Note: Under common law, the agreement is a necessary part of a valid contract. Under the Single Code of Trade, paragraph 1-201 (3), the agreement is the good deal of the contracting parties, as they are explicitly presented by their language or implicitly by other circumstances (as transactions). Pending the completion of the three-year harmonization program, members are expected to ensure transparency of their rules or origin; They should be managed in a coherent, coherent, impartial and rational manner; and they are based on a positive standard. The GATT does not have specific rules for determining the country of origin of goods in international trade. Each party has been free to set its own rules of origin and may even maintain several different rules of origin depending on the purpose of the regulation. The authors of the general agreement said that the rules of origin should be maintained: … within the province of each importing country, determine whether the goods are in fact from a particular country, in accordance with the provisions of its law for the application of the provisions of the most favoured nation (and for other purposes of the GATT). Article VIII:1, point (c), of the General Agreement, which deals with import and export royalties and formalities, states that the parties also recognize the need to minimize the frequency and complexity of import and export formalities, to reduce and simplify import and export documentation requirements, and interpretive note 2 of this article that this would be consistent if consistent. , when importing products from the territory of one party in another party`s territory, the presentation of certificates of origin should be only to the extent necessary, to the extent necessary. In standard English, for example, you can say I am or it is, but not “I am” or “it is.” This is because the grammar of the language requires that the verb and its subject coincide personally. The pronouns I and him are respectively the first and third person, just as the verbs are and are. The verbage form must be chosen in such a way as to have the same person as the subject, unlike the fictitious agreement based on meaning.   In American English, for example, the expression of the United Nations is treated as singular for the purposes of concordance, although it is formally plural.
