This undated picture released by the ROK's presidential Blue House on April 24, 2018 shows a cake decorated with a garnish in the shape of a unified Korean peninsula, which will be served at the dinner of the upcoming inter-Korean summit. The cake is in a wooden bowl, a symbol of Cold War confrontation, which will be broken by a hammer to symbolize the start of reconciliation. "Spring of the Korean people", the slogan reads.
