A summit meeting was held between President Moon and his visiting Slovenian counterpart at the top office.
The liberal leader also sat down with Russian Athletes to provide encouragment, as they could not compete under their country's flag in the Pyeongchang games.
Hwang Hojun has more on the continued Olympic diplomacy.
South Korean President Moon Jae-in greeted his Slovenian counterpart, President Borut Pahor, at the Blue House on Tuesday where they held a summit meeting.
It was the first visit by a Slovenian President to South Korea since the two countries established diplomatic relations in 1992.
During the meeting, President Moon expressed his gratitude for President Pahor's visit during the Pyeongchang Winter Olympic Games and praised how the two countries have increased their trade by more than 20 fold in the past ten years.

I am very pleased that South Korea and Slovenia have developed a mutually beneficial and cooperative relationship, based on friendship, trust, and other shared values.

The two leaders agreed to enhance cooperation in various areas including logistics, noting that Korean companies are already using Slovenia's southwestern city of Koper as a gateway for shipments to central and eastern Europe.
They also agreed to exempt their respective nationals working in the other's country from having to pay into local social security programs -- rather, those contributions will be counted toward equivalent programs back in their home countries.
In addition, Presidents Moon and Pahor shared their views on boosting global efforts to denuclearize North Korea.
The Slovenian President said he admires President Moon's efforts to peacefully resolve the nuclear issue and expressed his desire to help achieve that.

"I would like to see much more involvement of European Union in this very, very important security and political issue that everybody is watching. I think we could be of more help than we are at the moment."

Shortly after the luncheon meeting, President Moon invited delegates representing the Olympic Athletes from Russia to the Blue House, as an act of encouragement.
Russian athletes are competing in Pyeongchang as individuals... after their national team was banned... over a state-sponsored doping scandal.
President Moon said he is grateful that Russia sent a large number of athletes despite the situation.
The Russian representatives delivered an invitation from President Vladimir Putin... for President Moon to visit Russia for football's World Cup later this year.
