Unlike the Pacific, Europe generally has a well-developed parking system and a series of European laws and multilateral agreements to protect them. However, the effectiveness of this protection is not uniform and the main idea of the IUCN European Programme (2005-2008) is to improve this protection in the most vulnerable areas. This broad scope makes them more robust than other types of trade agreements as soon as all parties sign. Bilateral agreements are easier to negotiate, but only between two countries. Much has been written recently about the Multilateral Agreement on Investment (MAI), negotiated by OECD countries. Perhaps the critics of those who want to extend such an agreement between other countries have spoken even more. The fourth advantage is that countries can negotiate trade agreements with more than one country at the same time. Trade agreements are subject to a detailed authorisation procedure. Most countries would prefer to ratify an agreement covering many countries at the same time. In addition to national legislation and bilateral or regional agreements, multilateral environmental agreements (EAs) form the global international legal basis for global efforts to address certain environmental issues. MEAs, which are relevant to mangrove conservation, offer the opportunity to strengthen management, offer a common approach to environmental issues and provide a certain level of protection, at least on paper (Van Lavieren et al., 2012).
The designation of mangrove areas under international agreements or agreements may mean further examination and increased pressure for intelligent management. Global agreements can also provide institutional support for conservation efforts. Protected areas such as the Ramsar Wetlands Convention, the UNESCO World Heritage Convention and UNESCO`s Human and Biosphere Programme can improve the reputation and international profile of a given site (Van Lavieren et al., 2012). The designation may also facilitate a degree of assistance and cooperation (financial and technical) (Spalding et al., 2010). MEAs can be used as environmental management tools and apply and strengthen management approaches such as protected areas, national adaptation programmes and integrated coastal area management (Section D). MEAS plays a crucial role in the overall framework of environmental laws and conventions. The Multilateral Investment Agreement (MIA) was a draft agreement negotiated between 1995 and 1998 under secret negotiation between members of the Organisation for Economic Co-operation and Development (OECD).  It attempted to create a new body of universal investment laws that would give companies unconditional rights to participate in financial transactions around the world, regardless of national laws and civil rights. The project gave companies the right to sue governments when national health, labour or environmental laws threatened their interests.
