President Moon Jae-in plans to send a pot of orchids to the main opposition People Power Party's presidential candidate, Yoon Seok-youl, early next week to congratulate him on his nomination, a presidential spokesperson said Thursday.

The orchids will be delivered by Lee Cheol-hee, senior presidential secretary for political affairs, during a meeting between Lee and Yoon on Monday, presidential spokesperson Park Kyung-mee said.

Also on Monday, Moon will send orchids of congratulations to Kim Dong-yeon, a former finance minister who has declared an independent presidential bid, and Ahn Cheol-soo, the candidate of the minor opposition People's Party, Park said.

On Tuesday, Moon will send orchids of congratulations to Sim Sang-jeung, the candidate of the minor progressive Justice Party, Park said.

South Korea will hold a presidential election on March 9 next year. (Yonhap)
