How does connectivity infrastructure like the Kaladan Project and Trilateral Highway advance India's Act East Policy?

The Act East Policy seeks to convert India's Northeast from a landlocked periphery into a bridgehead to ASEAN. The Kaladan Multi-Modal Transit Transport Project and the 1,360-km India–Myanmar–Thailand Trilateral Highway are its physical spine, translating diplomatic intent into hard connectivity [1][2].

Overcoming the Northeast's geographic isolation

• Kaladan links Kolkata/Haldia port to Zorinpui in Mizoram via Myanmar's Sittwe port and the Kaladan river up to Paletwa, offering an alternative to the narrow Siliguri corridor [1].
• The first Indian cargo ship docked at Sittwe in May 2023, marking operational proof of concept [1].

Economic integration with ASEAN

• The Trilateral Highway runs Moreh (Manipur) to Mae Sot (Thailand) via Myanmar; India is building the 120.74-km Kalewa–Yagyi section and 69 bridges on the 149.70-km Tamu–Kyigone–Kalewa stretch [2].
• These corridors shorten trade routes to Southeast Asia and make the Northeast a production and transit hub rather than a terminal market.

Strategic and diplomatic leverage

• Both projects were flagged for early completion at the 23rd India–Myanmar National Level Meeting (July 2026), where India underlined Myanmar's place in Neighbourhood First, Act East and MAHASAGAR [3].
• Sustained Indian investment offers Myanmar a development alternative and preserves India's strategic space in the Bay of Bengal.

Constraints

• Myanmar's internal conflict has stalled the Paletwa–Zorinpui and Myanmar highway segments; insurgent sanctuaries persist along the 1,643-km border [4].
• Security tightening, including scrapping the Free Movement Regime and full border fencing, must be balanced against trade facilitation and cross-border kinship ties [4].

Connectivity thus operationalises Act East by fusing economic integration, Northeast development and strategic depth into a single instrument. The way forward lies in phased completion insulated from Myanmar's political flux, paired with border haats, integrated check posts and a calibrated movement regime — so that "Act East" is realised as "Act Fast East", anchoring the Northeast in India's Indo-Pacific vision.
