evidence: India accepted Tibet as part of China through a 2003 agreement that saw a quid pro quo recognition by China of the Himalayan region of Sikkim as Indian territory. However, growing tensions since the deadly June 15 clash between the Chinese and Indian armies has led many in New Delhi to suggest that India play the "Tibet card" as retaliation to growing Chinese intransigence on the disputed boundary and beyond. [...] That, in turn, could pave the way for China de-recognizing Sikkim as Indian territory – or, more alarmingly from New Delhi’s point of view, Beijing asserting that all of Jammu and Kashmir, as well as Ladakh, are disputed territories. Note that China already considers Arunachal Pradesh as part of "South Tibet." As strident symbolism, last year it destroyed 30,000 world maps made in China for export for failing to mark the territory as such. [...] The Tibet card for India – beyond relatively staid diplomatic signalling – is limited. At the same time, the India-China history clearly demonstrates how frontiers for both countries remain major, shared vulnerabilities. Both realize this. Therefore, for the time being, mere optics – such as Wang’s visit to Tibet – will have to make up for the lack of genuine options that carry a bite.
