Afghan Authorities Accelerate Push for Road and Rail Projects

As the Taliban government pursues an assertive policy to enhance Afghanistan’s logistical infrastructure, interest in the country’s role as a southern transit hub is gaining momentum across West Asia, facilitating the joint implementation of a wide range of new road and rail projects. Leading the charge is Uzbekistan, which has revived its ambitions through the Termez–Mazar-i-Sharif–Kabul–Peshawar railway—better known as the Kabul Corridor—positioning itself at the forefront of regional integration.

Meanwhile, Turkmenistan, backed by Kazakhstan, is advancing a parallel railway initiative through western Afghanistan to secure more direct access to Pakistan’s seaports. In a symbolic move, the foundation for the 22-kilometre Torghundi-Sanobar railway line was laid in September 2024, making a significant step towards reshaping regional connectivity.

The growing engagement between the Central Asian republics and Kabul in the development of transport infrastructure reflects a shared ambition to diversify foreign trade routes and establish more efficient supply chains to access the vast South Asian market. Alongside ongoing projects involving Uzbekistan, Turkmenistan, and Kazakhstan, Afghan authorities have announced plans to construct the Mazar-i-Sharif–Herat–Kandahar railway. This line has the potential to become the shortest trade route between India and Russia, enabling New Delhi to build transport links with Afghanistan and Central Asia while bypassing Pakistan.

Even Iran, which remains the primary conduit linking Central Asia to the warm waters of the Indian Ocean, and, by extension, to global trade, is seeking stronger transport links with Afghanistan. Tehran is planning to launch two railway connections to Afghanistan simultaneously: the Khaf–Herat line in the north and the Zahedan–Zaranj line in the south-west. The railway from Khaf to Herat is nearly complete, and the Taliban intend to extend it to Mazar-i-Sharif, a key Afghan trade hub already connected to the Uzbek-built Hairatan–Mazar-i-Sharif railway (launched in 2011) and the planned Kabul Corridor. Integrating these routes could eventually allow Iran to reach the Wakhan Valley in Afghanistan’s Badakhshan province, which is the narrow strip of land separating Afghanistan from China.

Notably, during a Taliban delegation’s two-day visit to Tashkent in February 2025, Uzbek and Afghan authorities agreed to jointly implement the Mazar-i-Sharif-Herat railway route. According to the Afghan Deputy Prime Minister for Economic Affairs, Mullah Abdul Ghani Baradar Akhund, this project would expand Tashkent’s trade with South Asia, Iran, and China, reinforcing the idea that Tehran could utilise the Kabul Corridor to reach the borders of China’s Xinjiang region. Another potential route could see the Zahedan-Zaranj railway extended to Kandahar and Kabul with its subsequent link to the Wakhan Corridor.

In 2020, Iran began constructing the Chabahar–Zahedan railway line, with plans to extend it to Zaranj in Afghanistan’s border province of Nimroz and further onward to Dilaram and Kandahar. Engineering surveys have already been conducted on the Afghan side for the Zaranj–Kandahar railway, which could offer Tehran an alternative access route to Afghanistan beyond the Herat Road—bringing it one step closer to creating a new overland trade route to China.

Nevertheless, the prospect of reviving the Wakhan Corridor— an outcome eagerly anticipated by Tehran—remains uncertain. In 2024, Afghanistan’s Ministry of Rural Rehabilitation and Development announced the completion of gravel laying on a 50-kilometre stretch of the road. However, substantial investments are needed to turn the ancient route into a viable commercial transit point. The Taliban are striving for help from China, although Beijing has so far adopted a cautious, wait-and-see approach and is in no rush to open its arms to Afghanistan.

Despite this limited progress, Tehran appears unlikely to back down, particularly as it pursues other ambitious projects. One of these is the proposed Iran–Afghanistan–Tajikistan–Kyrgyzstan–China railway corridor, also known as the Five Nation Road.

Its initial section will be the Khaf-Herat railway, scheduled to begin full operations later this year. The route would continue through Sheberghan, Mazar-i-Sharif, Khulm, and Kunduz, ultimately reaching the Tajik border at the Sherkhan Bandar crossing. It would then stretch eastwards across Central Asia to Kashgar in western China, spanning an estimated 2,000 kilometres. In this context, the Taliban’s proposed Mazar-i-Sharif–Herat railway becomes a strategic segment of a broader transit route from Iran to China.

The creation of a Five Nation Transit Corridor could also benefit Turkmenistan, which has long pursued a railway link to Tajikistan via Afghanistan through the TAT project. This initiative emerged in 2013 amid rising tensions between Tashkent and Dushanbe over transit routes and the desire to bypass Uzbekistan.

Turkmenistan completed the first stage of the TAT railway in 2016, spanning from Atamurat (Kerki) through Ymamnazar to Akina. The Akina–Andkhoy segment followed in early 2021. However, the Taliban’s return to power in summer 2021 brought work to a halt, as regional actors reassessed the group’s stance on cross-border infrastructure and foreign engagement. Yet contrary to initial concerns, the new Afghan leadership has shown a pragmatic approach to regional connectivity.

In February 2025, Afghanistan and Turkmenistan agreed to carry out survey and design work for the 55-kilometre Andkhoy–Sheberghan railway line, a project first announced by the Taliban in 2024. Meanwhile, in July 2024, Tajikistan’s Ministry of Transport and the Korea International Cooperation Agency signed a protocol to develop a feasibility study for a 51-kilometre Jaloliddini-Balkhi–Panji Poyon railway, linking Tajikistan to the Afghan border. Both developments indicate a resumption of the TAT project, which could raise concerns in Uzbekistan, given its longstanding role as a key transit country for several of its neighbours’ access to global markets.

The development of trans-Afghan logistics infrastructure is also of growing interest to Russia, which sees the new corridors as a means of extending its flagship International North–South Transport Corridor (INSTC) to Pakistan.

A clear indication of this was the visit of a Russian delegation led by Security Council Secretary Sergei Shoigu to Kabul on 25 November 2024, during which the construction of the Trans-Afghan Railway was discussed. Following talks with the Taliban, Russian Deputy Prime Minister Alexei Overchuk stated that the Russian Federation considers this project as an integral component of the INSTC.

The Russian Ministry of Transport later announced that it would collaborate with Uzbekistan to prepare a feasibility study for a railway through Afghanistan, based on two agreed routes: Mazar-i-Sharif–Herat–Dilaram–Kandahar–Chaman and Termez–Naibabad–Logar–Kharlachi. But this announcement was not confirmed by Uzbekistan Railways.

Russian involvement in constructing both the western and eastern Afghan railway routes—starting from the borders with Turkmenistan and Uzbekistan, respectively—would allow Ashgabat and Tashkent to secure a share of cargo flows between Northern Eurasia to South Asia. Increased competition along these routes is likely to drive down the cost of transit transport over time.

The opening of new trade routes through Afghanistan presents significant opportunities for realising Central Asia’s economic and transport-transit potential. Several key factors should be considered when assessing further developments in this area.

One consideration is the potential reorientation of Uzbekistan towards the western Trans-Afghan railway route. The relative cost-effectiveness of the Kandahar Corridor, compared to the railway via Kabul, could serve as a catalyst for such a shift. Although the Mazar-i-Sharif-Herat-Kandahar-Chaman route (1,468 km) is longer than the Kabul Corridor (647 km), it offers advantages in terms of terrain and security. Additionally, the route can branch towards Iran through the border province of Nimroz in south-western Afghanistan, providing a valuable strategic link for future transport corridors.

Another important factor is the growing security risks in Pakistan, coupled with increasing tensions in Afghan-Pakistani relations. These dynamics may prompt Tashkent and its external partners to reconsider their preferences on the trans-Afghan track, favouring the Kandahar Corridor instead. In this context, prioritising a transit route that connects to the southern regions of Pakistan—those closest to the ocean—would be more appropriate.

Given the growing significance of Afghan transit in transregional logistics, Central Asian countries will need to balance the interests of all stakeholders to prevent the emergence of intensified geopolitical rivalries along these evolving trade corridors. Harmonisation of the trans-Afghan routes currently under development appears to be both the most likely and most favourable scenario for the future. In such a case, the key stakeholders, particularly Uzbekistan, Turkmenistan and Kazakhstan, could pool their resources to establish a unified transregional railway corridor through Afghanistan.

This collaborative approach would enhance the prospects for attracting external investment and accelerating project implementation. Moreover, a consolidated approach is vital for strengthening the region's role in shaping the emerging architecture of trans-Afghan connectivity. If done successfully, Afghanistan could gain a genuine opportunity to position itself as a new transit hub at the heart of Eurasia.

GCC and Central Asia Want More Trade, But Connectivity Remains a Hurdle

Over the course of the past five years, the six countries of the Gulf Cooperation Council (GCC) and the five republics of Central Asia have taken several important steps to expand their economic and diplomatic relations. In addition to the advancement of bilateral relations among members of these two blocs, efforts have also been made at the regional level involving multiple countries from both sides. This includes several gatherings at the ministerial level, as well as the 2023 GCC-C5 summit that convened the six GCC and five Central Asian countries—Kyrgyzstan, Kazakhstan, Uzbekistan, Tajikistan, and Turkmenistan—in Saudi Arabia. The high-level summit resulted in a joint statement on the framework for economic relations. Preparations are currently underway for a follow-up summit in May 2025 in Samarkand.

The volume of trade between the two blocs is currently small. According to data compiled by the World Bank, the share of GCC countries in total exports of goods by Central Asian countries was only 0.8 percent in 2022. The ratio was even smaller for Central Asia’s largest economy, Kazakhstan, which exported only $462 million to GCC countries. This amounted to 0.55 percent of its $83.5 billion total goods exports in that year.

Trade relations are expected to expand from this low base if the forthcoming summit in Samarkand is fruitful. Not only is the GCC interested in the minerals, metals, and agricultural commodities that Central Asia can offer, but both regions are moving toward economic diversification. This will increase the range of manufactured and semi-processed goods that they can exchange.

While both sides have expressed a strong desire to expand their investment and trade relations in many sectors, transit routes and transportation costs pose important considerations for their respective political leaders and business communities. In their July 2023 summit, the leaders of GCC and Central Asia were already mindful of this issue. Connectivity was addressed in the Article 12 of the Summit’s Joint Statement: “The leaders stressed the importance of developing connected transportation routes between the two regions, building strong logistical and commercial networks, and developing effective systems that contribute to the exchange of products.”

The transport networks between GCC and Central Asia cross through several countries. Three distinct transport routes can potentially provide land connectivity between the regions in the coming years. These are the North-South Transport Corridor (NSTC) that runs mainly through Iran, the Development Road Project (DRP) that runs through Iraq, and the Trans-Afghan Corridor. Each of these multi-modal routes presents its own unique opportunities and challenges.

Firstly, it is important to consider the NSTC route through Iran. Currently the Central Asian countries have access to highway and rail transit through Iran to the Persian Gulf and the Gulf of Oman. With cooperation of Iran, Russia, and several Central Asian countries the rail connectivity has been operational since 2016. The trans-Iranian Railway connects the Sarakhs railway station on Iran-Turkmenistan border to the Bandar Abbas port on the Persian Gulf and this route is already in use by the Central Asian countries. 

Highway transit for cars and trucks is also operational; Iran’s network of roads and highways connects the Iran-Turkmenistan border crossings to several seaports in the Persian Gulf, from which containers can be transported to GCC countries by ship. The railroad transit will expand further with the completion of the Sarakhs-Chabahar railway line. Nearly two thirds of this route is already complete. The only remaining piece is the Chabahar-Zahedan segment which is currently under construction, though progress is slow due to economic sanctions. Iranian government officials expect this project to be completed by late 2025.  

These transit routes through Iran are safe,  offering the shortest and most cost-effective routes for GCC-CA connectivity. However, many GCC economic operators will avoid using this route in compliance with the U.S. economic sanctions against Iran. GCC countries have demonstrated high compliance with the U.S. sanctions against Iran because of their heavy reliance on American security and military protection; this cooperation is likely to continue in the future. 

Another transit route that can be used for trade between the GCC and Central Asia is the proposed north-south Development Road Project, which will, using rail and highway, connect Iraq’s Faw port at the tip of the Persian Gulf to Turkey’s broader transport network. This project is currently in its final planning stage according to Iraq’s Transport Minister, Razzaq Muhibis Al-Saadawi. After the recent improvement of diplomatic relations between Iraq and GCC countries, Qatar and the UAE have expressed an interest in providing additional financial support, assisting Iraq and Turkey in the endeavor. 

The DRP offers a significantly longer transit route compared to the Iran option. Additionally, it requires greater international coordination, as it passes through multiple countries—Iraq, Turkey, Georgia, and Azerbaijan—before requiring sea transport across the Caspian Sea to reach either Turkmenistan or Kazakhstan for connections to Central Asia. The Turkey-Turkmenistan segment, which is part of the Belt and Road Initiative’s middle corridor between Asia and Europe, is already operational. If Azerbaijan and Turkey can convince Armenia to provide them with a transit corridor, this route will become shorter and more cost efficient, yet still less economical than the Iran option. 

The DRP also faces several geopolitical and governance challenges. Kurdish militias that are in war with Turkey operate in the mountainous regions of Northern Iraq, near the Turkish border, posing a security risk to the road both during its construction and after completion. The Iraqi government’s opposition to the participation of the Kurdish Regional Government (KRG) poses another obstacle to the viability of this project as disagreements between Baghdad and KRG can lead to more disruption. 

Another challenge is the many governance issues in Iraq’s fragmented government structure, which has reduced the government’s efficacy and ability to implement long-term plans. Fortunately, Iraq’s political system has become more stable in recent years, contributing to better conditions for the implementation of the DRP. A recent security agreement between Turkey and Iraq might also reduce the security risks in northern Iraq.

A third land transit route between the GCC and Central Asia is the Trans-Afghan option, which will offer rail transit from Uzbekistan to Pakistan’s Karachi and Gwadar seaports on the Arabian Sea through Afghanistan. Cargo would be able to be transported from these ports to various GCC destinations in the Persian Gulf by ship. The Trans-Afghan Corridor has received support from Kazakhstan and Uzbekistan as the primary Central Asian stakeholders. Uzbekistan has also approached Qatar and the UAE for financial investment in this project, which is estimated to cost $7 billion.

Under the previous Afghan government, the Taliban posed a security risk to the Trans-Afghan Corridor. Now, in a turn of events, the Taliban-led government is a strong supporter, engaging in active negotiations with all stakeholders to expedite the project. In 2024, Afghanistan signed an agreement with Uzbekistan and the UAE to launch a feasibility study for the project. Pakistan is also lobbying the Central Asian countries, Qatar, and the UAE for support. 

Another important tailwind behind this project is the support of several other countries, including Russia and Belarus, which are also interested in development of the Afghan route. For Russia, which faces sanctions and security risks along its Baltic and Mediterranean transit routes, the Trans-Afghan Corridor will serve as an additional branch of the already operational NSTC route through Iran. In addition to the Uzbek option, Russia is also advancing an alternative branch of the Trans-Afghan railway via the Turkmenistan-Afghanistan border, further expanding the capacity of transit routes through Afghanistan.

The transit corridor competition that is currently underway between Iraq, Iran, and Afghanistan will increase the land connectivity options among the GCC and Central Asian countries in the coming years, reducing exposure to the risk factors in any single country that lies between the two blocs. While at present the only operational route is via Iran, it is encumbered by sanctions risks. The completion of the DRP and the Trans-Afghan Corridor will provide valuable alternatives despite being lengthier and hence more expensive. Their development will be reassuring to both the GCC countries and the Central Asian countries as they seek to boost trade ties as part of a process of West Asian integration.
