Eastern philosophy
Many societies have considered philosophical questions and built philosophical traditions based upon each other's works. Eastern and Middle Eastern philosophical traditions have influenced Western philosophers. Russian (which to many people still counts as Western), Jewish, Islamic and recently Latin American philosophical traditions have contributed to, or been influenced by, Western philosophy, yet each has retained a distinctive identity.
The differences between traditions are often based on their favored historical philosophers, and varying stress on ideas, procedural styles, or written language. The subject matter and dialogues of each can be studied using methods derived from the others, and there are significant commonalities and exchanges between them.
Eastern philosophy refers to the broad traditions that originated or were popular in India, Persia, China, Japan, and to an extent, the Middle East (which overlaps with Western philosophy due to the spread of the Abrahamic religions and the intellectual give and take between these societies and Europe.)
