Imagine you have a group of friends who all share toys. But you want to join them too! This is what Afghanistan is doing - trying to join a group of countries that share things together, called the World Trade Organization (WTO).
When you want to join the group of friends, you have to follow some rules that everyone agrees upon. For example, you have to share your toys with everyone and not take anyone else's toys without asking. In the same way, when you want to join the WTO, you have to agree to follow their rules for trade (buying and selling things between countries).
Afghanistan has been trying to join the WTO for a while now, and they have finally made progress in their application. This means they are getting closer to becoming a member of the group of countries that share things together.
If they become a member, it will be easier for Afghanistan to trade things with other countries because they will have fewer restrictions and lower taxes on their products. This will help their economy grow and create more jobs for people in Afghanistan.
So, just like how you have to follow the rules to join your group of friends, Afghanistan has to follow the rules of the World Trade Organization to become a member.
