In a historic development, Sri Lanka has signed a major agreement with China’s Sinopec Company for the construction of a new oil refinery in Hambantota, marking the largest foreign investment received by the country during President Anura Kumara Dissanayake’s four-day state visit to China. The new refinery, with a capacity of 200,000 barrels of oil, is expected to significantly boost Sri Lanka's refining capacity and is slated to export a large portion of its production. The total investment in the project amounts to $3.7 billion.

The Hambantota Oil Refinery has been a long-discussed project in Sri Lanka’s history, with its roots tracing back over two decades. In 2002, under Prime Minister Ranil Wickremesinghe, the government identified the potential for a new port and associated infrastructure, including an oil refinery, as part of the "Regaining Sri Lanka" economic development program. However, it wasn’t until 2005, when then-presidential candidate Mahinda Rajapaksa promised to rebuild Hambantota’s economy, that discussions around the development of the port and refinery gained further momentum.

Despite numerous talks over the years, the actualization of the refinery project was delayed until 2017 when Sri Lanka began discussions with two Chinese companies for a $3 billion refinery in Hambantota. The project was designed to boost Sri Lanka’s refining capacity and attract significant international investment. However, talks failed to materialize into a definitive agreement.

In 2018, Sri Lanka explored a partnership with Iran for a refinery project and the modernization of its existing refinery. However, the re-imposition of U.S. sanctions on Iran created significant obstacles for the project. The following year, Sri Lanka proposed a new refinery in partnership with Singapore’s Silver Park International and the Omani Ministry of Oil and Gas. Despite initial progress, the Omani Ministry withdrew from the project, further delaying the initiative.

In 2023, amid Sri Lanka's financial crisis, the government had to cancel a $3.85 billion foreign-funded oil refinery project. However, the tides turned when, in November 2023, the Sri Lankan Cabinet approved a proposal from China’s Sinopec to construct a $4.5 billion refinery at the Hambantota Port. This project is set to become the largest foreign investment in Sri Lanka since the country’s economic crisis in 2022.

The new refinery is expected to significantly enhance Sri Lanka's energy infrastructure, given the limited capacity of the existing Sapugaskanda refinery, which has a daily capacity of only 3.8 million barrels. Sinopec, the world’s largest refiner by capacity, brings with it vast experience and a solid track record, having expanded operations in countries like Saudi Arabia and Russia. The Hambantota Port, strategically located near one of the busiest shipping lanes in the world, is rapidly evolving into a hub for international investment, especially with increasing involvement from Chinese companies.

This new refinery is poised to not only strengthen Sri Lanka’s energy infrastructure but also play a pivotal role in the country’s economic growth, creating much-needed jobs and boosting the region’s development.
