Ask what Korea is talking about.

North Korean leader Kim Jong-un arrived in China's border city of Dandong on Saturday via a newly opened bridge linking the two nations, according to a South Korean government source cited by Yonhap. The visit is his first to China in more than a year, KBS World reports, and a ruling party source told Yonhap that Kim appears to be planning to return home later the same day. Korean media are leading with the surprise nature of the trip and the use of the new bridge, though no further details on the visit's purpose have been released.
