A high-level meeting between the United States and the five Central Asian countries—Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan—is scheduled for this weekend in Samarkand, Uzbekistan, under the C5+1 diplomatic format. Led by U.S. Secretary of State Marco Rubio, the ministerial gathering marks an intensified focus on business and investment, with approximately 200 American business representatives attending to expand on economic agreements reached during last year’s 10th anniversary summit at the White House.
Established in 2015, the C5+1 framework serves as the primary platform for U.S. engagement in Central Asia. The choice of Samarkand as the meeting location carries symbolic significance, given the city’s historic role along the Silk Road and its position as a center for strengthening economic ties. The timing of this meeting follows a recent C6 formation in Avaza, Turkmenistan—a new diplomatic group that includes the five Central Asian nations plus Azerbaijan—and precedes the Organization of Turkic States summit planned for later this month in Ankara, Turkiye. While these groupings differ slightly in membership, their overlap enables coordination and underscores the rising diplomatic and economic importance of the region.
Central Asia’s strategic value has grown amid heightened global competition for energy resources and critical minerals. The region’s abundant oil and natural gas reserves, along with vital raw materials, have attracted international attention as countries seek to diversify energy supplies. Consequently, the dialogue at the C5+1 meeting is expected to emphasize global energy markets and opportunities for expanded trade and investment.
Alongside economic concerns, geopolitical dynamics are expected to influence discussions. Although not likely to dominate the public agenda, the ongoing war involving Iran and the repercussions of Russia’s invasion of Ukraine are important factors affecting regional stability and economic development. Officials are anticipated to address these issues in broader policy conversations.
Another key but less visible topic may be the future of the C5+1 secretariat. Observers note potential interest in developing this mechanism into a more permanent institution to sustain cooperation between summits, akin to formal arrangements used by Central Asia in dealings with China.
Looking forward, experts suggest several paths for Washington to deepen its engagement in the region. Sustaining momentum through continued high-level visits is a priority, with calls for ongoing Cabinet-level participation and a presidential visit. To date, no sitting U.S. president has visited Central Asia. Given the Trump administration’s focus on the region, it has been proposed that President Donald Trump could become the first. Additionally, there is discussion about expanding the C5+1 platform to include Azerbaijan, following the example of the C6 format. Proponents argue that Azerbaijan’s geographic position as a gateway to Central Asia and its close economic and cultural ties with the region justify its inclusion.
Efforts to promote normalization between Armenia and Azerbaijan, initiated at a historic August 2025 meeting at the White House, remain a priority, though progress has been slow. Renewed U.S. attention toward advancing peace talks is expected to feature among diplomatic goals.
The upcoming C5+1 meeting in Samarkand represents a significant moment in U.S.-Central Asia relations, reflecting both shared economic interests and complex geopolitical challenges shaping this increasingly pivotal region.
