扶南
Although most of the Chinese recordings on Chenla, including that of Chenla conquering Funan ("derived from very weak sources"), have been contested since the 1970s as they are generally based on single remarks in the Chinese annals, the History of the Chinese Sui dynasty contains entries of a state called Chenla, a vassal of the Kingdom of Funan, which had sent an embassy to China in 616 or 617, yet under its ruler, Citrasena Mahendravarman, conquered Funan after Chenla had gained independence.
