Detailing the Indian intervention in Sri Lanka this chapter provides a list of policy requests from New Delhi to Colombo and the rate of Sri Lankan compliance from 1986 to 1989. Providing a summary of the Indian-Sri Lankan counterinsurgency partnership, this chapter discusses several distinctive components of the alliance, including the unique dynamics of New Delhi initially supporting the Tamil insurgents to later sending troops into Tamil regions of Sri Lanka to fight Tamil separatists alongside representatives from the Sri Lankan regime in Colombo. An overestimation of its ability to coercively influence both the Tamil insurgents as a proxy faction and the government in Colombo as a proxy ally backfired, costing New Delhi both politically and militarily. Overall, similar to other interventions, local compliance was affected by the convergence or divergence of Indian and Sri Lankainterests, interacting with Indian dependency on Colombo to implement particular policies. There are 79 Indian policy requests to Colombo identified and detailed, including electoral, law enforcement, and governance policies as well as policies to address Tamil grievances.
