President Moon Jae-in is set to host a private dinner for his rivals in the party primary for the presidential election, the presidential office Cheong Wa Dae said Wednesday.

The dinner will be held at the president's official residence at Cheong Wa Dae, involving Seoul City Mayor Park Won-soon and South Chungcheong Province Gov. An Hee-jung, according to a Cheong Wa Dae official.

"The president invited them to his official residence to express his gratitude for their support for party unity throughout the primary," the official told reporters, asking not to be identified.

The dinner, set to start later Wednesday, will also involve Seongnam City Mayor Lee Jae-myung and Goyang City Mayor Choi Sung, who had also sought the nomination of the Democratic Party in the May presidential by-election caused by the ouster of former leader Park Geun-hye earlier in the year.

All the participants are expected to be accompanied by their spouses, the Cheong Wa Dae official said. (Yonhap)
