Trump is scheduled to attend the two-day G-20 summit to open in Osaka, Japan, on June 28. He plans to travel to South Korea as well during the upcoming Northeast Asia tour. No exact schedule has been announced yet, while observers expect him to visit Seoul on his way back home. Moon reiterated that he’s ready to hold the fourth summit with Kim at any time and that the decision is up to Kim. On Kim’s latest letter to Trump, Moon said he was aware of it in advance.

He was responding to a question from Laura Bicker, a BBC correspondent in Seoul, who moderated the post-address Q&A session joined by Norwegian Foreign Minister Ine Eriksen Soreide. Despite no formal dialogue between the two Koreas and between North Korea and the U.S., Moon said, such letters are being exchanged among their leaders. He said he knew of Kim’s plan to send the letter to Trump, and he was informed by Washington of it later as well. He said he was also briefed on its contents as the allies usually share such information. Now that the leaders continue to trade such “warm letters,” Moon said, dialogue momentum is being maintained.

However, he warned that it could lose steam if the current, apparent stalemate in denuclearization and peace talks is further drawn out. “I am calling for an early meeting between Chairman Kim and President Trump,” he said. In Korea, the North’s leader delivered his condolence message and flowers to the bereaved family of Lee via his younger sister, Kim Yo-jong, who is a senior Workers’ Party official. Kim said Lee’s dedication and efforts for peace have become a “precious foundation” for the ongoing inter-Korean relationship, which is “moving toward the path of self-reliant unification, peace and prosperity.”

Addressing the conference at the University of Oslo, Moon presented his longer-term peace vision, a follow-up to his landmark Berlin speech in 2017, in which he proposed a new peace initiative for the peninsula. He vowed non-stop efforts to resolve “structural violence” that Koreans have suffered due to division. “Norway has never faltered on the journey for peace, as evidenced by the peace that exists today. Likewise, the Korean government will stride forward unwaveringly, to achieve peace without fail,” he said. He referred to the “positive peace” concept formulated by a famous Norwegian sociologist, Johan Galtung. “It is important to peacefully resolve the structural violence that the people of the two Koreas have suffered because of division,” he said. “I would like to name it as ‘peace for the people.'”

The two Koreas must first address the damage frequently reported in their border areas, especially in and around the Demilitarized Zone (DMZ), Moon said, adding that the “permanent legations” laid out in the 1972 German Basic Treaty can be an example. East and West Germany “took advantage of these permanent legations to make swift and joint responses to fires, floods, landslides, infectious diseases, insect damage and water contamination occurring in border areas,” he noted. What is most important is to deepen mutual understanding and trust, thus strengthening the will for dialogue, the president said. He underlined the significance of broadening public support for the peace initiative on the basis of the people’s confidence that they will benefit from it. “If we are to bring together positive thinking that peace is a good thing that improves the quality of life, it will heal the division in the hearts of people who have been separated by different ideology and views,” he said.

Moon noted that bringing lasting peace to Korea is no easy task. “The time needed will not be short. However, when mutual understanding allows enmity to dissolve, like the snow that melts and flows to the ocean, peace on the Korean Peninsula will also reach its goal,” he said. He arrived in Oslo Tuesday evening after a three-day state visit to Finland.

He is the first South Korean president to pay a state visit to Norway, as the two sides commemorate the 60th anniversary of forging bilateral diplomatic ties. King Harald V of Norway greeted Moon and first lady Kim Jung-sook in an official welcoming ceremony in Oslo earlier Wednesday. They laid a wreath at a monument for World War II victims and another one to mark Norway’s participation in the Korean War at Akershus Fortress. The Nordic nation sent a 623-member medical support team to Korea during the 1950-53 conflict. Operating the Norwegian field hospital known as NORMASH, it provided treatment for more than 90,000 soldiers and civilians. Moon then had a 30-minute meeting with Storting President Tone Wilhelmsen Troen. The Storting is the supreme legislature of Norway.

The president said that the role of the parliament, which fully reflected what the people want, is believed to be the driving force for Norway’s democracy, inclusive growth, welfare and gender equality, according to Moon’s spokesperson, Ko Min-jung. Troen said women are a big asset in her country, adding that females account for 40.8 percent of the legislators. In response, Moon said gender equality is an inevitable task for South Korea, especially as it’s entering an aged society. Moon is slated to head to Sweden on Thursday after traveling to Bergen, Norway’s second-largest city, where the home port is located for the navy’s 26,000-ton logistics and support ship built by South Korea’s Daewoo Shipbuilding & Marine Engineering.
