Perhaps most importantly, issuing a joint climate statement would signal major diplomatic leadership amid global fragmentation. When the EU and China came together in July, despite tensions over trade, rare earth access, geopolitics and Ukraine, they underscored climate action as a rare area of cooperative diplomacy. ASEAN and China could similarly claim a space in climate governance – not as pitted blocs, but in symbiosis. Such a compact would elevate ASEAN’s standing from passive platform to unified partner, offering global climate diplomacy a Southeast Asian dimension.
Sceptics may see ASEAN as wary of climate treaties – for example, its legally binding haze agreement only emerged in 2002 after lengthy resistance to relinquishing sovereignty. The so‑called “ASEAN Way” prefers non‑interference, consensus building and minimal institutionalisation. That approach may have constrained bold climate action. But ASEAN’s own Centre for Climate Change, now in development, offers an institutional basis for coordination; ownership over such a compact would preserve ASEAN centrality while granting legitimate scope for collective discipline.
Timing is favourable. ASEAN led last year’s COP 29 collective statement, reaffirming Paris commitments, principles of common but differentiated responsibilities, and highlighting the slow progress in climate finance and emissions cuts. China‑ASEAN dialogue frameworks already endorse sustainable development, clean energy, and capacity building. What is missing is a synchronized deliverable – a jointly endorsed ASEAN‑China compact, dated, measured, and designed to deliver substance before the world meets again in Brazil at COP 30.
ASEAN’s vulnerabilities to coastal storms, heat waves, supply chain disruptions, and food insecurity demand unity. China’s growing climate diplomacy investments and ASEAN’s growing institutional coherence present the ingredients for success. A jointly issued climate compact, mirroring the structure of the EU‑China declaration, would bind ASEAN and China together in a shared trajectory of emission targets, green finance, technology access, and adaptation support.
The ASEAN‑China climate compact would mark a transformation from aspirational statements to operational ambition. It would shift from national silos to regional alignment. Passive resilience would give way to active leadership. Just as the EU and China chose climate cooperation as a stabilising signal amid tension, ASEAN and China can choose to lead, anchored by the Paris Agreement and propelled by shared urgency. In doing so, Southeast Asia would become not only a region at risk – but a region of climate governance.
