According to scholar Taylor Fravel, the competition to control the disputed land in Chumbi valley had played a key role in escalating tensions in these events. Fravel has argued that these incidents demonstrate the effects of China's "regime insecurity" on the use of force. He states that three factors in these clashes emphasized the role of "declining claim strength in China's decision to initiate the use of force" against India. First is the Indian Army's expansion of size after the 1962 war leading to the strengthening of its borders with China. Second is the apparent Indian aggression in asserting its claims near the border. Third is the Chinese perceptions of Indian actions, for which Fravel says that the most unstable period of Cultural Revolution in China, which coincided with these incidents, was a possible contributing factor. Fravel remarks that the Chinese leaders possibly magnified the potential threat from India due to the border-tensions and the perceived pressure from India to strengthen its claims across the border, and decided that a severe attack was needed.
