1. Introduction
The term “String of Pearls“ refers to China’s strategic initiative to expand its influence through a network of military and commercial facilities along the sea lanes from the Chinese mainland to Port Sudan in the Horn of Africa. Coined by Booz Allen Hamilton in a 2005 report for the U.S. Department of Defense, the phrase has since been widely used in defense and policy circles, particularly in the United States and India, to describe perceived Chinese efforts to secure maritime routes and project power across the Indian Ocean region.
2. Origins of the Concept
The phrase originated from the 2005 report “Energy Futures in Asia”, which highlighted China’s increasing dependence on imported energy resources and the strategic necessity of protecting its sea lines of communication (SLOCs). Given that over 80% of China’s oil imports pass through the Strait of Malacca, the country has sought to develop facilities that can serve both economic and strategic purposes along this route.
3. Key Components: The “Pearls”
The “pearls” are typically ports, airfields, surveillance installations, and diplomatic ties in various countries across the Indo-Pacific. China has built or invested in ports surrounding the Indian subcontinent, creating a geopolitical “arc” around India:

- Gwadar Port, Pakistan: Developed with Chinese funding and operated by a Chinese firm, Gwadar is strategically located near the Strait of Hormuz. It offers China access to the Arabian Sea and an alternative route for energy imports via the China-Pakistan Economic Corridor (CPEC).
- Hambantota Port, Sri Lanka: Leased to China for 99 years after Sri Lanka was unable to repay its loans, Hambantota has raised concerns about China’s use of debt diplomacy to gain strategic footholds.
- Chittagong Port, Bangladesh: Although not a Chinese military base, China has invested significantly in infrastructure development here, enhancing its economic and diplomatic influence.
- Kyaukpyu Port, Myanmar: Located on the Bay of Bengal, this port is part of the China-Myanmar Economic Corridor, which includes pipelines transporting oil and gas directly to Yunnan province in China.
- Djibouti Naval Base: China’s first overseas military base, established in 2017, supports anti-piracy operations and secures Chinese interests in East Africa and the Middle East.
- Port Sudan, Sudan: Chinese companies have invested in port development here, with future possibilities of dual-use facilities.
4. Strategic Objectives
China’s maritime strategy via the String of Pearls has several key objectives:
- Energy Security: To protect vital shipping routes that transport energy resources from the Middle East and Africa.
- Naval Projection: To expand the People’s Liberation Army Navy (PLAN)’s ability to operate far from home waters.
- Economic Influence: To deepen China’s role in global maritime trade through infrastructure development under the Belt and Road Initiative (BRI).
- Geopolitical Leverage: To counterbalance U.S. naval dominance and India’s influence in the Indian Ocean region.
5. Perceptions and Criticism
- India views the strategy as an attempt to encircle it militarily, often referring to this as the “strategic encirclement” doctrine.
- The United States sees it as part of a broader push by China to challenge the liberal international order and expand its naval presence globally.
- China, on the other hand, insists that its activities are purely economic, aimed at development and connectivity, not military expansion.
6. Recent Developments and the Evolving Nature
Recent scholarship suggests the String of Pearls is evolving from a metaphor into a more formalized maritime strategy, especially with China’s growing naval capabilities. Some experts argue it is better viewed within the framework of China’s Maritime Silk Road (part of the BRI), which integrates trade, infrastructure, and strategic interests under a unified geopolitical vision.
Others argue the term “String of Pearls” is somewhat outdated and oversimplifies China’s approach, which combines both “hard power” assets (e.g., bases) and “soft power” tools (e.g., diplomatic influence and development aid).
China’s “String of Pearls” strategy is widely viewed as a form of strategic containment of India, particularly in the Indian Ocean Region (IOR). While China officially frames this strategy in economic and developmental terms, its underlying geopolitical effects are significant—especially for India, which sees it as a challenge to its regional dominance.
7. Threat to Indian Naval Supremacy in the IOR
India traditionally enjoys geostrategic dominance in the Indian Ocean, with naval bases in the Andaman & Nicobar Islands and strong regional relationships. However, China’s growing presence threatens this:
- The Chinese Navy (PLAN) has increasingly conducted anti-piracy missions, joint drills, and submarine deployments in the Indian Ocean.
- India fears that in a conflict scenario, China could block or restrict India’s maritime movement or trade, particularly through chokepoints like the Strait of Malacca or the Laccadive Sea.
a. Diplomatic Leverage Over India’s Neighbors
Through investments and aid, China has increased its influence in countries traditionally within India’s sphere of influence—such as Nepal, Bhutan, Bangladesh, Sri Lanka, and Maldives.
- This undermines India’s neighborhood-first policy, making it harder for New Delhi to rely on regional diplomatic support in crises.
- For example, Sri Lanka and the Maldives have both allowed Chinese port calls or infrastructure development despite Indian concerns.
b. Strategic Diversion via Two-Front Challenge
China’s strategic alignment with Pakistan and expanding footprint in South Asia may open up two-front pressure on India—land border tensions in the north (Ladakh, Arunachal Pradesh), and maritime vulnerabilities in the south (Indian Ocean).
- The CPEC project running through Pakistan-occupied Kashmir adds another dimension to the India-China-Pakistan triangle.
c. Psychological and Strategic Signaling
The String of Pearls also acts as a form of strategic signaling, demonstrating China’s ability to operate far from its shores and challenge India’s assumption of dominance in its maritime backyard.
- It forces India to allocate more resources to maritime defense, stretching its military and economic capacity.
- The presence of Chinese submarines in Indian Ocean waters is viewed as a demonstration of hard power, with potential surveillance or blockade capabilities.
d. India’s Countermeasures
India is not passive and has responded in various ways:
- Naval modernization and expansion of the Andaman and Nicobar Command.
- Strengthening Quad (India, US, Japan, Australia) and partnerships with France and ASEAN states.
- Port development in Iran (Chabahar) and increased cooperation with Sri Lanka, the Maldives, and Bangladesh.
Conclusion
China’s String of Pearls strategy represents a significant shift in its foreign policy, reflecting ambitions that go beyond economic development to include strategic and military interests. Whether it is a deliberate encirclement strategy or an economic necessity remains a point of debate. What is clear, however, is that it has already reshaped geopolitical dynamics across Asia, the Indian Ocean, and East Africa.
While China insists that the String of Pearls is an economic endeavor aligned with the Belt and Road Initiative (BRI), its dual-use potential and geographical proximity to India signal a clear strategic intention to contain or constrain India’s regional ambitions. For India, maintaining influence in the Indian Ocean and counterbalancing China’s encirclement tactics remains a core national security objective.
