What Happened
- Mazagon Dock Shipbuilders Limited (MDL), a Navratna Defence Public Sector Undertaking (DPSU) under the Ministry of Defence, completed the acquisition of a 51% controlling stake in Colombo Dockyard PLC (CDPLC) — Sri Lanka's largest shipbuilding and repair facility.
- The deal was valued at approximately $26.8 million (₹249.5 crore), making it MDL's first international acquisition and establishing CDPLC as a subsidiary of the Mumbai-headquartered shipbuilder.
- The acquisition was executed through a tripartite agreement involving MDL, CDPLC, and Onomichi Dockyard Co. Ltd. of Japan, the previous majority shareholder.
- MDL acquired a 41.73% stake by purchasing unsubscribed rights shares from the Japanese company, and an additional 9.27% stake through a mandatory open offer under Sri Lanka's Takeovers and Mergers Code.
- Separately, CDPLC is developing an engineering workshop at the Hambantota International Port in southern Sri Lanka, giving India a presence at a port where China holds a 99-year lease.

Mazagon Dock Shipbuilders Limited (MDL)
MDL, headquartered in Mazagaon, Mumbai, is India's premier warship-building yard and the only shipyard in the country capable of constructing both destroyers and conventional submarines. It was taken over by the Government of India in 1960 and operates as a Navratna DPSU under the Ministry of Defence.
- Current projects: Project 15B (four destroyers), Project 17A (four frigates), Project 75 (six Scorpene-class submarines — three delivered)
- Also builds offshore platforms and support vessels for the oil sector
- The Colombo Dockyard acquisition is MDL's first overseas footprint, signalling a shift from purely domestic shipbuilding to a regional maritime services role
- Located in Port of Mumbai — India's oldest and most strategically positioned naval shipyard
Connection to this news: MDL's acquisition transforms it from a purely domestic shipbuilder into a regional maritime enterprise with a strategic presence in the Indian Ocean, directly supporting India's net security provider ambitions.
India's SAGAR Doctrine and Indian Ocean Strategy
India's SAGAR (Security and Growth for All in the Region) doctrine was announced by Prime Minister Narendra Modi in March 2015 during his address to the Indian Ocean Rim Association (IORA). It outlines India's vision of being the preferred security partner and net security provider for Indian Ocean littoral states. In 2025, this was broadened into the MAHASAGAR initiative to include deeper economic and geopolitical engagement.
- SAGAR's five pillars: economic cooperation, collective security, sustainable development, maritime domain awareness, and disaster risk reduction
- India maintains surveillance through the Information Fusion Centre – Indian Ocean Region (IFC-IOR) at Gurugram, with data linkages from partner navies
- India's naval assets are deployed at key chokepoints: Strait of Malacca, Strait of Hormuz, and Gulf of Aden
- India has signed White Shipping Agreements and bilateral maritime security pacts with over 50 nations
Connection to this news: The Colombo Dockyard acquisition is a concrete operationalisation of the SAGAR doctrine — India is not just patrolling the Indian Ocean but embedding economic and infrastructure presence in key littoral states to build durable strategic relationships.
China's String of Pearls and Hambantota
China's "String of Pearls" refers to a network of commercial ports and military-use infrastructure across the Indian Ocean, stretching from the South China Sea to the Arabian Sea, aimed at securing Chinese sea lanes and encircling India. Sri Lanka's Hambantota port, built with Chinese loans, was leased to a Chinese state-owned company for 99 years in 2017 — the most cited example of "debt-trap diplomacy."
- China's string includes Gwadar (Pakistan), Hambantota (Sri Lanka), Kyaukpyu (Myanmar), Chittagong (Bangladesh), and Djibouti (East Africa)
- Hambantota lease: China Merchants Port Holdings — 99-year lease for 70% stake, signed 2017
- BRI (Belt and Road Initiative) port investments are the key instrument of China's Indian Ocean push
- India countered with ₹45,000 crore Sagarmala Programme for port-led development domestically, and strategic port investments abroad (Chabahar in Iran, Adu Atoll in Maldives)
Connection to this news: CDPLC is developing a workshop at Hambantota International Port — placing Indian maritime infrastructure at the very location China uses as its primary foothold in Sri Lanka. The MDL acquisition directly counters Chinese influence at Hambantota and in Colombo.
