Challenge
Cambodia, sitting at the heart of mainland Southeast Asia, plays a pivotal role in supporting connectivity – an area directly aligned with U.S. national and economic security interests in the Indo-Pacific. Its relationship with the United States has strengthened in recent years, driven by Phnom Penh’s irreplaceable role as a source of regional stability. A landmark Open Skies agreement is poised to unlock new commercial opportunities for the private sectors in both countries, and breakthroughs in trade relations have, as the Office of the U.S. Trade Representative assesses, created “commercially meaningful market access opportunities for the full range of U.S. exports, supporting high-quality American jobs.”
But Cambodia’s evident potential for growth has also been constrained by its aging infrastructure. Its legacy airport, Phnom Penh International, had severely limited capacity, constraining U.S. trade, investment, and market access. Gaps in its air transit systems constrained the growth of trade and foreign investment and created knock-on effects that undermined its domestic economy.
In recent years, Phnom Penh International handled roughly 6 million passengers annually – conspicuously fewer than other leading airports in the region. Cargo constraints have been comparably stark, with Phnom Penh’s processing fewer than 60,000 tons of air freight in 2019. And the lack of direct long-haul flights limited tourism to the capital itself and the popular resort city of Siem Reap – all impeding reliable local and international participation in the aviation sector.
Solution and Impact
DFC seeks to provide a loan of up to $100 million to the Overseas Cambodian Investment Corporation, or OCIC, for the first phase of the Techo International Airport. Located only 12 miles south of Phnom Penh, the new transit hub that replaces its constrained predecessor is poised to lower travel costs to and from the United States, bolster Cambodia’s critical infrastructure, help expand its local economy, and create new levels of regional interconnectivity.
The new airport is expected to handle 15 million passengers per year for Phase 1, accommodate both international and domestic travel, and reduce reliance on regional transit hubs.
It is also poised to increase cargo capacity to 175,000 tons per year – strengthening Cambodia’s trade network while supporting exports from its garments, electronics, and agricultural products industries.
The high-visibility, nationally strategic, prestige project represents the kind of capital-intensive investment in which DFC specializes, particularly with its newly expanded funding and authorities. And OCIC, one of Cambodia’s legacy investment conglomerates wielding local insights and a strong commitment to global standards, represents a prime example of a best-in-class operator with which DFC seeks to partner.
The Techo International Airport project is designed to support Cambodia’s economic growth by improving its connectivity and air capacity as well as closing key gaps in its existing infrastructure. It is indicative of the type of strategic infrastructure projects DFC is well positioned to support in Cambodia and throughout the ASEAN region.
