[1] Dated 400–100 BCE,[2] Khao Sam Kaeo served as an extremely important port, as well as a crossroads for Asian connection and interaction, as it sat between the cultural regions of the South China Sea and the Bay of Bengal.

[3] There is evidence that material had come from the South China Sea, the Philippines, and Taiwan—all part of the maritime silk road of the time—proving the important technological and cultural connections between the site and these locations.

[3] When reviewing the material culture found at Khao Sam Kaeo, the transfer of ideas and trans-Asian connection becomes abundantly clear, especially when looking at ceramics, stone adzes, pendants, and jewelry.

[3] Data and research also point to the idea that foreign craftsmen stayed for long periods of time at Khao Sam Kaeo.

Near Wall 8 located along the eastern plateau of Hill 3, there contained occupational layers associated with iron-forging and then eventually the production of stone ornaments.

[1] Khao Sam Kaeo served as a major cross-cultural port and center for trade of goods, materials, and culture.

Analysis of goods at the site reveals that trade was not sporadic, leading to the adoption of foreign technology or ideas, but a socially significant, multicultural long term interaction.

[4] Copper metallurgical typologies found at the site reflect Vietnamese, Southern Asian, and Han technologies, revealing the importance of Khao Sam Kaeo as a center of trade triangulation.

[7] This suggests that the sources from which the beads were made came from different places, aiding in the idea of foreign practice at Khao Sam Kaeo, as well as high levels of trade.

The connection and similarities between the glass piece composition highlights the importance of Khao Sam Kaeo as not only a crossroads for economics, but also art and culture.

This typological form has been found throughout the Indian subcontinent, most prominently dating between the third and second centuries BCE, and indicate a transmission of ideas that made their way to Southeast Asia.

Evidence reveals that metalworkers at Khao Sam Kaeo were producing high-tin bronze ingots for export as well as for production tools.

[8] Khao Sam Kaeo is a site that has provided a significant amount of evidence to show the development of methods and ideas related to glasswork.

[10] Based on evidence found at the site, it appears that most of the glassworking techniques used at Khao Sam Kaeo were brought in from outside sources, as opposed to being established and refined locally.

[10] And, as stated previously, there is clear and abundant evidence that not only the glassworking techniques were brought in from outside sources, but that the materials used in the composition of the glass were also imported.

[7] Based on compositional analyses done on the glass at Khao Sam Kaeo and other sites located throughout Southeast Asia, it is suggested that there was at least some kind of exchange network of glass ornaments and raw materials between Khao Sam Kaeo and sites in Vietnam such as Giong Ca Vo and the Tabon Caves in Palawan.
