A common market is a first step towards an internal market and may initially be limited to a free trade area with relatively free capital and services, but less advanced in reducing other barriers to trade. By removing customs barriers and eliminating discrimination in international trade, gatt aims: as has already been said, the fundamental pillar of GATT was the granting of all concessions to all GATT Member States. GATT members are free to apply any obligations they wish to non-members, but members should receive the highest remuneration. The original GATT provided for a derogation from this rule for countries that constituted a customs union or free trade area that had to be reviewed by GATT members.  Many policymakers and businessmen see the lack of progress in trade liberalization as a temporary problem and believe that these barriers would be overcome if the trading community would improve its case for the benefits of trade. Some duty-free traders consider globalization to be inevitable; From this perspective, the United States may suffer some setbacks, but over time, globalization will inevitably continue. But this is not necessarily the case. A better approach is to seriously consider the concerns of critics and develop a trade policy that better promotes U.S. interests. One of the most important achievements of GATT has been trade without discrimination. Each signatory member of the GATT must be treated in the same way as another.
This is called the most-favoured-nation principle, which has been taken up in the WTO. One of the practical results was that once a country negotiated a tariff reduction with certain other countries (usually its major trading partners), the same reduction would automatically apply to all GATT signatories. It is true that there were alternative clauses that allowed countries to negotiate waivers when their domestic producers were particularly adversely affected by tariff reductions. The Uruguay Round of Agriculture Agreement remains the main agricultural trade liberalization agreement in the history of trade negotiations. .
