Expanding international trade characterizes this period in Southeast Asia: Indonesian outriggers travel to the East African coast; Indian ceramics and glass beads are found in Bali and on the mainland; Chinese mirrors and Roman coins have been excavated in Cambodia; and horses from the Kushans in northwest India are imported. By the sixth century A.D., Indian influence on the mainland is significant—prosperous kingdoms in Thailand adopt Indian political, cosmological, and religious practices, and Sanskrit inscriptions are found in eastern Kalimantan and western Java.
