The Eurasian Economic Union (EAEU) is like an team for countries that want to work together to make trade easier. It's kind of like a club, but it helps countries buy and sell things from each other. The members of the EAEU are Russia, Kazakhstan, Belarus, Armenia, and Kyrgyzstan. These countries have all agreed to share certain rules and laws to help them work together and trade more easily with each other. They will be able to use the same currency, and make sure that goods going across borders are handled in the same ways. This means businesses in one country will be able to buy and sell things more easily in another country, which should help everyone make more money.
