• On April 5, 2025, Cambodia's Prime Minister Hun Manet inaugurated the Ream Naval Base following renovations funded by China.
  • The event comes after growing concerns raised by the United States regarding China's strategic involvement in the base.
  • It is located along Cambodia's southern coastline in the Gulf of Thailand.
  • Cambodia's leadership has repeatedly denied that the base is being built for exclusive Chinese use, emphasizing its openness to joint exercises and international cooperation.

BACKGROUND & STRATEGIC IMPORTANCE

  • The Ream Naval Base, situated near the disputed South China Sea, has been a point of contention due to its potential to provide China with a key strategic position in the region.
  • The South China Sea is a critical waterway with overlapping territorial claims by multiple countries, including China, Vietnam, and the Philippines.

CHINA’S ROLE IN RENOVATION

  • Since 2022, China has been contributing to the revamping of the base, which was originally partly funded by the United States.
  • The base now features a 363-meter pier and facilities designed for hosting military operations, including joint military exercises.

US CONCERNS

  • The United States has expressed concerns that the base could be used by the Chinese navy, potentially expanding China's military footprint in Southeast Asia.
  • These concerns stem from a 2019 report suggesting a secret agreement for China to use the base for warships.
  • further intensifying suspicions about the region's military balance.
THE GEOPOLITICAL CONTEXT Cambodia’s growing alliance with China has become a significant part of its foreign policy in recent years. As a longstanding ally of China in Southeast Asia, Cambodia has:
  • Bilateral Investments:
    • China has invested billions in Cambodian infrastructure under the Belt and Road Initiative (BRI), strengthening economic ties between the two nations.
    • This has led to increased Chinese influence over Phnom Penh, especially as Washington's relationship with Cambodia has become more strained in recent years.
  • US-Cambodia Relations:
    • The US-Cambodia relationship has declined in recent years, particularly after a 2019 Wall Street Journal report that raised concerns over a secret deal that would allow China to station warships at the Ream base.
    • This has led to further US military visits to Cambodia in recent years, including the docking of a US warship at Sihanoukville in December 2023.
  • Japan-Cambodia Cooperation:
    • In contrast, Japan has also strengthened its ties with Cambodia, and recently, a Japanese warship became the first to dock at the Ream Naval Base.
    • It is signaling Japan's strategic interest in the region.
CAMBODIA’S DEFENCE MODERNISATION The Ream Naval Base is part of Cambodia's broader defense modernization efforts, which include:
  • Warship Donations from China:
    • China has pledged to donate two warships to Cambodia boosting the country’s naval defense capabilities.
  • Strengthened Defense Relations with Other Nations:
    • Cambodia has also expanded defense ties with other powers like the United States and Japan to balance its relations with China and ensure regional stability.

IMPLICATIONS FOR INDIA & THE INDO PACIFIC

  • Concerns for India:
    • The expansion of the Ream Naval Base has significant consequences for India, particularly in relation to its maritime interests in the Indo-Pacific region.
    • The base’s location near vital sea lanes frequently used by the Indian Navy raises alarms about the potential for strategic encirclement.
    • If the People’s Liberation Army Navy (PLAN) establishes a presence there, it could hinder India’s operations in the region, especially during regional conflicts.
  • Impact on Maritime Security:
    • An increased Chinese presence at Ream would enhance its naval capabilities in Southeast Asia, potentially challenging India’s interests in both the Bay of Bengal and the Indian Ocean Region.
    • As a result, India may need to bolster its naval presence in the Andaman and Nicobar Islands to more effectively monitor and counter Chinese activities in these key waters.
