Answer:
Buddhism spread across Asia through networks of overland and maritime routes between India, Southeast Asia, Central Asia, and China. The transmission of Buddhism to Central Asia and China corresponded with the development of the silk routes as channels for intercultural exchanges.
Explanation:
Buddhism was spread outside India through the efforts of missionaries, scholars, trade, emigration, and communication networks. Foreign monks who travelled along the silk route between India and China were responsible for the spread of Buddhism at sub-elite levels.
