Where Do Thailand-China Relations Stand in 2026?

This year is set to witness a flowering of relations between Bangkok and Beijing – but Thai strategists remain both ambivalent and wary.

Thailand’s Foreign Minister Sihasak Phuangketkeow has garnered significant attention with his latest interview with The Washington Post, in which he expressed unambiguous opposition to the United States’ war with Iran and spoke favorably about China and Russia. China is, of course, the bigger partner for Thailand, with many existing indicators of closeness spanning trade, political leadership, socio-cultural ties, and defense.

April alone has seen many good developments in Thailand-China ties, sustaining the momentum from last year’s Golden Jubilee celebration of their modern diplomatic relations. Chinese Foreign Minister Wang Yi was just in Thailand last week, where he stopped in Bangkok and the southern resort province of Krabi for high-level talks. Ahead of his trip, Chinese Ambassador to Thailand Zhang Jianwei was apparently the first foreign envoy to pay a courtesy call on Thailand’s new defense minister, Lt. Gen. Adul Boonthamcharoen.

Beyond the official circles, the 47th Bangkok International Motor Show saw China’s BYD – the very brand endorsed by Thailand’s Prime Minister Anutin Charnvirakul for personal use and for chauffeuring Foreign Minister Wang – topping the booking numbers, beating the long-favored Toyota from Japan. In fact, eight of the top ten most booked car brands were Chinese-owned.

Thailand-China ties look set to blossom. First, there is a clearer convergence of interests. Both Thailand and China are highly reliant on oil imports, and the “new normal” of disruptions surrounding maritime chokepoints unites them in accelerating the transition toward clean energy as well as searching for alternative suppliers and trade routes.

For Thailand’s government, the “land bridge” megaproject to transport goods between two deep-sea ports at the opposite ends of the Thai national coasts, connecting the Indian and Pacific oceans via railroads, is increasingly framed less as a soft policy preference and more as an insurance for strategic independence (subject to cautious management). Striving to lower reliance on the Strait of Malacca since the early 2000s, when the then Chinese President Hu Jintao introduced the expression “Malacca dilemma,” China stands among the most probable backers of Thailand’s land bridge, whether diplomatically or financially.

Second, as Foreign Minister Sihasak stressed, China’s predictability is prized more than ever. This could foster a closer correlation between practical cooperation and trust levels, which do not necessarily move in lockstep. One could reasonably assume that Thailand already has a great deal of trust in China. This is because their problems revolve around the more fluid and positive-sum – however serious – economic and security issues, such as trade deficits and  water governance in the Mekong River, and not the inherently zero-sum matters of territorial disputes and historical trauma.

That the Thailand-China relationship today is free of historical trauma might be met with skepticism, considering that Thailand’s entrenched nationalist narrative of “14 territorial losses” between the late eighteenth and twentieth centuries includes the loss of Sibsongpanna (Xishuangbanna) to China. One counterargument, leaving aside the debate over whether Sibsongpanna was ever part of the Thai state, would be that such a loss was not dictated by unequal treaties in a manner similar to Thailand’s dealings with Western imperial powers. Looking back some four centuries earlier, Thailand was never subject to Chinese invasion, nor is China’s Tributary System recalled today as oppressive.

Thai sentiments are,........
