In September 2026, Chinese Vice Minister of Commerce Yan Dong told a press briefing at the State Council Information Office that China-ASEAN trade reached $744.41 billion in the first seven months of 2026, up 24.7 percent year-on-year and accounting for 21.8 percent of China's total foreign trade over the same period. The figures mark another record for the scale of China-ASEAN trade and extend a trend of deepening economic ties between the two sides in recent years. Yan also noted that ASEAN has remained China's largest trading partner for six consecutive years, while China has been ASEAN's largest trading partner for seventeen consecutive years, further cementing a relationship in which each side is the other's top trade partner. That means the mutual top-partner status the two sides established in 2020 has not loosened amid global trade turbulence, but has instead accelerated against the grain, making ASEAN one of the most dynamic growth directions in China's overall foreign trade map.

Historical data show that China-ASEAN trade has been expanding at an accelerating pace. In 2025, bilateral trade between China and ASEAN surpassed $1 trillion for the first time, reaching $1.05 trillion, up 7.4 percent year-on-year -- a milestone in the relationship. Growth has picked up further in 2026: according to China's General Administration of Customs, bilateral trade in the first half of the year reached 4.34 trillion yuan, up 18.2 percent year-on-year, with growth in the second quarter accelerating to roughly 20.2 percent. By the end of July, dollar-denominated trade had reached $744.41 billion, with year-on-year growth widening to 24.7 percent, signaling continued momentum heading into the second half of the year. ASEAN first overtook the European Union to become China's largest trading partner in the first half of 2020, a position it has now held for six straight years. Notably, Guangxi, China's frontline border region facing ASEAN, recorded ASEAN trade of just 248.21 billion yuan in the first seven months, up only 2.5 percent year-on-year -- well below the national average, indicating that this round of trade growth is no longer confined to traditional border-trade channels but increasingly driven by nationwide industrial and supply chains linking up with ASEAN.

The institutional driver behind this deepening relationship is the Upgrade Protocol for Version 3.0 of the China-ASEAN Free Trade Area, signed on October 28, 2025, in Kuala Lumpur, Malaysia. The agreement was signed during the 28th China-ASEAN Summit by Chinese Commerce Minister Wang Wentao and Malaysian Minister of Investment, Trade and Industry Tengku Zafrul Aziz, representing ASEAN, with Chinese Premier Li Qiang and Malaysian Prime Minister Anwar Ibrahim in attendance. The China-ASEAN Free Trade Area dates back to the Framework Agreement on Comprehensive Economic Cooperation signed by the two sides in 2002, was fully implemented in 2010, and was upgraded to Version 2.0 in 2015. The new 3.0 upgrade builds on existing trade-in-goods, trade-in-services and investment cooperation by adding nine new areas: the digital economy, the green economy, supply chain connectivity, standards and technical regulations, sanitary and phytosanitary measures, customs and trade facilitation, competition policy and consumer protection, cooperation on micro, small and medium enterprises, and economic and technical cooperation. The protocol has not yet formally entered into force, as it still requires each party to complete its own domestic ratification procedures. Seven ASEAN member states, including Thailand, have already completed their domestic procedures, and both sides are aiming for the 3.0 agreement to take effect within 2026 and to be formally announced at this year's China-ASEAN leaders' meeting; once China completes its own procedures, the protocol could enter into force within 60 days.

In terms of trade structure, the electronics and electrical industry has been the main engine driving this round of China-ASEAN trade growth. Exports of electronic products and components, as well as electrical machinery and equipment, grew by more than 20 percent in trade with China for Indonesia, Vietnam and Thailand alike. At the same time, trade in intermediate goods has expanded especially sharply: in the first half of 2026, China-ASEAN trade in intermediate goods rose 24.5 percent year-on-year to 2.86 trillion yuan, accounting for nearly two-thirds of total bilateral trade -- underscoring how deeply integrated the two sides' industrial and supply chains have become. In terms of the division of labor, China exports complete sets of equipment, photovoltaic products and auto parts to ASEAN, while ASEAN supplies China with minerals, specialty agricultural products and electronic materials, forming a mutually complementary, two-way trade pattern. Exports of electric vehicles have also grown rapidly: in May 2026, China's monthly EV exports to ASEAN hit a record $1.2 billion, making EVs one of the fastest-growing segments of bilateral trade and a microcosm of deepening China-ASEAN cooperation in the green economy.

Among the ten ASEAN member states, Thailand is China's third-largest trading partner, behind only Vietnam and Malaysia. Agricultural trade is one of the most representative parts of the China-Thailand economic relationship, with durian trade especially prominent: in the first half of 2026, Thailand exported about 872,237 tonnes of fresh durian to China, worth more than $3.1 billion, and Thailand's Ministry of Commerce expects full-year fresh durian export value to reach about $4.6 billion. Thailand holds a dominant 81 percent share of China's fresh durian import market, far ahead of second-placed Vietnam. Electronics have also been a major force behind Thailand's export growth, both to China and globally -- Thai electronics export growth hit as high as 64.6 percent in April this year, while agricultural exports grew 17.9 percent, led by durian. However, Thailand's overall foreign trade has also seen imports growing faster than exports: in the first quarter of this year, Thai imports rose 32.4 percent year-on-year, widening the quarterly trade deficit to nearly $9.47 billion, with April import growth reaching 45 percent, the highest in nearly five years. On the free trade area upgrade, Thailand's Cabinet approved the China-ASEAN Free Trade Area 3.0 upgrade protocol on June 10, 2026, making it one of the earliest ASEAN members to complete domestic approval procedures. However, a forecast issued earlier this year by Thailand's Trade Policy and Strategy Office projected that, amid slowing demand growth in China and the United States -- Thailand's two largest external markets -- Thai export growth in 2026 could range anywhere from a 3.1 percent decline to 1.1 percent growth, suggesting that pressure from shifting external market conditions remains a live risk for Thai exporters.

Analysts attribute the sustained expansion of China-ASEAN trade in part to the combined effect of the Regional Comprehensive Economic Partnership (RCEP) and the China-ASEAN Free Trade Area. RCEP, which formally entered into force for its first batch of members on January 1, 2022, has produced an overlapping institutional effect alongside the China-ASEAN Free Trade Area; RCEP's membership extends beyond China and the ten ASEAN states to include Japan, South Korea, Australia and New Zealand, making it one of the world's largest free trade agreements by population and among the most diverse in membership. Together, the two mechanisms have lowered tariff and non-tariff barriers and provided institutional support for deeper integration of regional industrial and supply chains. The 23rd China-ASEAN Expo, held in Nanning, Guangxi, from September 17 to 21 and themed around the Free Trade Area's 3.0 upgrade, further highlighted how the upgrade is driving regional economic cooperation. As the Version 3.0 agreement moves toward the final stages of domestic approval across member states, new areas of cooperation such as the digital economy and the green economy are expected to inject fresh growth momentum into China-ASEAN trade. For Thailand, having completed domestic approval early means that once the protocol fully takes effect, its competitive export categories such as agricultural and electronic products could benefit sooner from the facilitation gains in the new areas of cooperation -- though shifts in individual countries' export structures and fluctuations in external demand will remain important factors to watch as the process unfolds.
