Final answer:
The North-South Joint Declaration of 1972 contains three principles aimed at reunification: Independence, without foreign interference; Peace, without force; and National unity, emphasizing a shared identity.
Step-by-step explanation:
The North-South Joint Declaration of 1972 is a significant event in Korean history, focusing on the principles of reunification between North and South Korea. Unfortunately, it seems there has been some confusion in the question asked, as the Declaration on Liberated Europe discusses European affairs post-World War II rather than the Korean context.
Moreover, the principles of reunification you may be asking about are not found in the details provided about Europe, China's policies, or the Vietnam War. Those documents and events are not directly related to the North-South Joint Declaration of 1972.
To clarify, the three principles of the 1972 North-South Joint Declaration are:
- Independence - reunification should be achieved independently without the interference of foreign powers.
- Peace - reunification should be achieved peacefully without the use of force against each other.
- National unity - recognizing that North and South Koreans are of the same nation and striving for national unity.
The intention of these principles was to set a foundation for future dialogues and potential reunification, emphasizing autonomy, a peaceful approach, and a sense of shared national identity between the two Koreas.
