Vietnam and the WTO January 11, 2007: Vietnam officially joins the World Trade Organization Protocol of Accession including schedules of goods and services, based on report of the Working Party and bilateral negotiations between Vietnam and all interested member states Conclusion of a decade-long process of application and accession, extensively laying out the minute details of Vietnam s interaction with the international economic community.
Vietnam s Accession Protocol Schedule of Goods Product Bound Rate (Accession) Bound Rate (Final) Pocket lighters (pistol shaped) 35 25 Ship propeller oil seal rings 10 5 Rhinoceros horns; ivory powder 5 Imitation jewelry (bangles) 30 25 Cashew nuts (shelled) 40 25 Decoy calls (noisemakers) 3 Schedule of Services Service Motion picture production Freight Transportation Restrictions Only in the forms of business cooperation contracts or joint ventures with Vietnamese partners... foreign capital contribution may not exceed 51% of the legal capital.... the capital contribution of the foreign side not exceeding 49%... 100% of joint-venture s drivers shall be Vietnamese citizens.
GATT Article XXVI:5(c) and Post-Colonial States Vietnam could have joined earlier, before the GATT was recast as the WTO, with much less onerous restrictions: If any of the customs territories, in respect of which a contracting party has accepted this Agreement, possesses or acquires full autonomy in the conduct of its external commercial relations and of the other matters provided for in this Agreement, such territory shall, upon sponsorship through a declaration by the responsible contracting party establishing the above-mentioned fact, be deemed a contracting party. (emphasis added) GATT Charter, article XXVI:5(c)
Variation in Post-Colonial GATT/WTO Accession Many states joined quickly upon independence: Nigeria 1960 1961 Bangladesh 1971 1972 Belize 1981 1983 Several waited, then joined pre-transition: Mozambique 1975 1992 Guinea 1958 1994 Qatar 1971 1994 Others never joined the GATT, then began WTO accession: Vietnam 1954 2007 Cape Verde 1975 2008 Algeria 1962 in negotiations
Post-Colonial States: Years Until Accession
Question How can we explain the substantial variation in the speed and timing of post-colonial states accession to the GATT/WTO? Why did some countries join under Article XXVI:5(c) while others did not? What determines whether and when states choose to join?
WTO Literature Dynamics of trade round negotiations (Baldwin 2007; Jones 2009; Odell 2009) Effects of GATT/WTO membership (Rose 2004/2005; Goldstein et al 2007; Subramanian and Wei 2007) Dispute resolution (Bush 2000; Allee and Huth 2006; Sattler and Bernauer 2008) Overlap between the GATT/WTO and PTAs (Davis 2006; Busch 2007; Naoi 2009) Developing states and the WTO (Drahos 2003; Clapp 2006; Davis 2006; Patel 2008)
GATT/WTO Accession and Defensive Market Access States will join the GATT/WTO more quickly when when: They are heavily dependent on trade with existing member states They lack viable outside options (PTAs) to ensure market access with key trading partners
Alternative Arguments Democracy or democratization Costly signaling Policy lock-in Geopolitical ties Ties to prominent members/nonmembers Colonial connections Regional diffusion Neighboring states actions shift incentives Peer states experiences provide information

Vietnam Revisited Increasing trade with GATT/WTO members Policy shift toward trade openness as an engine of economic growth and stability Increasing trade with the United States following 1994 normalization and 2001 Bilateral Trade Agreement Accession of Hong Kong (1995), China (2001), Taiwan (2002), and Cambodia (2004) Weak PTA protection Loss of PTA trade with the Soviet Union Vulnerable U.S.-Vietnam BTA Limited ASEAN Free Trade Area
Vietnamese GATT/WTO and PTA Trade Coverage
Conclusions The need to protect market access is the central determinant of whether and when states choose to join the GATT/WTO Other arguments... Democracy or democratization: limited, mixed evidence Geopolitical ties: some evidence negatively, none positively Regional diffusion: no evidence Economic factors... Trade openness: positive, but weak evidence GDP and GDP per capita: not consistently significant Institutional status... Non-member status: positive (possible selection effect)
Implications Evolving economic ties drive participation in multilateral trade institutions PTAs acting as substitutes, not complements, for GATT/WTO membership States decisions of whether and when to join international organizations is affected by the pre-existing context of their institutional membership
