What are the differences between national integration and national unity?

National integration refers to the process of uniting different groups within a nation to create a cohesive society, while national unity refers to the state of being united as one nation, despite differences. National integration focuses on addressing social, cultural, and economic divisions, whereas national unity emphasizes the collective identity and shared values of a nation. Ultimately, national integration aims to build mutual understanding and respect among diverse groups, leading to national unity.
