Traditionally, ASEAN national authorities have also been reluctant to share or cede sovereignty to the authorities of other ASEAN members (although ASEAN trade ministries regularly conduct cross-border visits to carry out on-site inspections as part of anti-dumping investigations). Unlike the EU or NAFTA, joint enforcement and enforcement teams are not widespread. Instead, ASEAN national authorities must rely on the verification and analysis of other ASEAN national authorities to determine whether AFTA measures, such as the rule of origin, are being complied with. Discrepancies may arise between national authorities. Again, the ASEAN secretariat can help resolve a dispute, but does not have the legal authority to resolve it. The Framework Agreement was signed by eleven Heads of Government on 4 November 2002 in Phnom Penh, Cambodia. : Hassanal Bolkiah (Sultan of Brunei Darussalam), Hun Sen (Prime Minister of Cambodia), Megawati Soekarnoputri (President of Indonesia), Bounnhang Vorachith (Prime Minister of Laos), Mahathir ben Mohamad (Prime Minister of Malaysia), Than Shwe (Prime Minister of Burma), Gloria Macapagal-Arroyo (President of the Philippines), Goh Chok Tong (Prime Minister of Singapore), Thaksin Shinawatra (Prime Minister of Thailand), Phan Văn Khải (Prime Minister of Vietnam), Zhu Rongji (P) Minister of Foreign Affairs of the State Council of the People`s Republic of China).   The ASEAN-China Free Trade Area (ACFTA) is a free trade area between the ten member states of the Association of Southeast Asian Nations (ASEAN) and the People`s Republic of China. Regional trade agreements are multiplying and changing in nature. Fifty trade agreements were in force in 1990.
In 2017, there were more than 280. In many trade agreements, negotiations today go beyond tariffs and cover several policies that influence trade and investment in goods and services, including rules across the border, such as competition policy, government procurement rules and intellectual property rights. ASAs covering tariffs and other border measures are „superficial” agreements; THE RTAs, which cover a larger group of policies, at and below the border, are „deep” agreements. ASEAN members have a total population of over 650 million. Indonesia accounts for more than 40 per cent of the region`s population and the population has been the most opposed to the agreement.   The amendments relating to the free trade area framework mainly concerned Vietnam.
