The Royal Thai Government veteran Phinij Jarusombat told a major regional environmental summit that international partnerships on climate and conservation are no longer optional—they are the foundation of shared economic survival. Speaking before delegations from more than 30 countries in China's Yunnan province on May 30, 2026, the former deputy prime minister positioned Thailand's green development trajectory within a broader context of how emerging economies are addressing decarbonization while maintaining economic growth.
Why This Matters:
• Policy signal: Thailand is signaling continued alignment with China's Belt and Road green cooperation frameworks, which channel investment into clean energy and low-carbon infrastructure across Southeast Asia.
• Regional competition: As Indonesia, Malaysia, and Vietnam ramp up green investment campaigns, Thailand's voice at this forum reaffirms its Bio-Circular-Green (BCG) model as a distinct national strategy.
• Reference case: Yunnan's Erhai Lake restoration project—cited by Jarusombat—offers a case study approach for how Thailand could potentially address its own water quality challenges in tourist-dependent regions like Chiang Mai and Phuket.
Dali Forum Spotlights Environmental Diplomacy
Jarusombat delivered his remarks at the Global Ecological Civilisation Forum, colloquially known as the "Erhai Lake Forum," hosted in Dali on May 30, 2026. The event was co-organized by the State Council Information Office of China, the People's Government of Yunnan Province, and the China Public Relations Association, drawing over 200 participants including policymakers, academics, and civil society representatives.
The former deputy prime minister, who currently serves as president of the Thai-Chinese Cultural Relationship Council, used the opening session to argue that climate change and environmental degradation do not respect borders. "The benefits of forums like this extend globally," he said, emphasizing that ecological preservation contributes directly to long-term prosperity and quality of life. He singled out Dali's conservation efforts around the Cangshan Mountains and Erhai Lake as a "living example of green development" with potential relevance to Thailand.
Erhai Lake itself has become a showcase project for China's environmental governance. Once threatened by agricultural runoff and rapid urbanization, the lake's water quality has markedly improved following a decade of wetland restoration, wastewater treatment expansion, and limits on phosphorus-heavy fertilizers. For Thailand, where algae blooms and industrial pollution have periodically affected beaches and inland fisheries, the Yunnan model demonstrates how tourism revenue could potentially be balanced with ecosystem health—though implementing similar approaches would require substantial fiscal commitment and enforcement capacity.
Thailand's BCG Model Meets China's Legal Push
Jarusombat's remarks arrived as China rolls out its most ambitious environmental legal framework to date. In March 2026, Beijing adopted the Ecological and Environmental Code (EEC)—a unified statute consolidating more than 30 national laws and over 1,000 local regulations—set to take effect August 15, 2026. The code includes a pioneering chapter on "Green and Low-Carbon Development," which elevates China's dual carbon goals (peaking emissions before 2030, achieving carbon neutrality before 2060) from policy targets to legally enforceable norms.
The code also establishes a dual trading framework for mandatory carbon emission permits and voluntary offset credits, expanding China's national Emissions Trading Scheme (ETS) to sectors including cement, steel, and electrolytic aluminum, with chemicals, petrochemicals, civil aviation, and papermaking slated to join by 2027.
For Thailand, which has long promoted its Bio-Circular-Green (BCG) Economy Model as a comprehensive sustainability framework, the Chinese legal architecture presents both a benchmark and a potential reference point. The Thailand BCG model integrates bioeconomy (sustainable use of biological resources), circular economy (waste reduction and resource efficiency), and green economy (balancing economy, society, and environment)—a holistic approach that Thailand actively markets at APEC, UN forums, and bilateral dialogues.
Yet while Thailand's BCG model emphasizes sufficiency economy philosophy and leverages the country's biodiversity and cultural richness, it has not yet been anchored in a single comprehensive legal code. The Thailand Ministry of Natural Resources and Environment oversees a patchwork of statutes governing air quality, waste, and water, but observers note that enforcement remains inconsistent and that investment incentives for green technology lag behind regional competitors.
Regional Green Investment Race
Thailand is navigating a crowded field. Indonesia has positioned itself as a destination for green capital flows, showcasing its Just Energy Transition Partnership (JETP) aimed at replacing coal with renewables. At the Indonesia International Sustainability Forum (ISF), Jakarta highlights climate-resilient agriculture, bioenergy, sustainable transport, and downstream processing of critical minerals.
Singapore leverages its Green Plan 2030, focusing on urban sustainability, clean energy, and carbon pricing schemes, and shares expertise through the Singapore Cooperation Program. Malaysia has rolled out a Green Investment Strategy (GIS) aligned with its New Industrial Master Plan 2030 and National Energy Transition Roadmap, targeting a net-zero ambition by 2050. Vietnam is courting private investment to support its 2050 net-zero target, positioning itself as a hub for green production and innovation.
Against this backdrop, Thailand's participation in the Dali forum signals an important diplomatic positioning: regional environmental cooperation, particularly with China, could potentially unlock technology transfer, infrastructure finance, and market access as part of broader Southeast Asian development strategies.
What This Could Mean for Residents
For expats, investors, and long-term residents in Thailand, Jarusombat's Dali appearance reflects Thailand's diplomatic engagement on environmental cooperation. While the speech did not announce specific bilateral initiatives, here's what analysts are monitoring:
• Potential energy transition funding: If Thailand pursues closer alignment with China's Belt and Road Energy Partnership, this could eventually lead to concessional loans or joint ventures for solar, wind, and battery storage projects, particularly in the Eastern Economic Corridor (EEC) industrial zones. However, such arrangements would require separate bilateral negotiations and Thai government approval.
• Possible water quality enforcement: Should Thailand adopt governance approaches similar to Yunnan's model, there could eventually be stricter discharge limits for factories and farms near sensitive waterways. Property owners near coastal zones or inland lakes might face new zoning restrictions or higher environmental fees—though implementation would depend on political will and resource allocation across Thailand's 77 provinces.
• Carbon market development consideration: While Thailand's voluntary Thailand Voluntary Emission Reduction Program (T-VER) has operated since 2013, the country has not yet launched a mandatory compliance market like China's ETS. Thai regulators may eventually study the Chinese model, which could eventually lead to phased carbon pricing for cement, petrochemical, and aviation sectors—but this remains speculative and would require separate policy decisions.
• Potential green trade opportunities: As China expands its Global South-South Development Facility (endorsed in May 2026 with an initial USD 10 M contribution), Thailand may eventually gain access to climate tech pilot programs, agricultural sustainability grants, or green supply chain certifications that could ease exports to China's consumer market—contingent on bilateral agreement and negotiation.
Forum Agenda and Next Steps
The Dali gathering tackled a broad agenda: environmentally friendly agricultural technologies, ecological governance, international cooperation, people-to-people exchanges, and sustainable city development. Jarusombat's remarks aligned with these themes but, notably, stopped short of announcing specific bilateral initiatives. This reflects Thailand's careful diplomatic balance: maintaining economic engagement with China while preserving policy autonomy and engagement with other international partners on climate finance.
In February 2025, a Joint Statement between Thailand and China pledged continued cooperation on clean energy development and energy transition, including potential work within the Belt and Road Energy Partnership. The Plan of Action to Implement the ASEAN-China Comprehensive Strategic Partnership (2026-2030), adopted in 2025, explicitly supports collaboration on green industrialization, new and emerging energy technologies, and mobilizing green investment. China is currently the leading source of public clean energy investment for Southeast Asia.
However, translating summit pledges into on-the-ground projects requires navigating Thailand's regulatory approval process, local permitting, and political considerations. Recent promotional activities related to clean energy investment in Bangkok and the presence of Thai officials at China-hosted forums suggest ongoing engagement, but residents should expect gradual rather than rapid shifts in energy and environmental policy.
Lessons from Yunnan
Jarusombat's reference to the Cangshan Mountains and Erhai Lake conservation efforts highlighted a case study. Yunnan province has spent the last decade restricting phosphorus fertilizer use, relocating polluting factories, and building ring-road wastewater treatment plants around Erhai Lake. The result: water quality classification improved from Grade IV to Grade III, meeting national standards for drinking water sources.
For Thailand, where Chiang Mai's Ping River, Phuket's beaches, and Bangkok's canals have faced recurring pollution challenges, the Yunnan experience illustrates the sustained commitment and capital investment required to address ecosystem decline. It also demonstrates the complexities involved: some agricultural livelihoods were affected, and local governments took on significant financial commitments to finance infrastructure upgrades.
Whether Thailand adopts a similar approach depends on fiscal capacity, enforcement credibility, and public support—all of which remain variable across the country's 77 provinces. Any such shift would require separate policy decisions by Thai authorities, not automatic adoption of foreign models.
