Olympics officials say they have "kept the door open" for North Korea to take part in the upcoming Winter Games in South Korea.
"Basically, the two sides will focus on the Olympics".
South Korea's delegation will be headed by Unification Minister Cho Myoung-gyon.
South Korean Foreign Minister Kang Kyung-wha will deliver a statement at 2 p.m. Tuesday, the ministry said Monday.
According to reports, Bach is scheduled to meet Chang Ung, a member of the North Korean Olympic body at the IOC headquarters in Lausanne to discuss North Korea's possible participation in the games. But North Korea could demand some rewards in exchange for those steps, such as the revival of stalled cooperation projects that are lucrative for the North or the suspensions of annual U.S.
"We welcome the discussion which will take place ... between the governments of the Republic of Korea (ROK) and the Democratic People's Republic of Korea (DPRK)", the International Olympic Committee said.
But US ambassador to the United Nations Nikki Haley said that there was "no turnaround" in the US stance, reiterating that the North must stop nuclear tests for talks with Washington. The North's delegation will cross the border at around 9:30 a.m. and walk to the meeting venue on the South side of Panmunjom.
Moon's government wants North Korea to participate in the February 9-25 games in Pyeongchang, South Korea, in hopes of reducing animosities between the rivals, which are separated by the world's most heavily fortified border.
On July 17, 2016, the South proposed holding military talks on easing border tensions, and a Red Cross meeting to discuss reunions of divided families.
The drills' suspension is something that South Korea can not accept in consideration of its relations with the US, its main ally, which is seeking increased pressure and sanctions on the North.
She said the United States is "not letting up on the pressure" to end North Korea's nuclear weapons development and warned, "We can destroy them, too".
Kim is suspected of having orchestrated Pyongyang's two deadly attacks on the South in 2010 - the sinking of the Cheonan warship and the shelling of Yeonpyeong Island.
The dispute over "comfort women" - a euphemism used to refer to women mostly from Asian countries who worked in brothels built to provide sex to Japanese soldiers during World War II - has been one of the major issues that have strained ties between Tokyo and Seoul for years.
During a different Sunday talk show interview, CIA Director Mike Pompeo also came to the president's defense, telling Fox News that the nuclear button tweet was "entirely consistent with what we're trying to communicate" to the North Korean leader.
In that same speech, Kim added that North Korea would continue "mass producing" nuclear weapons, which prompted a response from Trump in which he mocked Kim by stating that the U.S. nuclear button was "much bigger & more powerful", and that his button "works".
