Which country is the world's largest archipelagic state?

The story behind the answer

Indonesia is the world's largest archipelagic state. Its territory stretches across Southeast Asia and Oceania between the Indian and Pacific oceans, linking major maritime routes such as the Malacca, Sunda, and Lombok straits.

Indonesia comprises more than 17,000 islands, including Java, Sumatra, Sulawesi, and parts of Borneo and New Guinea. The country is not simply a chain of isolated islands: under the archipelagic-state concept recognized in international law, its surrounding waters help bind the islands into a single national territory.

A major milestone was the 1957 Djuanda Declaration, which asserted Indonesian control over waters between its islands. That principle was later recognized through the United Nations Convention on the Law of the Sea. A common mix-up is confusing the largest archipelago as a physical island group with the largest country made up of islands; the quiz asks for the state, and Indonesia is the standard answer.
