The G20 is a meeting held every year but it isn’t a meeting that anyone can attend. It is an exclusive club which means that you have to get an invite. You can also have exclusive clubs for other things to and it could even be just like a birthday party.
The G20 is attended by 19 of the most powerful countries and a representative from the European Union. They can’t have too many people at the meeting as they would have a lot of trouble deciding on something.
Some of the issues brought up at the meeting are trade, jobs, energy, inequality and more. They hold a meeting each year because it is hard to agree on anything and there is often arguments about decisions that are made. This years meeting is being held in Brisbane but we know they’re not going to solve all of the worlds problems.
