In November 2025, Washington hosted the presidents of the five Central Asian nations to mark the 10th anniversary of the C5+1 diplomatic platform. What emerged from the summit was not just celebration—but a redefinition.
Once framed as a multilateral vehicle for addressing security, governance, and climate challenges, the C5+1 now functions as a streamlined tool for bilateral economic diplomacy. The event signaled a fundamental policy shift: the US now favors transactional commercial engagement over complex regional cooperation.
The Evolution of the C5+1
Originally launched in 2015, the C5+1 brought Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan into strategic dialogue with the United States. A high point of the platform was the 2023 New York Declaration under President Biden, which outlined cooperation in six domains—from security to sustainability.
In stark contrast, the 2025 summit under President Trump narrowed the scope to three bullet-pointed economic priorities:
-
Enhancing the commercial environment through regulatory reform
-
Boosting trade, investment, and access to critical minerals
-
Accelerating the development of the Trans-Caspian trade corridor
Gone are the once-prominent discussions on climate adaptation, regional water security, and Afghan stabilization. The phrase “shared challenges” appeared six times in the 2023 declaration; it’s entirely absent in 2025’s joint statements.
From Multilateralism to Bilateralism
Perhaps the most telling aspect of the summit is not what was included, but what was excluded. Alongside the main C5+1 statements, the US released five country-specific bilateral fact sheets—a format shift that underlines the pivot toward “5 C1+1s.”
These fact sheets demonstrate clear American intent: maximize economic gains by targeting countries that offer the most strategic or commercial potential. The difference in tone and depth across the documents is striking.
-
Kazakhstan and Uzbekistan emerge as Washington’s preferred partners. Each country’s sheet highlights major business wins for the US, such as improved market access and support for American exporters.
-
Tajikistan and Kyrgyzstan are given more modest treatment, although still framed around benefits to US companies and workers.
-
Turkmenistan, a long-standing enigma in the region, is treated cautiously. Its fact sheet offers no firm deals, only promises to “consider” engagement in key sectors like critical minerals and gas pipeline development.
Notably, Turkmenistan remains under a partial US travel ban affecting students and tourists—a topic not addressed during the summit.
The Rise of the B5+1 and TRIPP
Supporting this economic turn is the promotion of B5+1, the business counterpart to the diplomatic C5+1, intended to increase private sector cooperation. Areas of interest now include:
-
Civil nuclear technology
-
Hydropower and energy infrastructure
-
IT, e-commerce, tourism, and agriculture
Another key initiative is the Trump Route for International Peace and Prosperity (TRIPP)—a new trade and infrastructure corridor meant to reinforce US regional presence and offer alternatives to China’s Belt and Road Initiative.
A Calculated Trade-Off
What’s emerging is a vision of diplomacy driven by quantifiable results—deals, investments, trade figures—rather than long-term regional problem-solving. The US now calculates success through export growth and access to critical minerals, sidelining deeper issues of regional integration, political reform, and environmental risk.
While some may see this shift as pragmatic, it carries risks. The original C5+1 offered a rare forum for multilateral dialogue on sensitive issues like water sharing and border disputes. Without such a mechanism, there’s concern that unresolved tensions may fester beneath the surface of economic optimism.
Conclusion: A New US-Central Asia Order?
This policy recalibration raises fundamental questions: Is economic pragmatism enough to sustain meaningful influence in Central Asia? Can bilateral deal-making replace the value of regional diplomacy?
Time will reveal whether Washington’s pivot produces long-term strategic value—or simply short-term economic returns.
