As Tehran reached the brink of storage saturation and production cuts of up to 1.5 million barrels per day, the crisis in the Strait of Hormuz has compelled the acceleration projects and trade routes that had long remained peripheral. In this context, China and Russia have assumed an increasingly pivotal role in activating the International North-South Transport Corridor (INSTC) and related routes that bypass the US-controlled sea lanes. What was once a theoretical construct explored by researchers, is now reshaping the geography of Eurasian commerce.Given that Iran has launched close to 3,000 drones and missiles at Emirati targets during the current conflict, UAE’s continued engagement with Tehran appears increasingly untenable. Iranian trade with China, which has consistently ranked as its second‑largest supplier after the UAE, is likely to expand further. Reinforcing this shift, Pakistan in late April quietly issued a formal authorisation permitting re‑exports to Iran through its ports and overland routes.A 10,400‑kilometer overland bridge from China to Tehran has become central to this pivot. Staring from from the western China crossing the Khorgos Gateway the train line enters Kazakhstan along the former Soviet train network, moving on Almaty, crossing the critical Arys junction, entering Tashkent, travelling south through Samarkand and Bukhara and finally completing its journey at Iran’s “spiritual capital” Mashhad. Supported by Pakistan’s new transit order via the Karachi-Taftan and Gwadar-Gabd corridors, this route channels crude and petrochemicals toward Central Asia and China.While a single supertanker dwarfs the capacity of a train, the overland route is virtually immune to maritime interdiction. By denominating shipments in Yuan, China has embedded this corridor within its broader Belt and Road routes and ensured an uninterrupted flow of hydrocarbons and strategic goods.Over recent months, Russia and Iran have expanded their Caspian shipping network, transforming it into what officials describe as a ‘sanctions corridor.’ According to The New York Times, roughly two million tons of Russian wheat are now flowing to Iran through the Caspian alone, underscoring the route’s importance for both essential supplies and military logistics. Crucially, this entire supply line bypasses the Strait of Hormuz and the US-led naval cordon, moving instead through waters where American forces have no authority to interdict.Russian trade figures reveal a sharp spike in cargo volumes along these routes, suggesting not a temporary workaround but a deliberate pivot toward the inland sea. Port logs and satellite imagery confirm a steady procession of vessels shuttling between Astrakhan and Bandar Anzali, while ships calling at Iranian hubs such as Amrabad are often observed with tracking signals switched off or delayed. US officials allege that the same pathway is carrying drone components, but unlike in the Persian Gulf, they cannot legally interdict or board ships in the Caspian, where operations are restricted to the five littoral states.Alongside the Caspian, another unexpected lifeline has emerged is the overland logistics corridor stretching 3,000 kilometers across Russia, Kazakhstan, and Turkmenistan, built on Soviet‑era rail infrastructure and entering Iran at the Sarakhs checkpoint. The war has mobilised overland routes that had long remained stalled. On March 27, the Russian Embassy in Tehran released footage of 300 metric tons shipment in large boxes stamped “Russia is With You” delivered at Astara border.Instability around Hormuz has hastened the practical implementation of inland routes, both commercially and strategically. On May 17, 2023, Russian president Vladimir Putin and his Iranian counterpart Ebrahim Raisi oversaw, via video-link an agreement to jointly finance and construct the162‑kilometer Rasht–Astara Railway line. Though modest in scale, this section is a critical link in the North–South international transport corridor, enabling seamless rail communications across its 7,200‑kilometer span.Global energy disruptions have sharpened indications that Moscow and Beijing are edging closer to finalising the long‑anticipated Power of Siberia‑2 pipeline, designed to carry gas from Russia’s Yamal Peninsula to China via Mongolia along a 2,600‑kilometer route. During his April visit to Beijing, Foreign Minister Sergei Lavrov tied the pipeline directly to this geopolitical context, declaring that Russia and China have the “capabilities” to shield themselves from “aggressive adventures that undermine the global economy and the energy sector.”This convergence extends into polar waters, where Russia and China have accelerated cooperation on the Northern Sea Route (NSR), a maritime path that shortens the Asia-Europe voyage by 30-40%, that stretches the Beijing’s Belt and Road Initiative into the Arctic, even as Moscow leverages its Arctic geography to embed itself in global shipping networks. The momentum to integrate the NSR into broader Eurasian strategy, has greatly picked up in the past year complementing the INSTC and Caspian corridors.For global shipping companies, the Hormuz blockade has forced a scramble toward land routes and alternative maritime paths, underscoring the fragility of traditional chokepoints. The activation of INSTC with railroads along the coast, Iran’s overland bridge to China, Russia’s Caspian routes and Siberia‑2 pipeline, and the joint expansion of the Northern Sea Route are not isolated projects but interconnected components of a larger design. They reflect the convergence of Chinese, Russian, and Iranian interests in countering U.S. pressure and ensuring strategic autonomy. From speculative vision these corridors are becoming operational realities, activated by necessity, reinforced by strategic cooperation embedding strategic autonomy at the heart of Eurasian integration.Vaishali Basu Sharma is a strategic and economic affairs analyst.
