China's Involvement in Reviving Bangladesh's Lalmonirhat Airbase: Strategic Implications for India

China's reported assistance in reviving the World War II-era Lalmonirhat airbase in Bangladesh has raised significant strategic concerns for India. Located merely 12-15 kilometers from the Indian border and approximately 135 kilometers from the vital Siliguri Corridor—India's narrow land link connecting its northeastern states to the mainland—the development is viewed with apprehension by Indian defense analysts. 

Historical Context of Lalmonirhat Airbase

Established in 1931 by the British as a military airbase, Lalmonirhat played a crucial role during World War II. Post-independence, it remained under the control of the Bangladesh Air Force but has been largely inactive for decades. Recently, the site has been repurposed to host the Bangladesh Aviation and Aerospace University.

China's Role and Strategic Concerns

The current interim administration in Bangladesh, under Chief Adviser Mohammad Yunus, has reportedly sought Chinese assistance to redevelop the Lalmonirhat airbase. While officially presented as a civilian infrastructure project, Indian defense experts express concerns over its potential dual-use nature, fearing it could be adapted for military logistics, surveillance, or force deployment. 

The proximity of the airbase to the Siliguri Corridor amplifies these concerns. This corridor, often referred to as India's "Chicken's Neck," is a 22-kilometer-wide stretch that serves as the sole land connection between India's northeastern states and the rest of the country. Any strategic developments near this corridor are closely monitored by India due to the potential risks of isolation of the northeastern region. 

Broader Geopolitical Implications

China's involvement in Bangladesh's infrastructure projects is seen as part of its broader strategy to expand influence in South Asia. Beyond the Lalmonirhat airbase, Chinese companies are engaged in various economic projects near the Indian border, including factories and energy plants. This multifaceted engagement aligns with China's "string of pearls" strategy, aiming to establish a network of strategic assets in the region.

Additionally, the potential collaboration between China and Pakistan in Bangladesh adds another layer of complexity. Recent visits by Pakistani officials to Bangladesh have raised concerns about renewed intelligence activities and the possibility of strategic encirclement of India.

India's Response and Strategic Measures

In light of these developments, India has taken steps to bolster its defense infrastructure in the northeastern region. The Indian Army has enhanced security measures in the Siliguri Corridor, deploying advanced military assets, including Rafale fighter jets, BrahMos missiles, and S-400 air defense systems. These measures aim to ensure rapid mobilization and readiness to counter any potential threats.

Furthermore, India is expediting the Kaladan Multi-Modal Transit Transport Project, which connects the northeastern state of Mizoram with Myanmar, providing an alternative route to the mainland. This initiative seeks to reduce dependency on the Siliguri Corridor and enhance strategic resilience. 

The revival of the Lalmonirhat airbase with Chinese assistance underscores the shifting geopolitical dynamics in South Asia. For India, it highlights the need for vigilant monitoring of regional developments and proactive measures to safeguard its strategic interests, particularly concerning the vulnerable Siliguri Corridor. Strengthening diplomatic ties with neighboring countries and investing in alternative connectivity projects remain crucial components of India's strategy to maintain regional stability and security.
