In this study, researchers focused on research on border diplomacy by the Indonesian side of Malaysia to accelerate the construction of the International Goods Terminal at the border of Entikong, Sanggau Regency, West Kalimantan, which the Indonesian Ministry of Transportation built to regulate and facilitate the flow of foreign goods in the border region. The approach used by researchers in this study uses a qualitative approach, the location chosen as the research location is adjusted to the area where the International Goods Terminal was built, namely in the Entikong Subdistrict, Sanggau District, considering that in this very strategic border region international economic activities are often carried out but governance and progress in the area are still lagging when compared to neighboring Malaysia. In determining the researcher's informant using a purposive technique, the informants in this study were Sanggau District Head, Entikong District Head, Sanggau Cross-border Post Head, and the Malaysian Consulate. The results of this study found that in the process of accelerating the construction of the International Goods Terminal to expedite international economic flows by increasing clear customs related to the export-import of goods through dry port lines or so-called International Goods Terminals this was done through border diplomacy by the Indonesian side through the Malindo Social Institution. Public policy on cooperation between Sosek Malindo and governments in diplomacy related to affirming the legal status of the construction of the International Goods Terminal is carried out to control the obstacles that arise in the effort to accelerate it.
