President Moon has invited the leaders of Korea's five political parties for a dinner at the Blue House on Sunday.
The president wants to thank them for attending his mother's funeral and offering their condolences.
They're also likely to discuss various state issues regarding the economy, diplomacy and society.
And with the gathering coming right after President Moon enters the half-way point of his presidency on Saturday, he's expected to ask for the parties' support for his policies.
The gathering will be the first such meeting since July, when they met mainly to discuss Japan's export curbs.
