North Korean leader Kim Jong-un has arrived in China's border city of Dandong via a newly opened bridge linking the two nations, a South Korean government source told Yonhap on Saturday. The bridge formally opened on Oct. 15, and this marks Kim's first visit to China in 13 months and his sixth overall, according to Yonhap and KBS World reports. The visit is described as a surprise, with Kim crossing into Liaoning Province's Dandong.
