AMTI aims to promote transparency in the Indo-Pacific to dissuade assertive behavior and conflict and generate opportunities for cooperation and confidence building

The maritime environment in East Asia contains both promise and peril. The Indo-Pacific region is host to some of the world’s most important shipping lanes, facilitates huge volumes of regional trade, and boasts abundant natural resources. Competing territorial claims, incidents between neighboring countries, and increasing militarization, however, raise the possibility that an isolated event at sea could become a geopolitical catastrophe. This is all occurring against a backdrop of relative opaqueness. Geography makes it difficult to monitor events as they occur, and there is no public, reliable authority for information on maritime developments.

The Asia Maritime Transparency Initiative seeks to change this. AMTI was conceived of and designed by CSIS. It is an interactive, regularly-updated source for information, analysis, and policy exchange on maritime security issues in Asia. AMTI aims to promote transparency in the Indo-Pacific to dissuade assertive behavior and conflict and generate opportunities for cooperation and confidence building. Because AMTI aims to provide an objective platform for exchange, AMTI and CSIS take no position on territorial or maritime claims.
