Lip readers have reportedly attempted to interpret what South Korean President Moon Jae-in and North Korean leader Kim Jong Un discussed during a recent meeting.

South Korean news outlet Chosun Ilbo reported that the conversation between the two leaders was recorded, but no audio is available. The publication then asked three lip readers to try to decode the conversation.

The lip readers acknowledged the difficulty in interpreting the conversation from such a distance, but said Kim repeated the words “U.S.,” “Trump” and “nuclear weapons.”

They also found the North Korean leader said his upcoming summit with President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE “must yield positive results” and that he wants to take things “step-by-step.”

“The comments appear to have been made while the two leaders were talking about the U.S.’ suspicions about North Korea’s willingness to scrap its nuclear weapons,” the lip readers said.

Kim and Trump are expected to meet in the coming weeks as the U.S. pushes for the denuclearization of North Korea. Trump said Tuesday a date and location for the meeting will be announced in the next "couple of days."

Trump has floated Singapore and the Demilitarized Zone separating North and South Korea as possible meeting locations.

North Korea has reportedly offered to end its nuclear program if the U.S. agrees not to invade the country in the future. However, some are skeptical of the offer, noting North Korea has previously made such overtures without following through.
