Okay kiddo, imagine you have a toy that you really love and you want to trade it with your friend's toy. But what if your friend asks for something that is not fair and equal in exchange for your toy? That's where trade justice comes in.
Trade justice is making sure that when countries trade with each other, they do it fairly and equally. Just like with toys, countries need to make sure they trade valuable things for something valuable in return. That way, everyone benefits and is happy.
But sometimes, big and powerful countries take advantage of smaller and weaker countries in trade deals. They might ask for unfair things or pay very little for valuable resources. This is not fair and can hurt the smaller countries' economies and people.
So, some people believe in trade justice to create fair and equal trading rules between countries. They want to make sure that everyone benefits and that no one is taken advantage of. Just like how you trade toys with your friend, countries should trade fairly too!
