Despite the benefits offered by RTA, there are legitimate concerns about the impact these agreements can have on local businesses and consumers. Opening up national markets to new sources of competition can jeopardize local producers and undermine environmental principles. Most people in countries where cross-border agreements have been implemented are very familiar with these issues. Therefore, the protection of businesses, consumers, workers and the environment must be guaranteed for ATRs to be fully effective. Several important new regional agreements are being developed: a multilateral agreement increases trade for all countries involved. Their companies enjoy low tariffs that make exports cheaper. Multilateral agreements also align trade rules between all companies in all countries, allowing companies to save on legal costs because they all follow the same rules in each country. 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. The number of bilateral investment agreements increased rapidly during the 1990s. countries and investors are inspired by increased security regulation, security and mobility of their investments, after it became clear that the Uruguay Round Trade Investment Measures (TRIMS) Agreement, the Trade-Related Intellectual Property Rights (ADPIC) Agreement and the General Trade in Services Agreement (GATS) only took into account some of the investment-related concerns and that investors were not sufficient security and strong controls by multinationals.  In addition to these instruments, the World Bank adopted guidelines in 1992 for the treatment of foreign direct investment.
 In 1994, the Energy Charter Treaty set an example of a multilateral investment agreement, but limited to the energy sector. Multilateral trade agreements are trade agreements between three or more nations. The agreements reduce tariffs and facilitate the import and export of companies. Because they belong to many countries, they are difficult to negotiate. The money the Fund receives from a resilient participant is used by the Fund to exchange special drawing rights held by participants in proportion to the amount of each participant`s participation in special drawing rights at the time the Fund receives the coin for its cumulative net allocation. Special drawing rights thus collected and special drawing rights received by a participant terminate, in accordance with the provisions of this agreement, in order to satisfy any waterproofing agreement or scheduleD rates due and charged at this rate are void. As a result, the pros and cons of the multilateral agreement are the subject of much discussion.
