In Orwell's 1984, the planet has been divided into 3 superstates. What are their names?

In Orwell’s 1984, the planet has been divided into three superstates: Oceania, Eurasia and Eastasia. These enormous totalitarian blocs dominate the novel’s political geography and remain in a state of perpetual war.

Oceania includes the Americas, the Atlantic islands including the British Isles, Australasia and southern Africa. Eurasia encompasses the northern European and Asian landmass, while Eastasia consists primarily of China and countries to its south, along with the Japanese islands and contested territories.

The alliances between the superstates can change suddenly. Oceania may be allied with Eurasia and fighting Eastasia, then reverse those relationships. When that happens, the Party rewrites newspapers and historical records so citizens believe the new alignment has always existed.

The stored answer contains a spelling error: “Oceana” should be “Oceania.” The other two names, Eurasia and Eastasia, are correct.
