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 who spoke to Yonhap News Agency. The visit, his first to China in more than a year, included a meeting with Beijing's top political adviser, and state media later reported Kim vowed to promote the two countries' longstanding relationship forged in blood. Kim said he hoped to expand cooperation with China, as reported by the Korea Times.
