Scholarship and institution-building
Kao Kim Hourn studied in the United States, earning degrees at Baylor University, Ohio University and the University of Hawaii. After returning to Cambodia, he led policy research and created the University of Cambodia in 2003.
His academic and think-tank work developed alongside Cambodia’s reconstruction and deeper participation in regional institutions. He served as the university’s president until October 2022.
Cambodia’s ASEAN diplomat
Kao held senior positions in Cambodia’s foreign ministry and government. He led the country’s ASEAN senior-official work and represented Cambodia on the high-level task force that drafted the ASEAN Charter.
He later served as secretary of state for foreign affairs and as minister delegate attached to the prime minister. These roles placed him at the intersection of Cambodian policy and ASEAN negotiations for more than two decades.
The 15th secretary-general
Kao began his five-year term in January 2023. He organised his priorities around six themes—peace, prosperity, planet, people, partnerships and potentials—while supporting member states’ work on the post-2025 ASEAN agenda.
The secretary-general facilitates and monitors decisions but does not replace the authority of ASEAN governments. Kao’s term therefore illustrates both the growing workload of the Secretariat and the limits built into ASEAN’s intergovernmental design.
