Drawing evidence from governmental datasets, policy reports, and other sources, this paper, focusing on the clean energy transition as the key aspect, examines Canada’s current approach to climate cooperation with ASEAN countries to “build a sustainable and green future,” echoing one of the strategic goals in Canada’s newly released Indo-Pacific Strategy (IPS). In particular, this paper argues that the current policy and financial assistance from Canada to ASEAN countries is unequal and insufficient. Moreover, there is a lack of continuity and measurable objectives within this cooperative framework, which primarily operates within a multilateral context. Given these characteristics, we propose that Canada's cooperation with ASEAN nations in addressing climate change should integrate the imperative for a clean energy transition. This approach has the potential to create numerous opportunities for engaging with ASEAN countries, while also aligning with the objectives of the IPS. Specifically, to enhance the effectiveness of IPS in this context, the Canadian government should emphasize experience sharing, fortify its business collaboration with ASEAN countries, and participate more actively in ASEAN-led initiatives.
