Cambodia has taken a major step in aviation and tourism with the grand opening of the Techo International Airport, a state-of-the-art gateway positioned about 20 kilometers south of Phnom Penh across Kandal and Takeo provinces. Costing between $1.5 and $2 billion, the new facility takes over from Phnom Penh International Airport, which is now reserved for military and special operations.
Prime Minister Hun Manet praised the milestone as “a major step for Cambodia’s aviation and economy.” The airport was built through cooperation between the Cambodian government and the Overseas Cambodian Investment Corporation, with construction carried out by China Construction Third Engineering Bureau Group.
Architecturally, the terminal sets a new benchmark for the region. Created by Foster + Partners, it features a dramatic roof canopy of interwoven steel, supported by columns shaped like trees. A semi-transparent screen filters daylight across the interior, paying homage to Cambodia’s cultural heritage while providing travelers with a bright, welcoming atmosphere. Adding to its innovation, the site is powered in part by an extensive solar energy farm, strengthening the country’s commitment to sustainable development.
The airport became fully operational on September 9, 2025, following months of test flights and inspections. The former Phnom Penh International Airport officially closed for commercial flights the evening before the launch.
Tourism in Cambodia is rapidly rebounding, with international visitor arrivals reaching 6.7 million in 2024, representing a 23 percent increase from the previous year. Techo International Airport is expected to handle 13 million passengers annually in its first phase, with ambitious plans to expand capacity to 30 million by 2030 and 50 million by 2050.
The airport is more than just a transportation hub; it represents Cambodia’s ambition of combining cultural identity, modern infrastructure, and environmental responsibility to ensure long-term progress.
