The “Necklace of Diamonds” strategy is a geopolitical and economic concept that refers to India’s strategic partnerships and influence along key maritime trade routes and ports in the Indian Ocean Region (IOR). Coined in response to China’s “String of Pearls” strategy, which involves developing ports and infrastructure in the Indian Ocean for strategic advantage, the Necklace of Diamonds emphasizes economic diplomacy, trade security and regional development.
From an economic perspective, this strategy is significant because it enhances trade security, promotes regional connectivity, strengthens energy supply chains and attracts foreign investment. With the Indian Ocean accounting for over 70% of global oil shipments and 50% of container traffic, securing economic interests along these routes is crucial for India’s growth, energy security and regional leadership.
This article explores the economic angle of the Necklace of Diamonds strategy, its opportunities, challenges, arguments in favor and against and future implications, emphasizing the integration of geopolitical strategy with economic growth.
Understanding the Necklace of Diamonds Strategy
1. Definition and Origin
The Necklace of Diamonds strategy is an Indian geopolitical approach to secure its maritime interests in the Indian Ocean.
It involves building alliances, economic partnerships and infrastructure linkages with countries along the IOR, including Seychelles, Maldives, Sri Lanka, Mauritius, Madagascar and Vietnam.
The strategy is also aimed at countering China’s expanding influence, known as the String of Pearls, which consists of ports and naval facilities in strategic locations.
2. Key Components
Maritime Infrastructure Development – Ports, shipping lanes and logistics hubs.
Economic Diplomacy – Bilateral and multilateral trade agreements, investment promotion and joint ventures.
Energy Security – Securing oil and gas supply lines and alternative energy routes.
