SEOUL, May 27 (Xinhua) -- South Korean President Moon Jae-in said Sunday that both top leader of the Democratic People's Republic of Korea (DPRK) Kim Jong Un and U.S. President Donald Trump wished the success of their summit, originally scheduled for June 12 in Singapore, "wholeheartedly."

Moon made the comments in his nationally televised speech after holding a surprise summit with Kim on Saturday at the border village of Panmunjom and a summit with Trump in Washington earlier this week.

The South Korean leader said he met with Kim for the second time in a month following the third-ever inter-Korean summit on the South Korean side of Panmunjom on April 27.

The second meeting between Moon and Kim was held on the DPRK side of Panmunjom at the request of Kim, Moon said.

U.S. President Trump sent a letter to the DPRK leader on Thursday, saying that their planned meeting in Singapore on June 12 would not happen due to "tremendous anger and open hostility" displayed in Pyongyang's recent statements.
