The practical purpose of this study is to advocate for the opening of formal access to borders (between countries) to areas isolated from political, social, and economic accessibility. So that policies can be formulated that support regional development under the characteristics possessed by Entikong both regionally, nationally, and internationally. Some entikong border areas still have access to the sub-district city, which is still experiencing difficulties. So socio-political and economic access is still limited. This research uses a qualitative approach to case studies. Field data were obtained through interviews and observations. The results of this study found that the existence of social interaction, local market (economic) interaction and kinship between communities in the regions in Malaysia and communities in Indonesia positively impacted local economic development. Long-standing residents' interactions with Malaysians have formed social and economic networks in local communities. However, it requires a political process to accelerate the formal open trade access policy at the Entikong border
