Hi there!
Do you know what "dual nationality" means? It means you are a citizen of two countries instead of just one. For example, if your mommy is from Indonesia and your daddy is from China, you can be a citizen of both Indonesia and China!
Well, sometimes people who are citizens of two countries have problems because the rules of one country don't let them be citizens of another country, or maybe they have to give up one of their nationalities.
But Indonesia and China made a treaty called the "sino-indonesian dual nationality treaty" that says people who are citizens of both countries (Indonesia and China) can keep both of their nationalities! That means they don't have to give up one of their nationalities just because they want to be a citizen of the other country.
This treaty makes it easier for people who have families in both Indonesia and China, or who work or study in both countries, because they can be a citizen of both and don't have to worry about things like visas or work permits as much. And it helps keep families together and communities strong.
So, that's what the sino-indonesian dual nationality treaty is all about - making it easier for people who are citizens of both Indonesia and China to keep both of their nationalities!
