Earliest deciphered writing in Asian zone: Indus Valley writing, undeciphered, predates this to circa 2600 BCE.

The earliest known writing system in Asia is typically considered to be the Oracle Bone Script from ancient China. This script was used during the Shang Dynasty around 1200 BCE, but evidence suggests it may have developed as early as 1250 BCE or earlier. Oracle Bone Script was primarily used for divination purposes and was carved on animal bones or turtle shells. These artifacts, known as oracle bones, were used to communicate with ancestors and gods to ask about weather, crop planting, the fortune of the kingdom, and other issues of state and religious importance. The script is a direct precursor to modern Chinese characters, making it not only one of the oldest forms of writing in Asia but also a foundational element of one of the world’s continuously used writing systems.
