Trump’s New Threat Against Iran Collides With Central Asia’s Economic Interests
U.S. President Donald Trump has threatened economic consequences for any country that continues to provide support to Iran, promising Tehran “Economic Warfare and Isolation on an unprecedented scale.” Washington has not yet announced specific new measures. For Central Asia, the warning comes as economic and transport links with Iran are developing. Kazakhstan is building its own terminal at Iran’s largest port, Tajikistan is discussing fuel purchases and new transport routes, Uzbekistan is trying to protect trade that passes through Iran, and Turkmenistan is expanding transport and energy cooperation with Tehran. Each country has its own reasons for developing these ties, but they share one concern: for landlocked Central Asia, Iran provides one of the few overland routes to the Persian Gulf and the Indian Ocean. Washington’s attempt to tighten Iran’s economic isolation therefore affects not only the region’s relations with Tehran, but also its own plans to diversify trade and transit. None of this means that Central Asian governments are prepared to disregard U.S. sanctions or enter into a political confrontation with Washington on Tehran’s behalf. The threat of secondary restrictions could cause banks, carriers, and private companies to withdraw from individual transactions even without formal decisions by their governments. Trump has not yet explained exactly what instruments he intends to use to enforce the isolation he announced. Kazakhstan Looks to the Persian Gulf Iran intensified its work with Central Asia well before Trump’s latest threat. In mid-June, the Iranian Minister of Roads and Urban Development Farzaneh Sadegh visited Astana. In talks with Kazakhstan’s Deputy Prime Minister Serik Zhumangarin, the two sides noted that bilateral trade had increased by 26.4% in 2025 to $430.2 million. Astana and Tehran now want to raise it to $3 billion, using, among other things, the free trade agreement between Iran and the Eurasian Economic Union, of which Kazakhstan is a member. The plans go beyond trade. Freight traffic along the International North-South Transport Corridor, which links Russia and Central Asia with Iran and Persian Gulf ports, rose by 12% in 2025 to 3.5 million metric tons. Rail freight between Kazakhstan and Iran also increased by 69%. Astana’s main interest lies even farther south. Iran has allowed Kazakhstan to establish its own transport and logistics terminal at Shahid Rajaee in Bandar Abbas, the country’s largest commercial port. On June 28, the two sides signed a Build-Operate-Transfer agreement. It runs for 27 years, with two years allocated for construction and another 25 for operation. Commercial operations are scheduled to begin in the project’s third year. For Kazakhstan, this is more than simply an overseas terminal. Its Foreign Ministry explicitly links the project to opening access for Kazakh cargo to markets in the Persian Gulf, South and Southeast Asia, and East Africa. In July, Foreign Minister Yermek Kosherbayev again reaffirmed Astana’s interest in the project during a visit to Iran. The ministry also cited a 26.4% increase in bilateral trade in 2025 to $430.2 million. Astana is also considering another Iranian port, Chabahar, on the Indian Ocean....
