When people think of the Khmer Empire, they often picture Angkor Wat, monumental temples and powerful kings. Yet behind these achievements stood an equally impressive economic system. From the empire’s foundation in 802 CE until the 15th century, Khmer prosperity was supported by productive agriculture, skilled water management, busy local markets and extensive international trade.
Rice formed the foundation of the economy. Most Khmer people were farmers who cultivated land near rivers, lakes and irrigated plains. Around Angkor, canals, embankments and enormous reservoirs known as barays helped communities manage water across changing seasons. These systems supported agriculture, settlements and transport, although scholars continue to debate exactly how much of the network was designed specifically for irrigation.
The Tonlé Sap and Cambodia’s many rivers were just as important. Fishing supplied much of the population’s protein, while fish could be preserved as prahok for later consumption or exchange. Families also raised cattle, pigs and poultry around their stilted homes. Village orchards produced coconuts, vegetables, tropical fruits, palm sugar and palm-based drinks. Together, rice and fish sustained one of the premodern world’s largest urban regions.
Angkor was not an isolated inland capital. Its canals, roads and river routes connected farms and forest communities with administrative centres and, eventually, maritime ports. Products collected in Cambodia’s forests were especially valuable overseas. Chinese records mention goods such as beeswax, aromatic woods, kingfisher feathers, elephant tusks, rhinoceros horn, cardamom, resins and other rare natural materials. Some of these goods were valued as medicines, perfumes, ceremonial materials or symbols of prestige.
In return, Khmer rulers and wealthy families sought imported luxury products. Trade and diplomatic exchanges with China brought fine ceramics, lacquerware, silk, metals, mercury and cinnabar. Archaeologists have discovered imported Chinese ceramics and glass at Angkor, offering physical evidence that the Khmer elite participated in wider Asian commercial networks. Some imported objects may have arrived as merchandise, while others were probably diplomatic gifts. Research on Chinese ceramics found at Angkor confirms connections stretching back across several Chinese dynasties.
China was an important partner, but it was not the only one. Khmer merchants and officials were connected to the Indian Ocean trading world through ports and intermediaries. Tamil merchants, maritime Southeast Asian powers such as Srivijaya and Java, and regional neighbours including Champa and Siam formed part of this network. The empire’s participation in trade was therefore both continental and maritime: goods travelled by road, canal and river before joining sea routes linking Southeast Asia with China and India.
The domestic marketplace looked very different from elite international trade. One of the richest descriptions comes from Zhou Daguan, a Chinese diplomat who lived at Angkor in 1296–1297. He described open markets without permanent shops, tables or chairs. Vendors spread woven mats on the ground and displayed their goods, sometimes beneath simple shelters. Officials collected rent or a market fee according to the space each trader occupied.
Most strikingly, Zhou reported that women managed local commerce. They sold agricultural produce, household necessities and other everyday goods, making them central to Angkor’s economic life. While kings and foreign envoys dominated official records, women handled many of the transactions that kept families and neighbourhoods functioning. Their role demonstrates that the Khmer economy was not sustained only by royal institutions or great construction projects. It also depended on practical knowledge, negotiation and countless daily exchanges.
Calling this economy purely a barter system would be an oversimplification. Exchange operated at several levels. Zhou’s account indicates that rice and grain could be used for smaller purchases, cloth for more valuable transactions, and gold or silver for expensive goods. Coins appear not to have circulated as widely as they did in some neighbouring societies, but precious metals still served as measures and stores of value. The economy therefore combined barter, commodity payments, taxation, tribute and elite-level monetary exchange.
The Khmer Empire’s commercial strength came from its ability to connect different worlds: farmers with cities, forests with foreign courts, inland waterways with maritime routes, and village markets with royal diplomacy. The temples remain its most visible legacy, but they were made possible by something less monumental and more human, a productive countryside, organised transport systems and generations of traders, particularly women, who kept goods moving every day. Angkor was not simply a city of stone. It was the centre of a living, connected and remarkably sophisticated economy.
