2. With a view to gradually liberalizing investment conditions, the parties reaffirm their commitment to review the regulatory framework for investment, investment environment and investment flows between them, in line with their obligations in international investment agreements, no later than three years after this agreement comes into force. 3. Chile undertakes, at the request of one Member State, to conclude bilateral agreements with individual Member States governing the specific readmission obligations between Chile and the Member State concerned, including an obligation to readmission nationals of other countries and stateless persons. All agreements concluded outside the WTO framework (which provide additional benefits beyond the WTO level, but which apply only between signatories and not other WTO members) are considered to be preferred by the WTO. Under WTO rules, these agreements are subject to certain requirements, such as WTO notification and general reciprocity (preferences should apply equally to each signatory to the agreement), where unilateral preferences (some of the signatories enjoy preferential market access to the other signatories without reducing their tariffs) are allowed only in exceptional circumstances and as a temporary measure.  1979 — under. (a) (2) (D) (ii) pub. L. 96-39 referred to the evaluation standards in Section 1402 of this title.
(c) the establishment of a forum for consultation and early resolution of issues which, within the framework and for the purposes of this section, act or may act as unnecessary impediments to exchanges between the parties; Trade agreements, any contractual agreement between states on their trade relations. Trade agreements can be bilateral or multilateral, i.e. between two states or more than two states. Trade pacts are often politically controversial because they can change economic practices and deepen interdependence with trading partners. Improving efficiency through “free trade” is a common goal. Most governments support other trade agreements. (g) technical assistance to strengthen health and plant health control systems to support, where possible, the promotion of equivalency and mutual recognition agreements. There are significant differences between unions and free trade zones. Both types of trading blocs have internal agreements that the parties enter into to liberalize and facilitate trade between them. The key difference between unions and free trade zones is their approach to third parties [lack of ambiguity needed]. While a customs union requires all parties to apply and maintain identical external tariffs on trade with non-parties, parties to a free trade area are not subject to such a requirement. Instead, they can set and maintain any customs regime for imports from non-parties, as they see as necessary.
 In a free trade area without harmonized external tariffs, the parties will adopt a system of preferential rules of origin to eliminate the risk of trade diversion [necessary ambiguities].  1.
