This is a chapter in my book Armed Coexistence: The Dynamics of the Intractable Sino-Indian Border Dispute, published by Palgrave Macmillan.
In this chapter, poliheuristic choice theory is used to explain how the different leaders from Mao Zedong and Jawaharlal Nehru to Xi Jinping and Narendra Modi. Poliheuristic choice theory argues that a state leader chooses which foreign policy to pursue by relying on several heuristics, or rules of thumb, in order to determine what would likely be the best option. When it comes to interstate border disputes, the key heuristics that a leader will utilise are the impact a policy will have on their political survival, whether it would advance their grand strategy for the country and which policy would be most likely to work. This chapter then applies this basic model to explain the actions of the key state leaders in China and India.
