Establishment of Trade Relations between the Kingdom of Ayutthaya and the Dutch East India Company (1630s)

Timeline

1. 1631–1633City of Ayutthaya · SiamThe Dutch East India Company dispatched a diplomatic envoy to the capital of the Kingdom of Ayutthaya, presenting letters and gifts to King Prasat Thong in seeking to establish formal trade relations. The two sides held preliminary consultations on Dutch trading privileges in Siam, tariff treatment, and the location of a trading post, with the Dutch using their shared interest in countering their common enemy Portugal as negotiating leverage.
2. 1634–1635Dutch Trading Post, City of Ayutthaya · SiamIn 1634, the Dutch East India Company was permitted to establish a fixed trading post (factorij) within the city of Ayutthaya, marking the formal establishment of bilateral trade relations. The post was located in the city's foreign merchant quarter, responsible for purchasing Siamese specialties such as deerskins, tin ore, and sappanwood, and exporting textiles, spices, and silver dollars to the local market, forming a mutually beneficial trade pattern.
3. 1636–1640City of Ayutthaya · SiamThe Dutch trading post's trade in Ayutthaya grew increasingly stable; deerskins became the largest export commodity, shipped in large quantities to the Japanese market in exchange for silver, while tin ore was transported to Europe via the Strait of Malacca. The Siamese kingdom benefited from trade taxes and European industrial goods, and the VOC used this foothold to penetrate deep into the Southeast Asian mainland; Dutch–Siamese trade relations laid the foundation for decades of subsequent cooperation.
