Multinational agreements can significantly impact domestic law by establishing frameworks that countries must adhere to in areas such as trade, environmental policy, and human rights. These agreements often require nations to amend their laws to comply with international standards, resulting in legal harmonization. For instance, countries may need to enact legislation that aligns with trade agreements to benefit from reciprocal trade advantages. However, compliance can also lead to tensions between national sovereignty and international obligations, complicating the legislative process.
