The Kolkata-Bangkok Highway, part of the Trilateral Highway project, aims to enhance connectivity between India, Myanmar, and Thailand, promoting trade and regional integration. Scheduled for completion by 2027, it will facilitate increased exports and imports, linking key cities in the three countries. Simultaneously, the Indian government has invested significantly in the North Eastern Region's road infrastructure, constructing nearly 10,000 kilometers of National Highways to improve connectivity and economic integration. This focus on infrastructure is expected to bolster trade ties and socio-economic development in the region. Additionally, Bangladesh's strategic location positions it as a key transit route for trade, particularly benefiting landlocked nations like Bhutan and Nepal through the BBIN initiative. Enhanced regional connectivity is projected to significantly contribute to economic growth, potentially increasing the combined GDP of the region by over $8.3 trillion by 2035.
