The Techo Global Air Terminal is Cambodia’s newest and largest airport project, slated to open in mid-2025. Developed by Cambodia Airport Investment Co., Ltd (CAIC), this ambitious project marks a significant step forward in Cambodia’s infrastructure development. The airport is located 19 kilometers from Phnom Penh. It is in Kandal Stung District, Kandal Province. It spans 2,700 hectares and is designed to meet global standards.
As one of the most advanced airport projects in the region, it will transform Cambodia’s aviation sector. It will also bolster its capacity for international tourism and business travel. Techo Global Air Terminal is the freshest and biggest air terminal project in Cambodia. It is planned to open in mid-2025. This was affirmed by the development organization Cambodia Air Terminal Speculation Co., Ltd (CAIC) before.

The Techo Global Air terminal opened its building site in mid-2020 on an area of 2,700 hectares. It is situated in Kandal Stung Locale, Kandal Territory. It is located around 19 kilometers from Phnom Penh. The new air terminal is in the F4 classification, which is being created in three stages. The primary stage will cost a sum of $ 1.5 billion, excluding the air terminal region.
The main stage is set to launch in mid-2025. At that point, Techo Worldwide Air Terminal will receive 13 million travelers each year. The subsequent stage will end in 2030. It can get 30 million sightseers each year. The year and third stage will end in 2050 and can get 50 million sightseers each year.
The first phase is set to launch in 2025. Techo Global Air Terminal will be capable of handling 13 million passengers annually. By the third phase in 2050, the airport will accommodate up to 50 million tourists each year. Read more here.

This massive project will not only enhance Cambodia’s connectivity but also boost its economic growth by supporting tourism and trade. Stay updated on the progress of this remarkable project by visiting the second project for more information and developments.

Reasons for building Techo International Airport
This is a significant infrastructure project for Cambodia. Several strategic reasons drive the decision. It concerns building the new Techo International Airport, officially called the New Phnom Penh International Airport. Eventually, the current one will be closed.
1. Limited Capacity for Future Growth
The existing Phnom Penh International Airport (PNH), located just 10 kilometers west of the city center, is severely constrained.
- Space Restrictions: It is hemmed in by urban development, making physical expansion extremely difficult and expensive. There’s no room to add a second runway.
- Single Runway: This limits the number of aircraft movements (takeoffs and landings) per hour. It creates a bottleneck, especially during peak times.
- Terminal Size: The current terminal, even with upgrades, has a limited capacity for passengers. Over the past two decades, Cambodia has seen a massive increase in tourist arrivals. Business travel has also surged. This growth is expected to continue.
The government anticipates that the current airport will not be able to handle the projected future passenger traffic. They estimate that it will reach 13 million+ per year in the coming decade.
2. Strategic Economic Development and Vision
The new airport is a cornerstone of Cambodia’s long-term national development strategy.

- A Hub for the Region: The government envisions Cambodia as a more significant aviation and logistics hub. Phnom Penh, in particular, is central to this vision for Southeast Asia. A large, modern airport is critical to attracting more international airlines, direct long-haul flights, and increased cargo traffic.
- Boosting Tourism and Investment: A world-class airport is the first impression for tourists and investors. The Techo International Airport is designed to be a modern gateway. It signals Cambodia’s ambition and economic progress. This makes it more attractive for high-value tourism and foreign direct investment.
- Stimulating Regional Development: The location of the new airport (approx. 30-40 km south of central Phnom Penh) is strategic. It aims to spur massive economic development in that southern corridor. This includes new industrial zones, logistics centers, satellite cities, and tourism facilities. This helps decongest the capital and distribute economic activity.
3. Addressing Safety and Urban Encroachment
The current airport’s location in a densely populated area presents challenges:
- Safety Zones: Aviation safety regulations require clear zones at the end of runways. Urban sprawl has encroached on these areas. This creates potential safety risks. It limits the types of aircraft that can use the airport to their full capacity.
- Noise Pollution: Aircraft taking off and landing create significant noise. This noise is a nuisance for residents in a densely populated capital city. It also limits operations, especially at night.
- Road Congestion: The roads leading to the current airport are often heavily congested, making access difficult for travelers.
The new airport site has ample space for proper safety buffers. It is also far enough from the urban core. This minimizes noise issues for the majority of the population.
4. Massive Scale and Modern Facilities
The Techo International Airport is being built on a completely different scale:
- 4F-Class Airport: This is the highest ICAO classification. It will be capable of handling the world’s largest aircraft. These include the fully loaded Airbus A380 and Boeing 747-8.
- Multiple Runways: The master plan includes three runways. The first one is complete. A massive terminal is capable of handling 13 million passengers in its first phase. Future expansions are planned to eventually handle 50-60 million passengers per year.
- Cargo Capacity: It is designed with a major focus on cargo. This focus is vital for exporting Cambodian goods, such as garments and agricultural products. It also helps in becoming a regional logistics player.
Why New Airport Instead of Expanding the Old One?
Simply put, expanding the old airport was not a feasible long-term solution. The land constraints and cost of acquiring urban land would have been prohibitively expensive and logistically nightmarish. Building a new, larger airport on a “greenfield” site from scratch was deemed a more efficient and future-proof investment.
The Role of China
It’s important to note the project’s funding, as it explains the “how” behind this ambitious plan:
- The project is being developed by the Cambodia Airport Investment Co., Ltd. (CAIC). It is a joint venture between the Cambodian government through the State Secretariat of Civil Aviation. Additionally, it involves a Chinese state-owned enterprise, the Overseas Cambodia Investment Corporation (OCIC). However, the vast majority of the funding (over $1 billion) comes from Chinese banks in the form of loans.
- This is a hallmark of China’s Belt and Road Initiative (BRI), which finances large-scale infrastructure projects around the world. This gives Cambodia the capital to build a project it couldn’t finance alone. At the same time, China gains strategic influence and secures contracts for its companies.
Conclusion
In summary, the Cambodian government’s decision to build the Techo International Airport and eventually close the current one is a strategic move driven by:
- Necessity: The old airport is maxed out and cannot be expanded.
- Ambition: To create a modern hub that boosts tourism, trade, and Cambodia’s status in the region.
- Practicality: To solve urban safety, noise, and congestion issues.
- Opportunity: To spur massive economic development in a new area south of the capital.
It is a quintessential “nation-building” project aimed squarely at securing Cambodia’s economic future.
