Regional trade agreements (ATRs) have multiplied over the years and have achieved, including a significant increase in major multilateral agreements being negotiated. Non-discrimination between trading partners is one of the fundamental principles of the WTO; However, reciprocal preferential agreements between two or more partners are one of the exceptions and are allowed by the WTO subject to a number of provisions. Information on WTO-notified ATRs is available in the RTA database. BAFTAs were created to prepare countries to join the EU. That is why the BAFTAs were more than an EU initiative than a willingness to trade between the Baltic States: they were more interested in access to other European markets.  The Baltic Free Trade Area was a free trade agreement between Estonia, Latvia and Lithuania, which was concluded between 1994 and 2004. The EU shares its internal market with three EFTA members on the European Economic Area agreement and the rest of the EFTA member, Switzerland, on bilateral agreements. OFFTA was part of the general cooperation between the three countries of the Baltic Assembly, modelled on Nordic cooperation (see Nordic Council). In addition to the free trade area, they have established a common visa zone. Heads of state and government continue to meet regularly, but the Assembly is now focusing on international issues, including economic development and military cooperation due to its proximity to Russia.
 In October 2018, the EU and Singapore signed a free trade agreement and an Investment Protection Agreement (PPI). The EU-Singapore Free Trade Agreement is the first free trade agreement between the EU and a member of the Association of Southeast Asian Nations (ASEAN). The free trade agreement is expected to be implemented in 2019. Deep trade agreements are an important institutional infrastructure for regional integration. They reduce business costs and set many rules in which economies are active. If designed effectively, they can improve political cooperation between countries and thus promote international trade and international investment, economic growth and social well-being. Studies by the World Bank Group have shown that the Commonwealth of Independent States has been negotiating an IEC free trade area since 1994 and that eight countries have agreed on the creation of a free trade area in 2011. These are; Russia, Ukraine, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, Armenia and Moldova. In addition, Belarus, Kazakhstan, Russia, Armenia and Kyrgyzstan form the Eurasian Economic Union, including a customs union and an internal market.
