The Sa Huynh culture in what is now central and southern Vietnam had extensive trade with the Philippine archipelago during its height between 1000 BCE and 200 CE.

Sa Huynh beads were made from glass, carnelian, agate, olivine, zircon, gold and garnet; most of these materials were not local to the region, and were most likely imported. Han Dynasty-style bronze mirrors were also found in Sa Huynh sites. Conversely, Sa Huynh produced ear ornaments have been found in archaeological sites in Central Thailand, Taiwan (Orchid Island), and in the Philippines, in the Palawan Tabon Caves. in The Kalanay Cave is a small cave located on the island of Masbate in central Philippines. The cave is located specifically at the northwest coast of the island within the municipality of Aroroy.

The site is one of the "Sa Huynh-Kalanay" pottery complex which is shares similarities with Vietnam. The type of pottery found in the site were dated 400BCE-1500 CE.
