Sihanoukville Infrastructure Development – New Roads, Ports, and Airport in 2025
Sihanoukville Infrastructure Development

Sihanoukville, known as Cambodia's coastal capital, has undergone a massive transformation in recent years.
From a small tourist resort, it has evolved into a key commercial and investment hub, supported by the Cambodian government and investors from China, Japan, and South Korea.
In 2025, the city is entering a new phase of development—construction of new roads, port terminals, and expansion of Ream Airport, which directly impacts property values and the region's investment appeal.
