I found this backgrounder by Ankit Panda at The Diplomat on the several border disputes between India and China very interesting. You might as well.
This marks the first in a series of articles I’ll be authoring for The Diplomat outlining the various elements of this standoff. Though I’ll elaborate in successive articles, the dispute began in early June when Chinese People’s Liberation Army (PLA) engineers began constructing a road near the Indian border on a piece of territory disputed between China and Bhutan. India, perceiving this as an unacceptable change to the status quo with potentially serious strategic ramifications, crossed a settled and undisputed international border with its troops to block the PLA contingent from proceeding. The Chinese government was apoplectic about what it saw as an Indian incursion across a settled border into Chinese territory (in reality, disputed with Bhutan) and has given an ultimatum to New Delhi that no diplomatic solution can be found until Indian troops unilaterally withdraw from what Beijing sees as Chinese territory. India, in the meantime, is not budging. Both sides are gridlocked and tensions are rising.
I don’t believe that the most likely dispute that could result in the use of nuclear weapons is between North Korea and the United States. I think it’s either a dispute between India and Pakistan or between India and China.
