Glad you asked

This doesn't include their current border conflicts with India, which could potentially go hot.

Glad you listed, because that data shows apart from Sino Vietnamese almost half a century ago, PRC launched basically no wars of aggression, i.e. everything including SCS was territorial defense, i.e just. And if it was in chart form, the peace disease lull in last 30 years relative to PRC growth makes modern PRC rise the most unprescedently peaceful in modern history, borderline on absurdly serenity. Truly somehting to emulate. Can you believe those Eurocusk gave a Peace prize to Obama?
