The summit is designed to foster sustainable development and enhance cooperation across various sectors, including trade, investment, and technology. A key focus will be the establishment of a new framework for cooperation in artificial intelligence, aimed at bolstering economic security through advancements in mineral resource development and supply chain management. Additionally, the agenda includes discussions on infrastructure development to improve transport routes linking Central Asia with Europe via the Caspian Sea, a strategic move to bypass reliance on Russia.

For the Central Asian nations, this summit presents an opportunity to integrate into global value chains while avoiding the pitfalls of being mere raw material suppliers. Kazakhstan, in particular, is expected to finalize over 40 agreements worth more than $3.7 billion during the summit, covering sectors such as energy, renewables, and digitalization. Japan's ambassador to Kazakhstan, Yasumasa Iijima, has emphasized Kazakhstan's potential as a logistics hub, crucial for developing the Trans-Caspian route.

Japan's renewed engagement with Central Asia is driven by its need for stable energy supplies and critical minerals, particularly from Kazakhstan, which produces over 40% of the world’s uranium. The summit aligns with Japan's broader economic security strategy, which seeks to diversify supply chains and reduce dependence on single-source suppliers. This pivot is underscored by Japan's commitment to long-term development financing and technology transfer, contrasting with the more coercive approaches of other global powers in the region.

While the summit is viewed positively by many, some analysts caution that Japan's approach may still be perceived as secondary compared to the influence of Russia and China in Central Asia. Critics argue that Japan must ensure its initiatives do not merely serve as a counterbalance to these powers but genuinely address the needs and aspirations of Central Asian states.
