In April 2018, at a summit in Panmunjom, Kim Jong-un and Moon Jae-in signed a deal committing to finally seal peace between both Koreas by the end of the year. Both leaders also symbolically crossed each other's borders, marking it the first time a South Korean president cross the North border and vice versa. Kim stated that the North will start a process of denuclearization, which was supported by then U.S. President Donald Trump. The peace talks led to nothing, as North Korea continued forward with their nuclear program, despite former U.S. President Donald Trump boasting it as a considerable win.
