Ask what Korea is talking about.

North Korean leader Kim Jong-un has arrived in China's border city of Dandong via a newly opened bridge linking the two nations, according to a South Korean government source reported by Yonhap on Oct. 24. This marks his first visit to China in more than a year, as KBS World notes. The visit is being closely monitored by Seoul, with the government source confirming the arrival to Yonhap. Separately, Yonhap reports Kim called for the 'strongest army' in a speech to military commanders in Pyongyang, though this is a distinct event from the China trip.
