Genesis

Trigger

The arc was triggered by Sri Lankan Foreign Minister Vijitha Herath's announcement on March 15, 2025, during a parliamentary debate, confirming PM Modi's visit to finalize agreements reached during President Dissanayake's earlier trip to Delhi.

Why Now

The timing was driven by the need to stabilize Sri Lanka's economy post-crisis and the Indian government's urgency to secure maritime interests in the Indian Ocean Region (IOR) following increased Chinese naval activity.

Historical Context

This connects to the long-standing India-Sri Lanka Free Trade Agreement (ISFTA) of 2000 and the historical diplomatic foundations established in 1948, moving past the period of 'disengagement' seen during the ethnic conflict years.

Key Turning Points

1. [2025-04-07] Signing of the Defence Cooperation Agreement and 7 MoUs

   It institutionalized India as Sri Lanka's primary security partner over China.

   Before: Ad-hoc military aid. After: Structured, multi-sectoral military and digital collaboration.

2. [2025-04-08] Inauguration of the Sampur Solar Power Project

   Marked a shift from fossil fuel dependence to green energy collaboration, tying Sri Lanka's grid to Indian expertise.

   Before: Energy dependence on varied global suppliers. After: Joint clean energy capacity building with India.

What Happens Next
