According to the Commission on Global Governance (1995), global governance refers to “the sum of the many ways in which individuals and institutions, public and private, manage their common affairs. It is the ongoing process through which conflicts or different interests can be resolved and cooperative action can be taken.” Some of the key actors involved in the global governance process include states, international organizations (IOs), regional organizations (ROs), and non-governmental organizations (NGOs). Global governance takes place in various thematic areas including security, economic development, environmental protection and so on. Different states and organizations have different or even conflicting interests. However, as globalization continues and the world becomes more interconnected than ever, global governance or cooperation between different actors is taking on an increasingly significant role on the international stage. Some critics view global governance rather negatively as they believe the current system lacks efficiency and effectiveness. In this article, however, I will argue that global governance is implemented most effectively in maintaining world security and promoting economic development, while least effective in protecting and conserving the environment. Therefore, despite the limitations of the existing mechanism, global governance still largely represents a positive development in world affairs. International organizations and states play a vital role in maintaining world peace and security. The United Nations (UN), in particular, is the hub of global governance with respect to maintaining world peace. The UN provides general guidelines to all states on how to resolve potential conflicts and maintain international standing. Department of Public Information (1995).
