SEOUL, April 17 (Yonhap) -- South Korea may send special envoys to North Korea if necessary to arrange or ensure the success of their summit next week, the presidential office Cheong Wa Dae said Tuesday.
"The possibility of sending the head of the National Intelligence Service (NIS) or National Security Office chief Chung Eui-yong always remains open if necessary while preparing for the summit," Cheong Wa Dae chief of staff Im Jong-seok told a press briefing.
Chung and the NIS chief, Suh Hoon, traveled to Pyongyang early last month as special envoys of South Korean President Moon Jae-in.
There, the two South Korean envoys held an unprecedented meeting with North Korean leader Kim Jong-un, who offered to meet the South Korean leader and U.S. President Donald Trump to discuss his country's denuclearization.
The Moon-Kim meeting is set to be held next Friday. Trump has said he will likely meet the North Korean leader in late May or early June.
Im said the Moon-Kim summit will be a historical event as it will be the first time for a North Korean leader to set foot on South Korean soil.
The third inter-Korean summit is set to be held on the South Korean side of the joint security area of Panmunjom inside the heavily-fortified demilitarized zone.
"It is an important point to us because depending on the outcome of the summit, it may lead to the establishment of regular dialogue (between the two Koreas) at Panmunjom," Im said.
Earlier, the unification ministry said 360 rounds of inter-Korean dialogue have been held at Panmunjom, accounting for more than half of 655 inter-Korean talks held since the division of the two Koreas at the end of the 1950-53 Korean War.
Inter-Korean dialogue was suspended for years under two conservative South Korean administrations. Talks resumed at the start of this year after Pyongyang agreed to take part in the 2018 Winter Olympic Games held in South Korea.
Further portending continued dialogue, the two Koreas have agreed to establish a direct hotline between their leaders.
Im said the direct phone line will likely be set up Friday for possible trials before the inter-Korean summit.
