The assumption in academic IR literature is that the size of small states automatically makes them vulnerable and weak, without any power to shape decisions of middle power states. This thesis examines the relationship between small states, the Pacific Islands, and regional middle power Australia. In order to answer the question “How do the Pacific Island States, as small states, attempt to exert influence on climate change decisions over middle power state Australia in the international environment?” this study employs a qualitative research design of small and middle power states. By showing collective leadership through the United Nations, the PIS are able to influence debates and agenda-setting of middle power states on the norm climate change at the international level. However, the influence of small states on Australia’s climate policies is limited and depends on the receptiveness of the Australian government. Yet, the current geopolitical competition between Australia and China occasionally offers the PIS opportunities to pressure the Australian government.Show less
