The agreement seeks to facilitate sharing experiences in development and aims to use each nation as a gateway to larger regional markets, specifically the ASEAN and African markets. Potential areas for future investment include mining, telecommunications, infrastructure, and agriculture. Following this, Vietnamese officials conducted missions to Portugal and Burundi to further strengthen bilateral ties.
