Operating in Beijing’s Backyard: INS Kulish at Ream Naval Base Resets Indo-Pacific Power

Naval Strategy · Indo-Pacific Geopolitics

By docking a missile corvette at Cambodia’s Chinese-refurbished naval stronghold, the Indian Navy demonstrates reciprocal maritime reach, providing Southeast Asia with a vital non-aligned security alternative.

Executive Brief

The arrival of the Indian Navy’s guided-missile corvette INS Kulish at Ream Naval Base on 13 September 2026 marks one of the boldest deployments of India’s Act East naval diplomacy (IANS Live, India Strategic). Located on the Gulf of Thailand, Ream was extensively upgraded with Chinese funding and scrutinized by Western defense planners as a prospective forward operating enclave for the People’s Liberation Army Navy (PLAN). By docking INS Kulish at Ream Naval Base, New Delhi punctures the narrative of exclusive Chinese maritime suzerainty, operationalizing its vision of India’s Military Power in 2026 by projecting blue-water reach directly into Beijing’s maritime perimeter.

1. The Geopolitical Crucible: Why INS Kulish at Ream Naval Base Matters

The deployment of INS Kulish at Ream Naval Base challenges the assumption that Chinese-financed infrastructure automatically creates exclusive military sanctuaries. By engaging Phnom Penh directly, India validates Cambodia’s constitutional neutrality while establishing an operational footprint adjacent to the South China Sea.

For over five years, Cambodia’s Ream Naval Base in Sihanoukville has been a focal point in Indo-Pacific security discourse. Upgraded through concessional Chinese grants, dredging works, and drydock installations, foreign analysts widely anticipated that Ream would serve as Beijing’s second overseas military outpost after Djibouti, providing the PLA Navy with an uninhibited flank in the Gulf of Thailand.

The presence of INS Kulish at Ream Naval Base disrupts this narrative. Armed with 16 Kh-35 Uran anti-ship missiles and Otobreda naval guns, the 1,400-tonne Kora-class corvette arrived not as a spectator, but as an active partner conducting joint operational exchanges and professional cross-deck training with the Royal Cambodian Navy. This deployment demonstrates that Southeast Asian capitals actively seek diplomatic diversification to avoid single-nation hegemony.

2. Reciprocal Maritime Geopolitics: Balancing Beijing’s Indian Ocean Footprint

China’s regular dispatch of oceanographic survey vessels and naval combatants to Sri Lanka, Pakistan, and the Maldives has met an assertive Indian response: projecting reciprocal naval presence directly into Southeast Asian chokepoints.

3. Defence & Markets Crossover: Expanding Indian Naval Exports to ASEAN

Forward port visits by operational combatants function as live demonstrations of Indian shipbuilding reliability, paving the way for domestic shipbuilders and electronics primes to capture Southeast Asian defence modernization contracts.

The successful mission of INS Kulish at Ream Naval Base has immediate commercial ramifications across India’s expanding defence export ecosystem:

  • Shipyard Export Portfolios: Indian public and private shipyards (Garden Reach Shipbuilders & Engineers, Goa Shipyard, L&T Shipbuilding) are aggressively bidding for offshore patrol vessel (OPV) and fast interceptor craft tenders across ASEAN. Demonstrating operational reliability in Southeast Asian waters validates Indian hull designs and mechanical survivability.
  • C4ISR & Coastal Radar Systems: Bharat Electronics Limited (BEL) is positioning its Coastal Surveillance Radar Systems (CSRS) across regional littorals, creating unified radar integration compatible with India’s Information Fusion Centre – Indian Ocean Region (IFC-IOR).

  • Sub-Tier Ammunition Off-Take: Sustained naval operational deployments generate steady export requirements for domestic naval ammunition and electronic warfare suites (Solar Industries, Data Patterns).

Strategic Autonomy in Action: Why ASEAN Chooses Multi-Alignment

Smaller Southeast Asian states refuse to be reduced to pawns in a binary US-China confrontation. By welcoming INS Kulish at Ream Naval Base, Cambodia signals that its sovereign ports remain accessible to democratic, non-aligned partners. For India, engaging Cambodia without ideological preconditions demonstrates leadership of the Global South, proving that maritime security can be cooperative rather than coercive.

4. Historical Precedent: The Cold War Port-Call Protocol

The strategic logic behind the docking of INS Kulish at Ream Naval Base mirrors naval diplomacy during the Cold War. In contested regions such as the Mediterranean and the Horn of Africa, rival superpowers frequently attempted to designate third-party ports as exclusive spheres of influence.

The routine dispatch of naval surface combatants for friendly, non-belligerent port calls by independent powers proved vital to preventing unannounced annexation of sovereign waters. By dropping anchor at Ream, INS Kulish reaffirms the foundational maritime law of the sea: international waterways and sovereign ports cannot be converted into closed military lakes.
