According to the Chinese text Jiu Tang Shu, Pan Pan was bordered in the south with Langkasuka,[1]: 53 and in the north with Tun Sun near the Kra Isthmus.[3]: 259 Jacq-Hergoualc'h speculates that the border may have been south of Nakhon Si Thammarat, possibly near Songkhla.[1]: 53
After the northern neighbor Tun Sun gained independence from Funan and became Lang-chia or Lang-ya-hsiu in the late 5th century CE, its southern part joined Pan Pan in the 6th century,[3]: 262–263 while the northern territory became Dvaravati.[3]: 268–269
It is speculated to be related to the Patani Kingdom, which occupied the same area many centuries later, and has some differences in culture and language to other Malay regions nearby.
Pan Pan sent tribute to the Liang dynasty and the Chen dynasty of China. in 529, 533, 534, 535 and 571[6] In 616 and 637, Pan Pan sent tribute to the Chinese Tang dynasty.[7]
The kingdom was later conquered by Srivijaya under the leadership of Dharmasetu before 775.[8]
Though rare, archeological discoveries show evidence of a lively economic flowering in the region through international maritime trade.[9]
