 As some of Rajendra Chola III's inscriptions are found in places under Kopperunchinga's control, we may assume that these two rulers were acting as allies both against the Kakatiya dynasty and against the Pandyas to the south, who historically had been enemies to both Pallavas and Cholas.Kopperunchinga's relationship with the Pandya king Jatavarman Sundara Pandyan, though by no means cordial, somehow never led to outright war.This is because Kopperunchinga at the time was engaged in prolonged wars against other rulers of Karnataka and the Telugu chiefs, and his repeated successes against them indirectly helped the Pandya king.
