The present international order is changing substantially as power is being redistributed among a greater number of important actors and is no longer centralised around one great power. The shifting balance of power has also generated pressure for greater reform of international governance institutions better to reflect current political, economic and military realities. In the United Nations Security Council (UNSC), International Monetary Fund (IMF) and World Bank, for example, their outdate governance arrangements, which have yet to reflect current economic shifts (including in major emerging economies and the Global South), have continued to cause questions regarding their legitimacy, representation and efficacy.

The study adopts a qualitative research design based on documentary analysis of academic literature, official policy documents, government statements, multilateral declarations, and reports of international organizations. It evaluates India's engagement with major multilateral platforms, including the G20, BRICS, the United Nations, the International Solar Alliance, and the Voice of the Global South initiative, to assess its contribution to institutional reform and international cooperation. The analysis argues that India’s foreign policy has evolved beyond traditional strategic balancing to embrace coalition-building, development partnerships, climate diplomacy, and digital public infrastructure as key instruments of global engagement. The above measures has only led India to reinforce her credentials as a connecting country between the developed and developing world and pushed the agendas of the Global South. Nevertheless, India’s leadership continues to face significant challenges arising from geopolitical rivalries, institutional resistance to reform, and the complexities of balancing strategic autonomy with expanding strategic partnerships. Therefore, India's diplomatic reach, economic prowess, and norm-based activism should provide it with an important role in constructing an open, inclusive, and adaptable model for the governance of the global order of the 21st century.
