The latest statistics from Thailand's Ministry of Commerce show that over the first eight months of 2026, Thailand's trade deficit with China widened to roughly $62.7 billion, with China remaining by far Thailand's largest source of trade deficit. One point worth clarifying: that $62.7 billion figure is the bilateral deficit with China alone, while Thailand's overall trade deficit with the entire world over the same period stood at $37.8 billion — because Thailand still runs surpluses with some other trading partners, its deficit with China alone actually exceeds its total global deficit. In other words, the deficit generated by China alone is larger than the net effect of Thailand's trade balance with every other country and region in the world combined, a structural imbalance that continues to drive domestic policy debate in Thailand.

More granular seven-month data further reveals the drivers behind this imbalance. Over the first seven months, bilateral Thailand-China trade totaled $108.804 billion, up 29.89% year-on-year, but within that, Thailand's imports from China surged 38.49% while its exports to China grew just 9.17% — a stark growth gap that pushed the bilateral deficit for the period to $55.13 billion, up a sharp 59.31% year-on-year. By category, imports of electrical machinery and components jumped about 83% year-on-year to $19.373 billion, the single largest category driving the widening deficit, closely matching the trend of Thailand attracting heavy Chinese investment in electric vehicles, batteries and electronics in recent years, which requires importing large volumes of related machinery and raw materials from China.

In contrast to the overall trade imbalance, durian — Thailand's "flagship" export to China — continued to perform strongly in 2026. Data show Thai durian exports neared $3.8 billion in the first half of 2026, a sharp rise from roughly $2.56 billion in the same period a year earlier, with Thailand holding steady at an 81% share of the global durian export market, continuing to lead Southeast Asia's durian-exporting countries. Meanwhile, Chinese customs data show China's durian imports rose 47% year-on-year in the first half of 2026, with both Thailand and Malaysia benefiting from the surge in demand; although Vietnam's durian shipments to China have expanded rapidly and were once seen as a challenge to Thailand, they have yet to dislodge Thailand's leading position. The durian trade's buoyancy has, to some extent, become one of the few areas where Thailand still retains an export advantage and strong growth momentum in its economic relationship with China.

Analysts say the fundamental cause of Thailand's widening trade deficit with China lies in the deep structural differences between the two countries' export profiles. Thai exports to China remain heavily reliant on lower- to mid-tier products such as computer parts, fruit (durian in particular) and rubber products, while imports from China are dominated by capital goods and intermediate products such as electrical machinery, mechanical equipment and electronic components. Kasikorn Research and other institutions have argued this widening trend reflects a structural weakness in Thailand's export industry — the country still lacks new pillar industries capable of sustaining export growth going forward, comparable to Vietnam's semiconductor manufacturing sector, leaving Thailand in a relatively passive position in its industrial division of labor with China. Overcapacity in China's manufacturing sector, its export-oriented policies, and US-China trade friction pushing Chinese manufacturers to seek alternative export markets including ASEAN are also seen as external factors accelerating the influx of Chinese goods into the Thai market.

Thai industry has already sounded warnings and proposed responses. The Thai-Chinese Chamber of Commerce has publicly called on the Thai government to accelerate implementation of a "local content" policy, requiring foreign-invested factories in Thailand — particularly in the electric vehicle and electronics industries — to raise the share of locally sourced raw materials and components, so as to generate more domestic value-added and build up local supply chains rather than merely serving as assembly bases. Analysts also note that while heavy Chinese capital has flowed into Thailand's EV and electronics manufacturing in recent years, much of the new investment relies heavily on automation and robotics, limiting its effect on local employment and local component procurement — an important backdrop to the rising calls for a local-content policy. Thai academics have also proposed other approaches, including refining industrial policy, diversifying export markets beyond China, and pushing for more balanced trade with markets such as the United States, in hopes of easing the distorting effect the China trade imbalance has on Thailand's macroeconomic data.

The persistent widening of Thailand's trade deficit with China has also sparked debate over whether the country's own macroeconomic statistics may be distorted. Some Thai economic observers note that Thailand's trade deficit with China has climbed from roughly $35 billion in 2023 to more than $60 billion in just the first eight months of this year — a far faster rate of increase than any other bilateral trade relationship — meaning that judging Thailand's overall trade performance purely by its "headline export growth rate" risks masking the real state of industrial competitiveness. Thailand's still-growing overall export figures are partly driven by high-tech transshipment trade and assembled-goods exports, which reflect multinational supply chains "passing through" Thailand rather than a genuine improvement in domestic industrial competitiveness. Some commentary suggests that stripping out the single variable of China trade, Thailand's overall trade position with its remaining partners is actually relatively healthy — which is why some academics argue policy debate should focus specifically on the "structural deficit with China" rather than discussing Thailand's overall trade balance in broad terms.

Looking at the full year, some market forecasters estimate that if current trends continue, Thailand's full-year 2026 exports to China could reach around $41.5 billion while imports from China could climb to about $117 billion, widening the full-year bilateral deficit to roughly $75.5 billion — a further deterioration from the previous year. Thai Commerce Ministry officials say the government is maintaining dialogue with industry to assess how industrial-policy adjustments could gradually narrow the structural deficit while preserving the broader economic and trade relationship with China. Against this backdrop, while durian's continued strength cannot fundamentally reverse the overall picture of Thailand's trade imbalance with China, it at least demonstrates that Thailand retains strong international competitiveness in its specific areas of strength — a point Thai officials have repeatedly emphasized in related policy discussions and used as one of their bargaining chips in economic and trade negotiations with China.
