North Korean leader Kim Jong-un says he believes his meeting with US President Donald Trump could produce “great achievements,” according to a report by Seoul-based SBS TV.

SBS was quoting a statement by Kim Eui-kyeom, a South Korean presidential spokesman, on Friday. The Blue House spokesman says he received word on Kim Jong-un’s hopes for the historic meeting from Chung Eui-yong. Chung is the South Korean envoy who delivered the North Korean leader’s invitation for denuclearization talks to Trump on Thursday.

During their meeting at the White House, Chung reportedly told Trump that Kim expressed optimism for US-North Korea dialogue, saying he hoped it would be held “as early as possible.”

The envoy said that Kim spoke candidly during their discussion in Pyongyang earlier this week, when the North Korean leader unexpectedly offered to freeze the regime’s nuclear and missile testing as well as negotiate denuclearization.

“We must avoid repeating mistakes of the past, but I hope the US will accept our judgment on Kim and not pass up this opportunity,” Chung is said to have told Trump, according to Yonhap.
