If history is any indication, three speculations can be made for war between the US and China: World War III, Cold War 2.0, and regional proxy wars.
The second form of war is Cold War 2.0, which is being hotly debated as the closest to the current realities.
It is more about a trade war, currency war, technological war, cyber war or even hybrid war that combines elements of some or all of these.
But if Cold War 2.0 does exist, it would be a limited version of Cold War 1.0 with fewer fronts and features owing to China’s reluctance to take global leadership on every front as the former Soviet Union tried to do vis-à-vis the US.
For the Mekong region, the likelihood of Vietnam War 2.0 cannot be ruled out while China and Vietnam keep confronting each other in the South China Sea.
