At a funeral last week in the mountains of northern India, one of Prime Minister Narendra Modi¡¯s top aides paid respect to a Tibetan soldier killed on the front lines of deadly clashes with China.

Surrounded by troops waving the flags of both India and Tibet, Ram Madhav laid a wreath before the coffin during a ceremony that gave the deceased man full military honors. In a now-deleted tweet, the national general-secretary of Modi¡¯s ruling Bharatiya Janata Party said he hoped the soldier¡¯s death would lead to peace along the ¡°Indo-Tibetan border.¡±

The rare recognition of a secretive Indian military unit with Tibetan soldiers by itself threatened to escalate a border dispute that has killed dozens since May and tanked economic ties between the world¡¯s most-populous nations. Even more significant was the suggestion that India questioned China¡¯s sovereignty over Tibet ¡ª a red line for Beijing, which sees separatism as a cause also worth fighting for in places from Xinjiang to Hong Kong to Taiwan.
