The Convention on the Elimination of All Forms of Racial Discrimination is like a big book of rules that countries all over the world agreed to follow. It says that people should be treated with kindness and fairness, no matter what color their skin is or where they come from.
For example, imagine if you had a friend with brown skin. If someone didn't want to play with your friend or be their friend just because of the color of their skin, that wouldn't be fair or kind. The Convention says that countries should make sure that people are not treated unfairly just because of their race or ethnicity.
The Convention also tells countries to make laws and policies that protect people from racial discrimination. This means that countries cannot allow things like racism or hate speech.
Overall, the Convention on the Elimination of All Forms of Racial Discrimination is an important way to make sure that everyone is treated with respect and kindness, no matter what they look like or where they come from.
