First, power asymmetries matter. When countries are evenly matched, it is less risky for them to talk while fighting because it is less clear who the “loser” is. This is why wars between great powers and smaller countries continue for a long time, contrary to expectations.
The Vietnam War is a perfect example. During the three years that followed its entrance into the war, the US tried to engage in talks with the North Vietnamese, supporting more than 2000 attempts to open direct talks without preconditions. North Vietnam either ignored or rejected every single attempt and made no offers of its own, for fear of looking weak.
While India does enjoy some local advantages, Chinese conventional military power is superior to that of India. If China enjoys undisputable operational success, Beijing will likely offer talks quickly to the Indian side. China would do so to lock in any territorial gains with a peace agreement if India agrees and looks reasonable in the international community’s eyes if New Delhi refuses. India’s calculations will likely be the opposite. Rhetoric on how China believes India to be weak, and the need to stand up to Chinese aggression, will surge. Any Indian politician that suggests talking with the Chinese will be attacked.
In other words, unless India is squarely defeated and thus cannot continue to fight, or China decides to withdraw unilaterally again, the war may drag on for longer than either side wants.
The degree to which outside powers get involved will also impact the diplomatic dynamics in a hypothetical war. If the US supports India, China may be less reluctant to engage in diplomacy. This is because Beijing’s focus will shift to signalling strength to the US. In general, the more China can link Indian military progress to the US, the more likely it will react strongly and negatively. Therefore, to minimise China’s reaction, the US should think of ways to support India without being involved directly in operations.
Russia is unlikely to get involved more directly, given its close ties to India and China, and will likely emerge as the central mediator if war breaks out. Russia’s role should be encouraged. My research shows that outside mediators can help bring belligerents to the table because they can, first, serve as guarantors that belligerents are not dangling talks to probe each other’s positions, or second, provide independent positive inducements so that talks are not interpreted as a concession given under military pressure.
Complex calculations about how the enemy will interpret and respond to a willingness to talk create an extra obstacle to peace when wars break out. This means high costs even if the war stays at the conventional level, because it is likely to drag on. The other possibility is that the war ends quickly because China secures a decisive victory. But this scenario does not bode well for the future, either. it would leave the world with a weaker India and emboldened China.
There are many reasons all parties should avoid a second Sino-Indian border war – the costs of conversation are only one of many factors that would delay conflict resolution.
