Ask what Korea is talking about.

North Korean leader Kim Jong-un made a surprise visit to China on Saturday, arriving in the border city of Dandong via a newly opened bridge linking the two nations, Yonhap and Korea Times report. Kim met with Beijing's top political adviser and said he hoped to expand cooperation with China, according to Korea Times. The trip, days before the anniversary of Chinese troops entering the 1950-53 Korean War, was aimed at reaffirming historic 'blood ties' between the countries, Korea Times reports in a cover story. An editorial in Korea Times urges that Kim's visit 'must lead to restraint,' noting the peninsula's future cannot be understood through inter-Korean relations alone.
