Peng Liyuan
In March 2018, the Kim family's train was reportedly sighted in Beijing, which, along with heightened security around the Chinese government's Diaoyutai State Guesthouse led to speculation that Kim Jong-un and his wife Ri Sol-ju were visiting China. This was confirmed when they met with General Secretary of the Communist Party Xi Jinping and his wife Peng Liyuan. This marked the first time that North Korea's leader had left the country since taking the power in 2011.
