Summary of Key Points
Data from the Shanghai Customs in May shows that for the first time, ASEAN surpassed the European Union (EU) as Shanghai's largest trading partner by a narrow margin in a single month, with a difference of approximately 540 million yuan. This is not an accident but the result of ASEAN's continuous efforts over more than a decade. The EU's trade volume with Shanghai was nearly twice that of ASEAN in 2014; by 2020, ASEAN had become Shanghai's second-largest trading partner, and in May 2026, it finally surpassed the EU on a monthly basis. Behind this change are the benefits of the RCEP (Regional Comprehensive Economic Partnership) agreement, the upgrading of free trade zones, and the restructuring of global supply chains. However, this monthly reversal does not mean that the annual trade pattern has completely changed (the EU remains Shanghai's largest trading partner for the whole year 2025). Moreover, Shanghai still relies heavily on Europe and the United States, reflecting the trend towards diversification in China's foreign trade.
I. The Historical Moment of the Monthly Overturn: A Difference of 540 Million Yuan
In May this year, Shanghai's imports and exports with ASEAN amounted to 70.11 billion yuan, a year-on-year increase of 26.4%, while those with the EU were 69.57 billion yuan, an increase of only 2.6%. ASEAN surpassed the EU for the first time by a margin of 540 million yuan—roughly equivalent to the annual revenue of a medium-sized manufacturing company. Vietnam stood out particularly, with Shanghai's import and export volume with Vietnam increasing by 110.4%, making it the "growth engine" within the ASEAN region. The significance of these figures lies not in the numbers themselves but in the fact that they have broken the long-standing dominance of the EU in Shanghai's foreign trade, representing a culmination of trends over more than a decade.
II. A Decade of Catch-up: From "EU Twice as Large as ASEAN" to "Overpass"
ASEAN's rise has not been immediate but follows a clear trajectory of catching up:
- 2014: The EU's trade volume was nearly twice that of ASEAN (637.9 billion yuan vs 330.4 billion yuan), with ASEAN ranking only as Shanghai's fourth-largest trading partner (behind the EU, the United States, and Japan).
- 2015: ASEAN surpassed Japan to become third.
- 2020: ASEAN surpassed the United States to become second, although the EU still led by more than 210 billion yuan.
- 2024: The EU's trade volume decreased by 4.8% year-on-year, while ASEAN's increased by 6.9%, significantly narrowing the gap.
- May 2026: ASEAN finally surpassed the EU on a monthly basis.
Over these ten years, ASEAN has gradually closed the gap until this recent milestone.
III. The Reasons Behind the Overpass: Policies Facilitating Trade and Supply Chain Realignments
There are several key reasons why ASEAN was able to catch up with the EU:
1. Benefits of RCEP and Free Trade Zones: The RCEP and the upgraded China-ASEAN Free Trade Zone have made doing business in ASEAN more profitable for companies, with reduced tariffs and simplified procedures. For example, many goods exported from Shanghai to ASEAN are exempt from tariffs, lowering costs and increasing trade volumes.
2. Tariffs between China and the US Driving Supply Chain Realignments: Tariff barriers between China and the US have prompted many companies to move parts of their production to ASEAN (such as Vietnam and Thailand) before exporting to the US. This has increased trade volume between Shanghai and ASEAN; for instance, Shanghai ships components to Vietnam for assembly and then imports finished products.
3. The Vitality of the ASEAN Market: ASEAN countries are experiencing rapid economic growth, with increasing demand for Chinese goods (such as machinery and raw materials). As a leading city in the Yangtze River Delta, Shanghai benefits from this growing market.
IV. Beyond the Highlights: Monthly Data Does Not Equal Annual Trends; Shanghai Still Relys on Europe and the US
While this monthly reversal is significant, there are two important considerations:
- Monthly data does not reflect annual trends: The EU will still be Shanghai's largest trading partner for the whole year 2025, so this victory is only temporary. Whether ASEAN can maintain its lead throughout the year remains to be seen.
- Shanghai's Heavy Dependence on Europe and the US: Although ASEAN surpassed the EU as China's largest trading partner nationwide in 2020, it took until May 2026 for Shanghai to do so on a monthly basis, indicating that Shanghai's foreign trade is more reliant on these markets than the national average.
Nevertheless, this change reflects a broader trend in China's foreign trade: moving away from a focus on Europe and the US towards diversification, with ASEAN becoming an important new direction. As Shanghai is a key hub for China's foreign trade, this development suggests that the trade patterns of other cities may also adjust in the future.
Conclusion
ASEAN's emergence as Shanghai's largest trading partner for a single month is the result of combined efforts by policies, market dynamics, and supply chains, reflecting the diversification of China's foreign trade. Although this is just a monthly statistic, it indicates that significant changes are underway in Shanghai's trade landscape, with ASEAN likely playing an increasingly important role in the future.
