Bilateral aid refers to the provision of financial, technical, or other forms of assistance from one country to another. It involves the direct transfer of resources, expertise, or knowledge between two countries, typically through government-to-government channels. Bilateral aid can take various forms, including grants, loans, technical assistance, capacity building, and humanitarian assistance. It is often used by donor countries to support development projects, promote economic growth, address poverty, improve governance, or respond to humanitarian crises in recipient countries.
