Xi's visit to Pyongyang reflects shifting balance of power in Northeast Asia: Analysts

China and North Korea have signalled a renewed push to boost ties, as Chinese President Xi Jinping concludes his first trip to Pyongyang in nearly seven years.

But Russia's growing ties with Pyongyang have changed that dynamic, with military cooperation and trade reducing North Korea's reliance on Beijing. China remains North Korea's largest trading partner. Lim Yun Suk reports from Seoul.
