What motivated the movement of people who spread ideas into Korea and Southeast Asia?

There were several motivations for the movement of people who spread ideas into Korea and Southeast Asia. One of the primary motivations was trade. Merchants and traders who sailed to these regions brought with them ideas and beliefs from their own cultures and religions. Additionally, the spread of ideas was often linked to the spread of political power. As different empires and kingdoms expanded their influence, they would often bring their own beliefs and cultural practices with them.
