea meeting succeeds, and whether Moon is an effective facilitator, said Chun Yung-woo, a former South Korean national security adviser and nuclear negotiator with the North.
"When we say 'denuclearization of the Korean Peninsula, ' this could be a two-way street", Clapper said, also on "Face the Nation".
But that did not stop North Korea's state media from continuing its criticism of allied military exercises on Tuesday, saying if Washington "sincerely hopes for the talks, it should stop the acts of threatening its dialogue partner by force".
"We're still finalising exactly what these meetings will look like", she said.

The two nations allegedly sent representatives to stay in a hotel in Amman, Jordan in next door rooms. Netanyahu said he might also meet with British Prime Minister Theresa May.
The North Koreans, after expressing initial enthusiasm about diplomacy with the U.S. earlier this month, did not show up for a preparatory meeting in Singapore, threatened to use nuclear force and referred to U.S. Vice President Mike Pence as a "political dummy". Experts say this is not enough to verify that the site is no longer usable and this is likely why North Korea only allowed journalists to watch its supposed decimation.
Keep in mind that administration surrogates often don't know what is going on, the president is not a reliable indicator of what his own administration is up to, and South Korea's optimistic spin on North Korea's intentions can depart substantially from Pyongyang's actual position.
Pyongyang also demanded the United States halt future joint military drills with South Korea if it truly wishes for talks with North Korea, the North's Rodong Sinmun said on Tuesday.
North Korea denied any involvement in the attack on the ship and on Sony Pictures.
Abe spoke with Trump over the phone for about 30 minutes on Monday evening.
White House counselor Kellyanne Conway said Tuesday morning in an appearance on Fox News Channel's "Fox & Friends" that the president had "sent over two delegations - one for logistics and one for more diplomatic purposes that are on the ground making the logistic preparations for June 12".
North Korea has rejected US demands that it unilaterally abandon its nuclear program.
The talks are focused on what would be the substance of a potential summit between Trump and Kim - the issue of North Korea's nuclear weapons program. It's the second time the US team has traveled to Singapore in recent weeks.
During his unusual visit, Kim Yong Chol had dinner for about an hour-and-a-half with Secretary of State Mike Pompeo, who traveled from Washington to see him.
Officials also told NBC News that the report stated that Kim might be willing to open a Western hamburger franchise in the capital of Pyongyang as a gesture of goodwill toward Trump.
