via the SPAFA Journal, 30 August 2021: A paper by Tran Ky Phuong and Nguyen Thi Thu Anh on Chola influence in Cham architecture.
New construction technology and new aesthetic trends are emphasized as the characteristics of Chola influence which have been adapted in Cham religious architecture. The temple architecture and sculptures of Champa thus provide the best information on reflecting the pinnacle of Champa art dating from the 11th and 13th centuries CE. Champa became a center for transportation with its prosperous port-cities/port-polities expressing demand for import-export commodities, especially the trade between South India and South China. The Champa kingdom had thus been one of the main bridges for Chola art to reach Southeast Asian states which was achieved through the commercial perspective and religious art.
