ASEAN national authorities have also been traditionally reluctant to share or cede sovereignty to authorities from other ASEAN members (although ASEAN trade ministries routinely make cross-border visits to conduct on-site inspections in anti-dumping investigations). Unlike the EU or NAFTA, joint teams to ensure compliance and investigate non-compliance have not been widely used. Instead, ASEAN national authorities must rely on the review and analysis of other ASEAN national authorities to determine if AFTA measures such as rule of origin are being followed. Disagreements may result between the national authorities. Again, the ASEAN Secretariat may help mediate a dispute but has no legal authority to resolve it.
