There are no multilateral agreements whose main objective is to regulate marine pollutants in the air, but these pollutants fall within the general scope of several regional agreements dealing with a wide range of sources of marine pollution. Of these, only the Baltic Sea, North-East Atlantic and Mediterranean agreements include specific regulatory measures. In addition, the 1979 Geneva Convention on Long-Distance Cross-Border Air Pollution provides for detailed regulation of emissions of many air pollutants emitted by participating countries in the Northern Hemisphere. Although not directly aimed at marine pollution, the Geneva Convention is likely to offer indirect benefits to the marine environment. Multilateral trade agreements are treaties between three or more nations that wish to trade with each other. Trade agreements have exploded over the past 70 years, when nations realized that international trade was essential to national health. If trade agreements are concluded between several countries, there are pros and cons. The third drawback is common to each trade agreement. Some businesses and parts of the country are suffering from the disappearance of trade borders. The MAI has attracted widespread criticism, particularly from non-governmental workers` and environmentalists, which has led to numerous demonstrations and protests around the world. In countries such as Canada and France, the MAI has been seen as a threat to local cultures and national sovereignty. This finally led, in 1998, to France`s withdrawal from the MAI negotiations. After France`s withdrawal, many countries followed and the draft treaty was rejected in 1999.
Today, the TRIM agreement remains the most important legal framework within the WTO for the EU directly at the multilateral level. The Trans-Pacific Partnership would have been larger than NAFTA. Negotiations ended on 4 October 2015. After becoming president, Donald Trump withdrew from the agreement. He promised to replace them with bilateral agreements. The TPP was located between the United States and eleven other countries bordering the Pacific Ocean. It would have abolished tariffs and standardised trade practices. In approving the negotiations, the OECD Council of Ministers set itself the goal of achieving a „broad multilateral framework for international investment, with high standards for the liberalisation of investment regimes and the protection of investment and effective dispute resolution procedures.“  The aim was to create more harmonised, secure and stable investment conditions and to regulate investments in a more coherent, transparent and enforceable manner.
Although the agreement is negotiated between Member States, an open agreement should be concluded to which non-OECD members can join on a negotiating basis.  A multilateral treaty is a particular form of multilateral treaties. A multilateral treaty is a contract between a limited number of states that have a particular interest in the subject of the treaty.  The main difference between a multilateral treaty and other multilateral treaties is that the availability of reserves is more limited by a multilateral treaty. Given the limited nature of a multilateral treaty, full cooperation between the parties is necessary for the purpose of the treaty to be respected. Therefore, reservations about multi-lateral contracts are not admissible without the agreement of all other contracting parties. This principle is codified under international law by Article 20, paragraph 2, of the Vienna Convention on Treaty Law: the European Commission represents the EU for most WTO meetings. A special committee is consulting with the European Commission to negotiate trade agreements on behalf of member states. The Commission`s work as a whole takes into account the broader aspects of COMMUNITY policies.
