experts from OECD countries came together, calling upon "national governments to undertake actions to bring the BRC concept into being in concert with the international scientific community". BRCs are "repositories and providers of high-quality biological materials and information". As international security issue For a long time, health security or biosecurity issues were not considered as an international security issue, especially in the traditional view of international relations. However, some changes in trend have contributed to the inclusion of biosecurity (health security) in discussions of security. As time progressed, there was a movement towards securitisation. Non-traditional security issues such as climate change, organised crime, terrorism, and landmines came to be included in the definition of international security. There was a general realisation that the actors in the international system not only involved nation-states but also included international organisations, institutions, and individuals, which ensured the security of various actors within each nation became an important agenda. Biosecurity is one of the issues to be securitised under this trend. On 10 January 2000, the UN Security Council convened to discuss HIV/AIDS as a security issue in Africa and designated it a threat in the following month. The UNDP Millennium Development Goals also recognise health issues as international security issue. Several instances of epidemics such as SARS increased awareness of health security (biosecurity). Several factors have rendered biosecurity issues more severe: there is a continuing advancement of biotechnology, which increases the possibility for malevolent use, evolution of infectious diseases, and globalising force which is making the world more interdependent and more susceptible to spread of epidemics. Controversial experiments in synthetic biology, including the synthesis of poliovirus from its genetic sequence, and the modification of flu type H5N1 for airborne transmission in mammals, led to calls for tighter controls on the materials and information used to perform similar feats. Ideas include better enforcement by national governments and private entities concerning shipments and downloads of such materials, and registration or background check requirements for anyone handling such materials. Challenges Diseases caused by emerging viruses are a major threat to global public health. The proliferation of high biosafety level laboratories around the world has resulted in concern about the availability of targets for those that might be interested in stealing dangerous pathogens. The growth in containment laboratories is often in response to emerging diseases, and many new containment labs' main focus is to find ways to control
