In June 2025, India's National Security Advisor (NSA), Ajit Doval, emphasized the importance of a unified counter-terrorism stance during the SCO Summit held in China. This summit functioned as a significant diplomatic platform comprising countries from the Shanghai Cooperation Organization.

The reason why the SCO Summit was an appropriate venue for such discussions is due to its membership, which includes several countries that face threats from terrorism and extremism. Moreover, the platform provides an opportunity for member states to collaborate in countering terrorism through intelligence sharing, joint exercises, and institutional coordination.

Let’s analyze the options to understand why the SCO Summit was the selected platform:

• EU Summit in Brussels: This summit primarily focuses on discussions involving European Union member states concerning economic policy, human rights, and political issues pertinent to the EU. Although counter-terrorism is a topic discussed within the EU, the context and participants differ from the SCO's focus.
• G20 Summit in New Delhi: The G20 primarily addresses international financial stability, economic policy coordination, and sustainable development. While counter-terrorism can be a topic of interest, it is not the central theme.
• ASEAN Summit in Jakarta: ASEAN focuses on regional issues in Southeast Asia, and although counter-terrorism cooperation is part of its agenda, the geographical and political scope is distinct from that of the SCO.

In contrast, the SCO Summit in China focuses explicitly on regional security concerns, especially given its composition involving countries like Russia, China, and India, all of which have vested interests in countering terrorism.

Thus, NSA Ajit Doval's push for a unified counter-terrorism stance was most relevant and impactful at the SCO Summit in China, making it the correct answer to this question.
