On December 2，2019，the Malaysian Pakatan Harapan government officially launched the country’s first ever Defence White Paper. With the theme of “a secure，sovereign and prosperous nation”，the white paper outlines the country’s blueprint of defence policy for the next decade. In contrast to the Dasar Pertahanan Negara （Malaysian Defence Policy） released in 2010，Malaysia’s current Defence White Paper re-evaluates its strategic environment and pays special attention to address non-traditional security issues. The white paper also points out that as a maritime nation with continental roots，Malaysia need to focus on both the land and the sea. However，the implementation of the white paper could be disturbed by the incoherence in the Malaysian government’s policies and the uncertainty of the Southeast Asian region as a whole.
