- The emergence of the ASEAN Outlook on the Indo-Pacific provides a new nuance in the discourse on the Indo-Pacific that has emerged for a long time. The emergence of this outlook cannot be separated from Indonesia's significant role in several drafting processes. Despite experiencing doubts within ASEAN members, Indonesia is still trying hard to get this regional organization to approve its proposal. This study seeks to trace why Indonesia is so determined to formulate the ASEAN Outlook on the Indo-Pacific. Using Bueger's concept of maritime security, this study argues that Indonesia has an interest in realizing maritime security both at the internal and regional level in the ASEAN Outlook on the Indo-Pacific. The interests are in four areas: economic development, national security, human security, and the marine environment.
