Answer:
its type of government
Explanation:
The characteristic of a nation that has the most significant impact on citizenship participation in governments throughout Southern and Eastern Asia is "its type of government"
This is evident in the fact that there are different forms of government in these regions that limit or improve the participation of citizens in the governments.
For example, India, Nepal, and Pakistan make use of federal republics, thereby there is an increase in the participation of the citizens in their government. However, places like Bhutan use constitutional monarchy, and North Korea uses absolute monarchy which greatly limits the participation of their citizens in their government.
