Farther India
Old term for Southeast Asia
From Wikipedia, the free encyclopedia

Farther India, Further India, or Ultraindia, is an old term, now rarely used, for Southeast Asia, seen in colonial days from Europe as the part of the Far East beyond the Indian subcontinent, but south of China.[1][2]: 190
It refers to Indochina (Cambodia, Laos, Myanmar (aka Burma), Thailand (former Siam), Vietnam, and West Malaysia) and the Malay states (Brunei, East Malaysia, Indonesia, and Singapore), but usually not including the Philippines or Timor-Leste; these neighbouring predominantly Malay states usually belong to the wider East Indies (which includes all of the above as well as the Indian subcontinent).
