Wastren Asie, Wast Asie, Soothwast Asie or Soothwastren Asie are terms that describe the wastmaist portion o Asie. The terms are pairtly coterminous wi the Middle East, which describes a geographical position in relation tae Wastren Europe rather than its location athin Asie. Due tae this perceivit Eurocentrism, internaitional organizations such as the Unitit Naitions, hae replacit Middle East an Near East wi Wastren Asie. This region an Europe are collectively referred tae as Wastren Eurasie.
The warld's earliest ceevilizations developit in Wastren Asie. For maist o the last three millennia, the region haes been unitit under one or two powerful states; each one succeeding the last, and at times, eastern and western based polities.
