Central Asia Railway Could Cost Up to $9 Billion, Former Kumtor Executive Warns
Tengiz Bolturuk's cost estimate arrives as Kazakhstan's panda bond programme accelerates and Chinese capital flows into Central Asia's energy, mining and infrastructure at a quickening pace.
Former Kumtor Gold Company CEO Tengiz Bolturuk predicted recently that a proposed China-Central Asia railway project could cost up to $9 billion, oilprice.com reported on Wednesday (2026-08-12). No baseline estimate was cited for comparison, but $9 billion would rank among the largest single infrastructure outlays yet contemplated for a region whose governments are still assembling the financing capacity to match the pace of Chinese investment.7
In parallel, Kazakhstan is preparing a second round of sovereign panda bonds targeting roughly $500 million. Samruk-Kazyna, the sovereign wealth fund, issued Central Asia's first-ever panda bonds in April 2026; the sovereign itself then placed a 3.4 billion yuan tranche (worth more than $500 million) in May 2026, oilprice.com reported Wednesday (2026-08-12). A second sovereign round would mark the third panda bond transaction in under four months.7
Three transactions in that span indicate that yuan-denominated sovereign debt is becoming a routine financing instrument in Astana. The accelerating pace consolidates Kazakhstan's access to Chinese domestic capital markets at a moment when cost estimates for the region's largest proposed infrastructure project are moving upward.7
Chinese commercial investment is expanding across the broader region in the same period. Zhongjin Guantai Industrial Development Co. wants to put $2 billion into Uzbekistan's mining sector, $1 billion into energy projects, and between $300 million and $500 million into infrastructure and tourism, oilprice.com reported in late June 2026 (2026-06-23).4
Uzbekistan is building the power capacity to absorb capital on that scale. Authorities plan to increase electricity generation from 82 billion kilowatt-hours to more than 120 billion kilowatt-hours within five years, making the power sector one of the country's largest investment targets, finance.yahoo.com reported in July 2026 (2026-07-02).5
Nuclear cooperation between Kazakhstan and China is formalising. Officials signed a protocol in mid-June 2026 (2026-06-17) defining future cooperation in civil nuclear energy, following the inaugural meeting of the Kazakhstan-China Joint Working Group attended by Wang Hongzhi, the head of China's National Energy Administration. Russia's Rosatom has separately agreed to build Kazakhstan's first nuclear power station, estimated at $16.5 billion, with construction scheduled to begin in 2027, according to reporting from late May 2026 (2026-05-29).3,4,1
The OECD set the region's infrastructure challenge in wider context in a June 2026 (2026-06-16) report: Central and Southeast Asia face an annual financing shortfall of more than $217 billion, with investment needs running at 5 to 7 percent of GDP annually. The additional cost of climate-resilient construction averages around 1 percent of GDP, the report found, suggesting mobilising capital of any kind remains the binding problem.2
Soft power is folded into Beijing's Central Asia strategy alongside hard capital. Uzbekistan and China launched the joint hyperspectral satellite Samarkand-2028 to support agriculture and environmental monitoring applications, oilprice.com reported Wednesday (2026-08-12). Washington is also present in the region: the U.S. struck an agreement with Uzbekistan in mid-February 2026 on access to critical minerals, adding a competing interest to Chinese commercial advances.7,6
Kazakhstan's government has not publicly confirmed or disputed Bolturuk's $9 billion figure, leaving it to circulate without an official position as the third panda bond round approaches. A railway at that cost would absorb a significant portion of the financing capacity the region is assembling, and the Kazakh government's response to that estimate is the signal investors in Central Asian sovereign credit will watch most closely.7
