Saudi foreign assistance is when the country of Saudi Arabia gives money or help to other countries that need it.
It's like when you have a friend who needs help with their homework and you offer to help them so they can do better in school. Saudi Arabia does something like that, but on a much bigger scale - they help other countries with things like education, healthcare, and disaster relief.
When a country is going through a hard time, like when there is a flood or an earthquake, Saudi Arabia can provide assistance to help people who are affected. They might send supplies like food, water, or blankets, or they might send people with special skills, like doctors or engineers, to help in the relief effort.
Saudi Arabia can also help with development projects, like building schools or hospitals, to make life better for people in other countries.
So, in summary, Saudi foreign assistance is when Saudi Arabia helps other countries by giving them money, supplies, or expertise to improve conditions and help people who are in need.
