Engraved on the stone plaque for the tree will be the phrase, “Peace and Prosperity Are Planted,” as well as the signatures of the leaders. After the tree-planting, the two plan to stroll together to a footbridge where a signpost for the military demarcation line stands, Im said. The leaders will meet again in the afternoon and later attend a banquet, Im said. Im said Kim is to be accompanied by nine top North Korean officials, including his influential sister, Kim Yo Jong. Im said South Korea hopes Kim’s wife, Ri Sol Ju, will attend parts of Friday’s summit, but Ri’s attendance hasn’t been agreed to yet. It’s also not clear how the leaders will announce the results of the summit. The most difficult part, Im said, centers on North Korea’s level of denuclearization commitment. Friday’s summit and Kim’s planned meeting with President Donald Trump in May or early June were arranged after Kim recently expressed a wiliness to put his nuclear program up for negotiation after a year of nuclear and missile tests.
