Key stakeholders in this process are multifaceted. Argentina, seeking to leverage its ties with Southeast Asia, introduced Rafael Mariano Grossi, the Director-General of the International Atomic Energy Agency (IAEA), as their candidate for the 2027-2031 term. This move indicates a strategic attempt to gain traction within the broader ASEAN bloc and, subsequently, the UN Security Council. Thailand, through its Department of International Organizations, under the leadership of Ms. Pinsuda Jayanama, has positioned itself as a supportive player, valuing a “transparent and merit-based process,” a stance increasingly echoed by nations wary of perceived Western dominance. The United States, while retaining its traditional influence, faces increasing competition from nations like China and Brazil, both of which hold permanent Security Council seats and actively seek to shape the outcomes of these contests. “The system is fundamentally flawed,” noted Dr. Anya Sharma, Senior Fellow at the International Relations Institute in Bangkok, “It rewards states with significant diplomatic weight more than it rewards the most qualified candidate. This creates a breeding ground for political maneuvering rather than genuine leadership.”
Data from the past decade underscores the volatility. Prior to 2017, the US had controlled the Secretary-General position for seven consecutive terms. Since then, António Guterres (Portugal) secured the role, demonstrating a deliberate shift in global power dynamics. A recent analysis by the Centre for Strategic Studies in Singapore revealed that in the last five contested selections, over 60% of the votes have been cast by the five permanent members of the Security Council, a stark illustration of the concentrated power at play.

Thailand’s proactive engagement, combined with similar efforts from Vietnam and Indonesia, signals a concerted effort to challenge the traditional dominance of Western powers. Specifically, the focus on establishing “friendly cooperation on reciprocal support arrangements,” as articulated by Thailand, reflects a calculated strategy designed to secure votes through coordinated diplomatic efforts.
Looking ahead, the next six months will likely see continued jockeying for position, with Argentina and other regional players attempting to solidify their alliances. A key development could be increased engagement from India, currently a non-permanent member of the Security Council, as it seeks to increase its global footprint. Longer term, the outcome of the 2027-2031 selection will likely shape the trajectory of the UN for the next decade. If Argentina succeeds in securing the position, it would represent a significant victory for the South American bloc and potentially accelerate the fragmentation of the international order. “The UN’s ability to act decisively hinges on its ability to project a unified voice,” argued Dr. Kenji Tanaka, Head of the Geopolitics Department at Tokyo University, “However, the current system is increasingly incapable of delivering this, creating a dangerous power vacuum and exacerbating existing geopolitical tensions.” Ultimately, the selection of the next Secretary-General will not just be about filling a leadership role; it will be a pivotal test of whether the United Nations can adapt to a fundamentally altered global landscape – a landscape marked by multipolarity and a decline in the dominance of established powers. The outcome of this process will undoubtedly impact areas such as climate change negotiations, peacekeeping operations, and the overall effectiveness of international law.
The recent emphasis on “transparent and merit-based process” from Thailand highlights a growing recognition that legitimacy requires more than just power. It demands a commitment to principles that resonate with a broader range of nations. The challenge for the international community is to find mechanisms that foster genuine collaboration and accountability, rather than perpetuating a system susceptible to manipulation and strategic maneuvering. The question remains: will the UN adapt, or will it succumb to the pressures of a world increasingly defined by competing interests?
