二、国民待遇原则的适用
（一）货物贸易领域的国民待遇原则
关税与贸易总协定中的国民待遇，指外国进口产品所享受的待遇不低于本国同类产品、直接竞争或替代产品所享受的待遇。国民待遇义务适用于每一具体产品，各进口成员不能在不同产品、不同批次产品中进行国民待遇的平衡，不得以对某些产品提供优惠待遇为借口对其他产品拒绝国民待遇。货物贸易领域中的国民待遇原则主要体现于GATT 1994第3条第1款、第2款、第4款、第5款和第7款。
1. The contracting parties recognize that internal taxes and other internal charges, and laws, regulations and requirements affecting the internal sale, offering for sale, purchase, transportation, distribution or use of products, and internal quantitative regulations requiring the mixture, processing or use of products in specified amounts or proportions, should not be applied to imported or domestic products so as to afford protection to domestic production.
