There have been several achievements in the field of trade cooperation such as adopting several laws and regulations, enhancing economic citizenship, and setting up mutual commissions. The following are the most important achievements:

• Permitting GCC citizens to engage in retail trade as of March 1, 1987, and wholesale trade as of March 1, 1990, in any Member State and be treated equally, (Resolution of the Supreme Council, 7th session, December 1986).
• Allowing the GCC establishments and production plants to open offices for commercial representation in any Member State (Resolution of the Supreme Council, 12th session, December 1991), as well as permitting them to import and export national products from and into any Member State without a local agent.
• Establishing the GCC Commercial Arbitration Center and its bylaws thereof, under the Resolution of the Supreme Council at the 14th session, Riyadh, December 1993. The Center which was established in March 1995 is based in Bahrain. It provides an acceptable mechanism to settle commercial disputes. It addresses commercial disputes among GCC citizens or non GCC-nationals, being natural or legal persons. In addition, it addresses commercial disputes arising from implementing the economic agreements and their resolutions. The Center also organizes arbitration symposiums and seminars in all member states.
• Adopting the bylaw of the GCC Accounting and Auditing Commission (AAC), under the Resolution of the Supreme Council at the 19th session, Abu Dhabi, December 1998. The AAC has started its activities after the foundation phase.
• Establishing the GCC Standardization Organization (GSO) under the Resolution of the Supreme Council at the 23rd session, Doha, December 2002. The GSO prepares, approves, and publishes GCC products' standards. It also unifies various standardizations and follows its application in cooperation and coordination with the standardization organizations in member states. This should develop production and service sectors, promote intra-GCC trade, protect consumers, environment and public health, and encourage GCC agricultural products and industry. Thus, the GSO supports GCC economy and helps reduce technical barriers on trade in line with the objectives of the GCC Customs Union and Common Market.
• Applying equal treatment to all GCC citizens in the field of stock ownership, company corporation, and elimination of relevant restrictions by 2003, (Resolution of the Supreme Council, 23rd session, Doha, December 2002).
• Adopting the document of Common Trade Policy that unifies GCC External Trade Policy, (Resolution of the Supreme Council, 26th session, Abu Dhabi, December 2005).
• Adopting the GCC Trademark Law (Resolution of the Supreme Council, 33rd session, Manama, December 2012).
• Permitting Gulf companies to have branches in the GCC States, and receive equal treatment similar to local companies according to the Supreme Council's decision at the 31st session in Abu Dhabi, December 2010.
• Participation of the Federation of GCC Chambers in the meetings of the technical committees that deal directly with the private sector according to the Supreme Council's decision at the 11th Consultative meeting, in Riyadh, May 2009.

Efforts are exerted to turn a number of reference trade laws and regulations into binding GCC laws. Other new draft laws are being concluded such as Common Trade law, Unified law of Commercial Agencies, Common Commercial Registration Law, GCC Commercial Fraud Control, GCC Consumer Protection law, GCC Competition Law, GCC Commercial Secrets Law, Unified Law for Supervision and Control of Insurance Activities, Unified Law of Auditing and Common Electronic Transactions law.
