Washington Shifts C5+1 From Diplomacy to Deals
On November 6, 2025, Washington hosted the C5+1 summit, bringing U.S. President Donald Trump together with the leaders of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The tone shifted from broad diplomacy to deliverable transactions, with officials emphasizing cooperation on critical raw materials. The timing signified a broader shift in supply chains away from China and Russia, and the discussion moved from general diplomacy to transactions that can be tracked and delivered.
The private-sector track also accelerated. The B5+1 (“B” for “business”) platform is meant to carry follow-through on minerals, processing, logistics, and services. It complements state-to-state commitments by putting contract-ready work streams and policy dialogue in the same frame. Verification is simple: match U.S. and host-government readouts with company filings and ministry communiqués issued after the summit. Subsequent notices should specify instruments, values, financing, timelines, and the units responsible.
What Was Signed Versus What Was Signaled
The summit mixed firm orders with preliminary commitments. Uzbekistan Airways converted eight options for the Boeing 787-9 (covered by FAA Type Certificate Data Sheet T00021SE) into a firm order, bringing its total to twenty-two Dreamliners. That flows into the manufacturer’s backlog and starts financing and ground-side preparation. Tajikistan’s Somon Air announced up to four 787-9s and ten 737 MAX; that signals intent, with binding contracts and financing to follow. Engine families for the 787-9 are Rolls-Royce Trent 1000 TEN and GE Genx-1B, setting maintenance and training paths. Air Astana said it had selected up to fifteen 787-9s. Slot allocation and financing are next, along with sale-and-leaseback or operating-lease decisions.
A parallel commercial package aimed to show that U.S.–Central Asia ties can move on a near-term clock, framed publicly through the Department of Commerce’s announced “C5+1 Deal Zone,” earmarked at “over $25 billion.” Rare earths and related inputs sat at the center of the talks. Aviation and other signings were presented as tangible outcomes. The substance rests with the underlying company agreements and national approvals, although the packaging usefully aggregates a single narrative for public consumption.
Minerals were cast as the strategic core, even though many projects remain in the early stages. Public readouts emphasized supply-chain resilience and competition with China and Russia. For shipments into the European Union, the bottleneck remains the processing limits set by the EU Critical Raw Materials Act. Customs classification uses the Harmonized System (HS), a universal tariff code maintained by the World Customs Organization (WCO): tungsten falls under HS 8101, while rare-earth metals and their compounds are under HS 2805 and HS 2846. Bankability likewise depends on recognized industry disclosure rules for reporting mineral resources, which require standardized geology, sampling, and reserve estimates before serious financing proceeds. Wire services likewise underscored rare earths and closer cooperation along the value chain.
Country Outcomes
Kazakhstan. The most tangible non-aviation item was a tungsten venture at Northern Katpar and Upper Kairakty, with an indicated project scope of around $1.1 billion. A Letter of Interest (LOI) from the U.S. Export–Import Bank (EXIM) suggests a figure near $900 million on a 70/30 structure with the state company Tau-Ken Samruk. An EXIM LOI is indicative and non-binding; it enables execution of due diligence and agreement on preliminary terms of reference. On aviation, Air Astana’s 787-9 selection sets the stage for a binding order and expanded long-haul range from Almaty and Astana. Media placed total agreements above $17 billion across all sectors combined.
Uzbekistan and Tajikistan. Tashkent’s new 787-9 firm order positions the carrier for broader intercontinental service once delivery and financing schedules are set. Wide-body induction will require ETOPS (Extended Operations) 180 procedures, dispatcher training, and simulator time. Uzbekistan also publicized agreements on rare earths with Denali Exploration Group and ReElement Technologies, plus an industrial pact with Flowserve on pumping stations. Credit support features in the road map, with EXIM meetings linking aircraft finance to other projects. Somon Air’s plan—up to four 787-9s and ten 737 MAX—would add its first wide-bodies and demands training, maintenance, and airport readiness before long-haul services.
Kyrgyzstan and Turkmenistan. Bishkek emphasized hydropower upgrades, transport, and IT development. These fit the country’s energy mix and grid goals, though new financing tools were not unveiled in Washington. Pre-summit reporting on the Kambar-Ata-1 (1,860 MW) project illustrates the scale of hydro financing under consideration by European partners. The project hints at the likely multi-lender packages with export credit and international financial institution participation. Turkmenistan, for its part, confirmed presidential participation; however, no new bilateral instruments were published around the event.
Financing, Rules, and Execution
Early financing signals and front-end preparation move airlines and mining sponsors from headlines to funded work. An EXIM LOI can make long-term debt feasible and let buyers shift to preliminary term sheets and diligence. The U.S. Development Finance Corporation (DFC) can fund feasibility and front-end studies, from metallurgical flow-sheets in mining to Level-D simulators in aviation. All this will embed new rule-sets and standard procedures in the region.
The Commercial Law Development Program is a U.S. Department of Commerce initiative that helps partner governments improve commercial laws and procurement so projects can be bid once and disputes contained. In practice, many contracts use materials from the FIDIC, a nonprofit group that publishes simple, standard contract templates for construction projects worldwide. Sanctions and export controls—for example, from the U.S. Export Administration Regulations—then govern parts, inputs, payments, and licenses channeling how components move and how payments clear.
Logistics will also decide whether the agreements are implemented. Middle Corridor frictions include port handling, vessel scheduling on the Caspian, and rail interoperability. Broader use of the CIM/SMGS electronic rail consignment note, which is a single digital waybill accepted across Europe and Central Asia, and more regular roll-on/roll-off ferry schedules on the Caspian would ease near-term bottlenecks. The EBRD and the EU’s Trans-European Transport Network adds customs coordination and digital documentation to the to-do list. To retain more value, embed minerals processing and aviation training and maintenance capacity in project finance from the start, not as add-ons.
Connecting Networks, Expanding Options
The summit points away from geopolitical bloc alignments and toward a multiplex Central Asian order of overlapping rule systems and multiple pathways for cooperation. Energy standards, aviation certification, export credit, sanctions compliance, customs, and data regimes operate as partially independent networks. Influence will accrue to actors who braid these networks on concrete projects and keep sequencing coherent.
Standards and finance are the main levers here: specifications determine what can be bought and maintained, while credit decides who can buy and when. Pairing more than one credible source of credit with more than one standards path strengthens the working network that interlinks Central Asian governments, firms, lenders, and corridor operators. Their practical task is to build parallel channels that are usable in real time.
Taken together, the week’s actions aim to shift Central Asia’s external ties from reliance on a single rule bundle toward managed interdependence. Small-group formats can convert one-off deals into routines while standardizing procurement procedures and regularizing dispute resolution.
When such nodes interconnect across corridors, they add redundancy to midstream minerals processing. New supply-chain corridors alone do not suffice. Interoperable paperwork, predictable customs, and cross-recognized certifications are required; otherwise, flows will revert to the inherited legacy routes. The Washington summit matters insofar as it begins to institutionalize those options, widening the geo-economic room for maneuver by the five Central Asian states.
