Zabag is uvarnadvipa

Zabag (Chinese: Sanfotsi; Sanskrit: Suvarnadvipa, Javaka; Arabic: Zabaj) is thought to have been an ancient kingdom located south of China somewhere in Southeast Asia, between the Chenla Kingdom (now Cambodia) and Java. The established studies by several historians associated this kingdom with Srivijaya and pointed its location somewhere in Sumatra, Java orMalay Peninsula.[1] However its exact location is still the subject of debate among scholars. Other possible locations such as northern Borneo and Philippines are also suggested.[2]
