After over two decades of discussion, the China-Kyrgyzstan-Uzbekistan (CKU) Railway has entered its active construction phase, with ground-breaking ceremonies held simultaneously in Kashgar (China), Naryn (Kyrgyzstan), and Andijan (Uzbekistan) on May 15, 2026. The 486-kilometer railway represents the first significant new rail corridor in Central Asia in over 30 years and is widely regarded as a geopolitical and economic game-changer for the region's connectivity.
经过二十多年的讨论，中吉乌铁路已进入实质性建设阶段，2026年5月15日在中国喀什、吉尔吉斯斯坦纳伦和乌兹别克斯坦安集延同时举行了奠基仪式。这条486公里的铁路是30多年来中亚首条重大新建铁路走廊，被广泛视为该区域互联互通的地缘政治和经济变革者。

The CKU Railway will follow a route traversing the Torugart Pass (3,752m), the highest point of the Tian Shan range on the China-Kyrgyzstan border:
- Chinese section (Kashgar to Torugart): 165 km — primarily upgrades to existing rail infrastructure at Chinese standard gauge (1,435 mm)
- Kyrgyz section (Torugart to Jalal-Abad): 260 km — the most challenging segment, requiring 48 tunnels totaling 52 km and 86 bridges spanning 21 km, through mountainous terrain with elevations exceeding 3,000m
- Uzbek section (Jalal-Abad to Andijan): 61 km — mostly flat terrain, connecting to Uzbekistan's existing rail network
The track will be built to Chinese standard gauge (1,435 mm) along the entire mainline, with break-of-gauge facilities at a terminal station in Andijan for transfer to the 1,520 mm gauge used by Uzbekistan and the broader Former Soviet Union (FSU) rail network. Total construction cost is estimated at $8.2 billion, with China providing 85% of the financing through preferential loans and the Silk Road Fund.
中吉乌铁路将穿越天山山脉中吉边境海拔最高的吐尔尕特山口（3752米）：
- 中国段（喀什至吐尔尕特）：165公里——主要为现有铁路基础设施的升级改造，采用中国标准轨距（1435毫米）
- 吉尔吉斯段（吐尔尕特至贾拉拉巴德）：260公里——最具挑战性的路段，需要建设48条隧道总长52公里和86座桥梁总长21公里，穿越海拔3000米以上的山区
- 乌兹别克段（贾拉拉巴德至安集延）：61公里——主要为平坦地形，连接乌兹别克斯坦现有铁路网
全线主线将采用中国标准轨距（1435毫米），在安集延的终点站设置轨距转换设施，以切换至乌兹别克斯坦和更广泛的前苏联铁路网使用的1520毫米轨距。总建设成本估计为82亿美元，中国提供85%的融资，通过优惠贷款和丝路基金安排。

| Phase | Segment | Length | Target Completion | Estimated Cost |
|-------|---------|--------|-------------------|----------------|
| 1 | Kashgar–Torugart (upgrade) | 165 km | Late 2027 | $1.5 billion |
| 2 | Torugart–Jalal-Abad (main construction) | 260 km | Late 2030 | $5.2 billion |
| 3 | Jalal-Abad–Andijan + gauge interchange | 61 km | Mid 2028 | $1.5 billion |
The Kyrgyz section, being the most geologically complex, represents the critical path. Tunnel boring has commenced at three portals simultaneously, with China's China Railway Tunnel Group (CRTG) deploying six tunnel boring machines (TBMs) — the first time TBMs of this scale have been used in Central Asian rail construction.
| 阶段 | 路段 | 长度 | 目标完工 | 预估成本 |
|-----|------|------|---------|---------|
| 1 | 喀什–吐尔尕特（升级） | 165公里 | 2027年底 | 15亿美元 |
| 2 | 吐尔尕特–贾拉拉巴德（主体工程） | 260公里 | 2030年底 | 52亿美元 |
| 3 | 贾拉拉巴德–安集延+轨距转换 | 61公里 | 2028年中 | 15亿美元 |
吉尔吉斯段地质最为复杂，是关键控制工程。隧道掘进已同时在三个洞口启动，中国中铁隧道局部署了六台隧道掘进机——这是此类大型TBM首次用于中亚铁路建设。

According to the Asian Development Bank's Central Asia Regional Economic Cooperation (CAREC) assessment:
- Current China-Central Asia rail trade: Approximately 12 million tons annually, primarily traveling through the Alataw Pass (Kazakhstan) — a route that is nearing capacity
- Post-CKU completion (2031+): The CKU corridor is expected to carry 8-12 million tons annually, creating a parallel route that reduces shipping distance from China to Uzbekistan by 900 km and cuts transit time by 7-8 days compared to the current Kazakhstan route
- Cost savings: Estimated $150-200 per ton in logistics cost reduction for China-Uzbekistan trade, and $250-300 per ton for China-Turkmenistan-Iran corridor traffic
For Chinese Xinjiang region specifically, the railway is projected to boost the region's cross-border trade by 35-40% by 2032, positioning Kashgar as a dual-hub along with Horgos for China's westward trade.
据亚洲开发银行中亚区域经济合作（CAREC）评估：
- 当前中国-中亚铁路贸易：每年约1200万吨，主要通过阿拉山口（哈萨克斯坦）运输——该线路已接近饱和
- 中吉乌铁路完工后（2031年以后）：预计每年承载800-1200万吨，形成一条并行路线，中国至乌兹别克斯坦的运输距离缩短900公里，较目前经哈萨克斯坦的路线缩短运输时间7-8天
- 成本节约：中国-乌兹别克斯坦贸易物流成本降低约每吨150-200美元，中国-土库曼斯坦-伊朗走廊运输成本降低每吨250-300美元
对中国新疆地区而言，预计到2032年该铁路将使区域跨境贸易额增长35-40%，将喀什定位为霍尔果斯之外中国向西贸易的第二个枢纽。

- Agricultural exports: Kyrgyz and Uzbek dried fruits, textiles, and fresh produce will gain direct rail access to China's Xinjiang market, with refrigerated container capacity planned at 150,000 TEUs annually
- Mineral resources: Kyrgyzstan's Kumtor gold mine and Uzbekistan's Navoi mining region will benefit from reduced equipment and consumables logistics costs
- Industrial relocation: Uzbekistan's Free Economic Zones (FEZs) in Andijan and Namangan are marketing to Chinese manufacturing firms, offering 10-year tax holidays and direct rail connectivity to Kashgar's comprehensive bonded zone
- 农产品出口：吉尔吉斯和乌兹别克的干果、纺织品和新鲜农产品将获得直达中国新疆市场的铁路通道，规划冷链集装箱运力为每年15万标准箱
- 矿产资源：吉尔吉斯斯坦的库姆托尔金矿和乌兹别克斯坦的纳沃伊矿区将受益于设备和耗材物流成本的降低
- 产业转移：乌兹别克斯坦安集延和纳曼干的自由经济区正向中国制造企业招商，提供10年免税期和直达喀什综合保税区的铁路连接

The CKU Railway carries strategic significance beyond economics. By providing a railway corridor bypassing Kazakhstan — where Russia retains significant influence through the Eurasian Economic Union (EAEU) — the CKU route offers China and Central Asian states an alternative connectivity framework. Uzbekistan's observer status in the EAEU and its active role in the Shanghai Cooperation Organization (SCO) have facilitated the project's approval. Additionally, Kyrgyzstan's parliament ratified a 50-year concession agreement with a China-Uzbekistan joint venture for rail operations, ensuring long-term operational stability.
中吉乌铁路的战略意义超越经济层面。通过提供一条绕过哈萨克斯坦的铁路走廊——俄罗斯通过欧亚经济联盟在哈萨克斯坦保留着重要影响力——中吉乌路线为中国和中亚国家提供了一个替代性的互联互通框架。乌兹别克斯坦在欧亚经济联盟的观察员地位及其在上海合作组织中的积极作用推动了该项目的通过。此外，吉尔吉斯斯坦议会批准了与一家中乌合资企业50年的铁路运营特许权协议，确保了长期运营的稳定性。
