Department of State readout states the U.S. supports Kazakhstan's regional integration and development and references use of the C5+1 diplomatic platform.
The U.S. Department of State readout of Deputy Secretary Landau’s Feb. 4, 2026 meeting with Kazakhstan’s foreign minister explicitly states: “The United States supports Kazakhstan’s continued regional integration and development, including through the C5+1 diplomatic platform,” and defines C5+1 as the United States plus Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan. The State Department’s C5+1 background page and the Nov. 7, 2025 Joint Statement of Intent on Economic Cooperation further document U.S. engagement through the C5+1 platform to advance regional economic, energy, and security cooperation. Verdict: True — official U.S. government sources directly support the statement and its definition of the C5+1.
