For more on the Korean Peninsula tension, we are now joined in studio by Su Xiaohui, Deputy Director of the Department of International and Strategic Studies at the China Institute of International Studies. Welcome.

Q1. It seems to be a vicious circle where both sides are provoking each other. How well is the US-South Korea alliance containing Pyongyang?
