International treaties play a crucial role in state sovereignty by establishing rules that govern relations between nations. While these agreements can enhance cooperation on issues like trade, environmental protection, and human rights, they also pose challenges to sovereignty as states may need to comply with external regulations. Treaties can impact national laws and policies, requiring nations to balance their domestic interests with international obligations. Consequently, the interplay between sovereignty and treaty commitments raises critical questions about the nature of national autonomy in a globalized world.
