Summary of Key Points
This news article focuses on the trade changes between China and Iran over the past decade: overall, there has been a fluctuating downward trend. Trade reached its peak in 2017, only to decline due to US sanctions, the pandemic, and regional conflicts. The trade structure between the two countries is highly complementary (China imports resources from Iran and exports manufactured goods). Provinces along China's southeastern coast are the main drivers of trade. Although international tensions affect bilateral trade, their impact on China's overall economy and energy security is limited. The development of Sino-Iranian trade has always been closely tied to international situations, especially US-Iran relations, and friendly cooperation is expected to continue in the future.
Detailed Analysis
1. The Ups and Downs of Sino-Iranian Trade Over the Past Decade
Sino-Iranian trade has been highly volatile: it peaked in 2017 as Iran sought to diversify its partners after concerns about European and American reliability, leading to a surge in demand. From 2018 to 2019, China imported more from Iran than it exported (due to US sanctions on Iranian oil). The pandemic caused a decline in trade volumes in 2020, but there was a slight rebound in 2021-2022. In 2023, new US sanctions were imposed, such as restrictions on drone parts and energy shipping, resulting in trade falling to just over $13 billion. In 2025, US-Israeli actions against Iran led to the suspension of many Chinese-funded projects, causing trade to plummet to $9.963 billion, a year-on-year decrease of 25.6%.
In short, whenever the US takes action or regional conflicts arise, Sino-Iranian trade is affected, but Iran continues to rely on China as a partner.
2. What Is Being Traded?
- What Does China Buy from Iran? Mainly resources: crude oil (45% of imports), plastics, and mineral sands (accounting for 82% of total imports), along with some specialty agricultural products. This indicates that Iran is selling raw materials to China.
- What Does China Sell to Iran? Primarily manufactured goods: machinery, electrical equipment, and auto parts (60% of exports), as well as chemicals and steel. Western sanctions on Iran have created a demand for Chinese-made components and machinery, which Iran lacks.
This trade pattern has remained stable over the past eight years, reflecting the mutual dependence between the two countries: China needs raw materials, while Iran requires industrial products.
3. Who Is Driving Sino-Iranian Trade?
- Export Drivers: Provinces along China's southeastern coast, such as the Yangtze River Delta (Zhejiang, Shanghai) and Pearl River Delta (Guangdong), play a key role. These regions have numerous factories capable of producing the goods needed by Iran, and maritime transportation is cost-effective for large shipments. Although the "Belt and Road" initiative provides alternative routes in the west, land transport is more expensive and not as reliable.
- Import Drivers: The same provinces are leading imports, with Zhejiang and Shanghai exceeding $10 billion in imports in 2025. Interestingly, the stricter US sanctions have led to a larger trade surplus for China, demonstrating China's resilience in export capacity.
4. Are Conflicts and Sanctions a Major Impact?
Despite the decline in trade volumes, the impact on China's economy is minimal:
- Energy Security: China has multiple sources of crude oil imports (Saudi Arabia, Russia, Brazil), and its strategic oil reserves ensure it can withstand disruptions from the Middle East.
- Trade Volume: Sino-Iranian trade accounts for just 0.02% of China's total foreign trade volume of $6.67 trillion in 2025. Local fluctuations are unlikely to significantly affect China's overall economy.
5. Seventy Years of Dynamics: Sino-Iranian Trade and International Relations
Iran's relations with the West have been volatile, ranging from pro-Western to outright hostility, including the Iran-Iraq War and ongoing tensions. Sino-Iranian trade has fluctuated accordingly:
- 2015: The Iran nuclear deal was reached, and US sanctions were lifted, leading to a period of growth in trade.
- 2018: Trump withdrew from the deal, re-imposing sanctions, which hit trade.
- 2020: The killing of an Iranian general by US forces nearly led to military conflict between the two countries.
- 2025: US-Israeli airstrikes on Iran further weakened trade.
However, Sino-Iranian trade has shown resilience, as both countries benefit from mutual cooperation. This relationship is likely to continue despite ongoing geopolitical tensions.
Conclusion
Sino-Iranian trade is based on mutual needs and is resilient to external influences. Although it experiences fluctuations due to international events, its impact on China's economy is minimal. The two countries will likely maintain their friendly trade relations in the future.
