The aim of the amendments was to prevent Western technology companies from selling to governments that are known to be abusing human rights. However, some technology companies have expressed concern that the scope of controls may be too broad, limiting the ability of security researchers to identify and correct security vulnerabilities. Google and Facebook have criticized the agreement for the restrictions they will set for activities such as penetration testing, information exchange on threats and bounty programs.   They argue that the restrictions will weaken the security of participating nations and will do little to contain the threats of non-participating nations.   When the Cold War ended in 1991 with the dissolution of the Soviet Union, the East-West decision faded. COCOM members then agreed to end the group and create a new multilateral agreement, temporarily known as the “New Forum.” However, participating states agreed to continue the use of COCOM checklists as a basis for overall domestic export control until the new regime can be defined. The twelfth plenary session on 5 and 6 December in Vienna celebrated the va`s tenth anniversary and was chaired by Australian Ambassador Peter Shannon. Parliament has successfully adopted a number of checklist changes, while expressing a desire to establish a dialogue with the VA panel and the missile technology control regime to improve the regime`s ability to keep pace with the progress of technologies, market trends and international security. In addition, the plenary decided to make available to the public two best practices for Implementing Intangible Transfers of Technology Controls and Best Practice Guidelines for the Licensing of Its Licensing on the Basic List and Sensitive List of Dual-Use Goods and Technologies – to complement the plenary agreement to maintain a high priority for transparency and contact with non-participating states and international organisations to promote strengthening export controls. The draft agreement is presented in a document entitled “Guidelines and Procedures, including Original Elements.”  The list of restricted technologies is divided into two parts, the “double-use goods and technology list” (also known as the Basic List) and the “Ammunition List.” The basic list consists of ten categories based on increasing sophistication: at the US-Russian summit in Vancouver, Canada, on April 4, 1993, the Russian and U.S. presidents agreed on the need for a quick resolution to non-proliferation and missile technology issues, in accordance with the principles of existing international agreements. They decided to cooperate to remove barriers to Russia`s access to the global high-tech market and related services.
