Throughout their histories, the Indian and Chinese civilizations were separated by the vast Tibetan plateau, limiting their interaction to sporadic cultural and religious contacts; political relations were absent. It was only after China’s annexation of Tibet in 1950-1951 that Han Chinese troops appeared for the first time on India’s Himalayan frontiers.
纵观其历史，由于印度和中国的文明被广阔的青藏高原隔开，相互之间的文化和宗教互动因而受到了限制；而两国之间几乎不存在政治关系。直到1950-1951年中国吞并了西藏之后，中国的汉族军队才第一次出现在喜马拉雅山的印度边境上。
