Kang replied "Yes" on Wednesday when a lawmaker asked her whether a Japanese media report was correct that Pompeo had complained strongly about the agreement, which was announced during a summit between the Koreas in Pyongyang last month.
The Trump administration appears concerned that the two leaders are getting too friendly as it seeks to wring further concessions out of Kim - specifically, the irreversible dismantling of North Korea's nuclear weapons program.
A State Department spokesperson said the US and South Korea are committed to "close coordination on our unified response to North Korea".
He also said that there could "eventually" be a meeting on United States soil. Still, the lifting of the 2010 sanctions could offer at least some tangible benefits to the North.
Kang backtracked on her remarks after facing criticism from some conservative lawmakers that the sanctions can not be removed unless North Korea first apologized for the attack, a stance adopted by former South Korean governments.
According to Channel News Asia, Kim said, "President Moon will visit the Vatican on October 17 and 18 to reaffirm its blessing and support for peace and stability of the Korean Peninsula".

On Wednesday, Beijing's Foreign Ministry released a statement reading: "It is time to start considering the adjustment of the UN Security Council's sanctions regime against [North Korea]".
The May 24 measures include the South blocking North Korea's access to the Jeju Straight.
She suggested that USA demands for a full disclosure of North Korean nuclear assets - which Pyongyang has balked at providing - is a poor path to follow, citing how the last time a similar process took place, it disintegrated in 2008 over the issue of related verification protocols. Seoul's Unification Ministry said Tuesday that water being supplied to the office is being provided to the town's residents as well.
Foreign Ministry spokesman Noh Kyu-duk later clarified, saying the government would seek sanction exemptions "in the event they are necessary", citing previous sanction exemptions that enabled the invitation of North Koreans to the Pyeongchang Winter Olympics early this year, Bloomberg reported. He said the resumption of the water supply does not violate sanctions.
"There are also humanitarian considerations as the residents of Kaesong have to rely on the park's facility for water", Baik said.
The closure of the factory park had deprived Kaesong residents of what had been a steady supply of water and electricity.
The agreement calls for the creation of buffer zones along the Koreas' land and sea boundaries and a no-fly zone above the border to prevent accidental clashes.
