On Thursday, Trump suggested in an interview with The Wall Street Journal that he could have a good relationship with Kim, though he was vague about the extent of his dealings with the North Korean leader.
"The participants will be a delegation from the PyeongChang 2018 Organising Committee and delegations from the (Olympic committees) of the Republic of Korea and the Democratic People's Republic of Korea (North Korea), all led by their respective presidents, as well as high-ranking government officials and the IOC members in both countries", the IOC said.
There were also talks of carrying out a limited strike on North Korea with the fears of a nuclear war in the background.
According to the US President, "all these harsh comments were part of a strategy".
The White House said Wednesday that Pence will attend the opening ceremonies of the games, scheduled for February 9 in Pyeongchang, South Korea.
"President Trump expressed his openness to holding talks between the United States and North Korea at the appropriate time, under the right circumstances", the White House statement said. If they march separately, the South Korean team would massively outnumber the North Koreans. "I think you people are surprised".More news: Donald Trump's 'racist slur' provokes outrage

South Korea had been campaigning for its infamous peninsula partner to attend the Winter Olympics in an apparent effort to reconcile differences, or at least calm concerns regarding the North's worldwide disputes over missile launches and nuclear weapons.
Analysts say South Korea could find itself in a tight spot, sandwiched between its desire to improve ties with Pyongyang and to work with Washington to denuclearise the North.
North Korea propaganda outlet Uriminzokkiri stated Friday the United States agreed to postpone military exercises until after the Winter Games, and credited the development to the Kim Jong Un regime.
'Who knows where it leads?'
The latest discrepancy between the readouts of Trump and Moon's call may reveal that South Korea is pushing back on the pressure, which sometimes entails loose talk of putting South Korean lives at risk.
The Blue House also revealed that Trump is supposedly open to talks with North Korea.
South Korea's Foreign Ministry had indicated it would consider lifting some sanctions temporarily to facilitate the North's attendance in the Games, to be held from Feb 9 to 25 in the alpine county of Pyeongchang.
