Between 1079 and 1088, Chinese records show that Srivijaya sent ambassadors from Jambi and Palembang. In 1079 in particular, an ambassador from Jambi and Palembang each visited China. Jambi sent two more ambassadors to China in 1082 and 1088. This suggests that the centre of Srivijaya frequently shifted between the two major cities during that period. The Chola invasion of Srivijaya and as well as changing trade route weakened Palembang, allowing Jambi to take the leadership of Srivijaya from the 11th century on.
