Differences between countries and regions:

The fundamental difference between countries and regions lies in whether they have sovereignty. Countries have sovereignty, but regions have no sovereignty, so they are not recognized as independent countries by the international community, and the degree of regional autonomy is very high.

Some borders are determined by inter-state treaties or international treaties, which have legal basis and are generally stable; However, some borders have not been recognized by each other, let alone by the international community, thus causing border disputes and becoming the bane of conflicts and wars.
