According to Thailand’s English-language outlet Nation Thailand, China is planning to deepen strategic cooperation with Thailand in what is being called the ‘Golden 50 Years’ of bilateral ties, focusing on three key areas: artificial intelligence (AI), the green economy, and the digital economy. Beijing says the two countries will strengthen cooperation on supply-chain connectivity, investment facilitation and emerging technologies to push the bilateral relationship to a higher level. The renewed push follows the momentum built during 2025’s commemorations of the 50th anniversary of China-Thailand diplomatic relations, and coincides with 2026 marking the opening year of China’s 15th Five-Year Plan.

China and Thailand formally established diplomatic relations on July 1, 1975, a milestone in China’s relations with Southeast Asia. 2025 marked the 50th anniversary of that relationship, and the two sides held a series of ‘Golden 50 Years’ commemorative events, including a state visit to China by King Maha Vajiralongkorn — the first time a Thai monarch has made a state visit to China, widely seen as a landmark symbolic moment for bilateral ties. Meeting the Thai king, Chinese President Xi Jinping said China was ready to work with Thailand to continue building a China-Thailand community with a shared future and write a new chapter of friendship, expressing hope the two sides would jointly open the next ‘Golden 50 Years.’

Earlier this year, after the conclusion of China’s ‘Two Sessions,’ Chen Haiping, Chinese Consul General in Chiang Mai, told Thai media in an interview that China planned to keep strengthening strategic cooperation with Thailand under the ‘Golden 50 Years’ framework, with AI, the green economy and the digital economy as the three priority areas. He also pointed to joint action by China, Thailand and Myanmar against cross-border telecom scam networks, particularly around Myawaddy and its surrounding areas in Myanmar. The three countries set up a ministerial-level coordination mechanism in early 2025 and have since carried out multiple rounds of joint crackdowns; more than 1,500 suspects have been repatriated to China, and over 630 buildings inside Myawaddy’s ‘KK Park’ scam compound have been demolished.

Ties advanced substantively in July. Thai Prime Minister Anutin Charnvirakul made his first official visit to China since taking office, from July 16 to 20, meeting President Xi Jinping in Shanghai and holding talks with Premier Li Qiang in Beijing. He also attended the 2026 World Artificial Intelligence Conference (WAIC) in Shanghai and presided over the opening of a new overseas office of Thailand’s Board of Investment (BOI) in Chengdu. The visit produced 15 signed cooperation agreements covering science, aerospace, education, AI, trade, intellectual property and water management, along with pledges from Chinese businesses to expand investment in Thailand by more than 70 billion baht, expected to create over 10,000 jobs.

On July 21, the Chinese and Thai governments issued a joint statement on building a China-Thailand community with a shared prosperous future, explicitly committing to deepen cooperation in the digital economy and AI, advanced electronics, modern automobile manufacturing, future foods, aerospace and space technology, quantum technology, clean energy and bio-industries. The two countries also launched a new multi-year trade and economic cooperation plan targeting strategic sectors such as semiconductors, batteries and sustainable production, and plan to establish a digital economy cooperation platform linking finance, cross-border trade and AI research.

On July 22, the Thailand-China Cooperation Expo 2026 opened in Bangkok under the theme ‘Investing for the Future, Growing Together,’ upgrading what had been a traditional trade exhibition into a comprehensive platform linking capital, technology, innovation and business networks. In his opening remarks, Anutin gave an unusually forceful endorsement of Chinese investment, promising bureaucratic reform, personal guarantees of investor security, and warning that officials who slowed approvals would face consequences. On the ground, Thailand’s Eastern Economic Corridor (EEC) recently approved a 10-billion-baht robotics investment led by five Chinese technology firms to build a humanoid robot components cluster in Chachoengsao province. Separately, the prime minister and Digital Economy and Society Minister Chaichanok Chidchob held high-level talks with China’s Huawei on expanding cooperation in AI infrastructure, next-generation data centres and digital talent development, as Thailand seeks to position itself as Southeast Asia’s AI hub — while also stressing it intends to stay neutral in the broader US-China AI competition.

On the green economy, Thailand has continued sharing its experience with the Bio-Circular-Green (BCG) economic model, while China has presented its ‘Beautiful China’ development approach. As co-chairs of the Lancang-Mekong Cooperation mechanism, China and Thailand said they would work closely with other member states to address regional environmental and climate challenges, build a green economic development belt along the Lancang-Mekong basin, and strengthen the green momentum of ‘LMC 2.0.’

On security, China and Thailand also confirmed plans to establish a new 2+2 ministerial dialogue mechanism spanning foreign affairs and defence, to coordinate responses to transnational crime — including telecom scam syndicates, organised crime, money laundering and human trafficking. The mechanism is seen as further institutionalising the existing China-Myanmar-Thailand trilateral crackdown framework; its first meeting is expected to be held in China and will focus on scam networks, illicit businesses, money-laundering networks and the wider transnational crime chain.

Underpinning this deepening cooperation is a steadily expanding trade relationship. According to China’s Ministry of Commerce, bilateral trade between China and Thailand topped 1 trillion yuan (about US$147.8 billion) in 2025, up 15.1 percent year on year, with Thailand’s exports to China at roughly US$39.72 billion and imports from China at about US$107.62 billion. China has remained Thailand’s largest trading partner for several consecutive years, while Thailand is a significant partner for China within ASEAN. Analysts say this expanding trade base provides the practical foundation for the two sides to deepen cooperation on supply-chain connectivity, investment and new technologies under the ‘Golden 50 Years’ framework.

Analysts note that the shift from the largely symbolic diplomatic commemorations marking the 50th anniversary of ties in 2025 to the wave of investment deals, joint statements and institutionalised dialogue mechanisms rolled out through 2026 shows China-Thailand relations moving from ceremonial celebration into the substantive agenda of the ‘Golden 50 Years’ era — one built on AI, the green economy, the digital economy and security cooperation as its pillars. As China moves fully into its 15th Five-Year Plan, whether the two sides can convert high-level pledges into concrete projects and durable institutional arrangements will be the key measure of success for this new phase of the relationship.
