Hambantota Port (officially the Magampura Mahinda Rajapaksa Port) is a deep-water harbour on Sri Lanka's southern coast, near the island's southernmost point and astride one of the world's busiest east–west shipping lanes between the Malacca Strait and the Suez Canal. Conceived under President Mahinda Rajapaksa and opened in phases from 2010, it was financed largely by loans from China's Export-Import Bank (China Exim Bank) and built by the China Harbour Engineering Company and Sinohydro. The project became internationally significant in December 2017 when the Sri Lankan government, unable to service the accumulating debt, signed a 99-year concession transferring roughly 70% equity and operational control to China Merchants Port Holdings for about US$1.12 billion. The port is now the most frequently cited case study in debates over China's Belt and Road Initiative (BRI) and the contested concept of "debt-trap diplomacy."
The transaction is structured as a long-term lease rather than an outright sale: China Merchants holds the controlling stake through joint ventures (Hambantota International Port Group and a services company), while the Sri Lanka Ports Authority retains a minority interest and nominal sovereignty over the land. The lease proceeds were used by Colombo to bolster foreign-exchange reserves, not to retire the original construction loans directly. Critics, including many Indian and Western strategic analysts, frame Hambantota as the archetypal example of Beijing extracting strategic infrastructure from an over-indebted partner; revisionist scholarship (notably work by Deborah Brautigam and a 2019 Chatham House study) argues the debt was predominantly owed to Western capital markets and the lease was a Sri Lankan policy choice to raise dollars, not a Chinese seizure.
Strategically, Hambantota sits within India's maritime backyard and feeds Indian anxieties about a Chinese "String of Pearls" encircling the subcontinent, alongside Gwadar in Pakistan and facilities in Djibouti, Myanmar and Bangladesh. New Delhi has repeatedly objected to Chinese naval visits, most prominently the docking of the research-survey vessel Yuan Wang 5 in August 2022, which India and the United States characterised as a dual-use intelligence platform. As of 2026 the port operates primarily as a commercial bunkering, transshipment and roll-on/roll-off hub, with no permanent Chinese military basing, though the agreement's clauses on military use and Sri Lanka's deepening fiscal dependence on China remain live concerns, especially after the 2022 Sri Lankan economic collapse and IMF bailout.
For the exam, Hambantota is tested across International Relations and current-affairs sections of UPSC (GS Paper II — India and its neighbourhood, effect of foreign policies on India's interests), the FSOT and China-focused diplomatic papers. The typical question angle asks candidates to evaluate "debt-trap diplomacy" critically — distinguishing the popular narrative from the documented debt composition — and to locate Hambantota within the BRI and Indian Ocean security architecture. Aspirants should be able to name the 2017 lease, the 99-year term, China Merchants Port Holdings, and the Yuan Wang 5 episode, and connect them to India's Necklace of Diamonds counter-strategy and SAGAR doctrine.
Example
In December 2017, Sri Lanka leased Hambantota Port to China Merchants Port Holdings for 99 years in exchange for about US$1.12 billion, a deal often cited as the textbook case of Chinese "debt-trap diplomacy."
Frequently asked questions
Because Sri Lanka, unable to service China Exim Bank loans used to build the port, leased it to a Chinese firm for 99 years in 2017. Critics argue Beijing engineered the indebtedness to acquire strategic assets, though revisionist scholars note much of Sri Lanka's external debt was owed to Western markets, not China.
