All Under Heaven: does it mean China?

In the Chinese view, the center of the world is the Chinese emperor’s court, surrounded in turn by concentric circles: senior officials, junior officials, ordinary citizens, and finally vassal kingdoms and “barbarians”. Classical Chinese political thought held that the Chinese emperor ruled the entire world, and all known foreign kingdoms were merely his vassals. In classical Chinese philosophy, “All Under Heaven” is synonymous with civilization and order as understood by the Chinese, and denotes the Chinese people’s place in the world.

Today, the term 天下 is used in China to mean “the whole world”, whereas in Russia it refers specifically to China. (source: Wikipedia/All Under Heaven)

Meanwhile, Russian editions of the Vedas use the term “Podnebesye” (“Under Heaven”) to denote the world as a whole, rather than an individual country.
