China is the region’s top trading partner, but Russia retains vital influence. And in recent years, the United States has tried to make inroads, too.

Chinese President Xi Jinping reached Kazakhstan on Monday to attend the second China–Central Asia Summit, a high-stakes diplomatic gathering aimed at deepening Beijing’s economic and strategic ties with the region.

The summit, which will be held on Tuesday in the Kazakh capital Astana, comes at a time when China is intensifying its outreach to Central Asian countries amid shifting global power alignments — and mounting tensions in neighbouring Iran, which is roiled in an escalating conflict with Israel.

The summit will bring together the heads of state from all five Central Asian nations — Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan — along with Xi.

The Astana summit also carries symbolic weight: it is the first time that the five Central Asian nations are holding a summit in the region with the leader of another country.
