(4th LD) N. Korea's Kim arrives in China's Dandong via newly opened bridge

North Korean leader Kim Jong Un reportedly made an unannounced visit to the Chinese border city of Dandong on Saturday, according to government sources in Seoul and South Korean media reports. The trip took place via the recently opened New Yalu River Bridge, which officially opened last week, 12 years after its completion. North Korea and China did not disclose Kim's visit in advance.

Kim is expected to return to North Korea later on Saturday, according to South Korea's ruling Democratic Party. China is North Korea's largest trading partner and a crucial source of diplomatic, economic, and political support. Kim was reportedly greeted by Chinese Premier Li Qiang upon his arrival. The new four-lane bridge connecting China and North Korea was completed in 2014 but delayed due to a lack of infrastructure on the North Korean side.

This visit comes as world leaders prepare for November's APEC summit in China's Shenzhen, sparking speculation about a potential meeting between Kim and US President Donald Trump. The news also precedes an important gathering in Beijing on Monday, where Chinese President Xi Jinping and other top Communist Party officials will meet.

Analysts suggest that Kim's visit may have aimed to reaffirm economic cooperation and press China for quicker progress on commitments made during Xi's visit to North Korea earlier this year.
