For centuries, international politics was considered as an arena of the states. However, with the rise of the free-market economy, globalisation, international institutions and technology, many non-state actors such as international non-governmental organisations (INGOs) started sharing the power corridors along with the states. Contemporary academic literature cites many examples where INGOs has played important roles in decision-making processes. The flow of development aid from developed countries to the developing countries through INGOs has enhanced their role in international development. Similarly, many developing countries started outsourcing social services such as health and education to INGOs. International laws, on one hand, protect INGOs to mobilise additional financial resources from developed states. INGOs contributed to humanitarian diplomacy especially in climate change and banning landmines. INGOs also face some criticism in terms of poor accountability and legitimacy. Southern countries sometimes perceive INGOs as carriers and promoters of western liberal agenda.
