There is a very close relationship across Area Studies, World History and International Relations. World History is a first-level discipline, and International Relations is a second-level discipline under the Political Science categorized as the first-level discipline. In September 2022, the Ministry of Education released a new version of the discipline catalogue recognizing Area Studies as a first-level discipline under the catalogue of Interdisciplinary Disciplines. This discipline offers degrees in economics, law, literature and history, thus having its distinctive features and academic roots. World History has a fundamental role as the disciplinary underpinning for Area Studies and International Relations. In an interdisciplinary context, World History and International Relations have been converging around historical, contemporary and future realities. As a new huge disciplinary cluster, the establishment and construction of the first-level discipline of Area Studies has been activating the disciplinary potential for developing the World History and International Relations, overcoming their bottlenecks for development, expanding their disciplinary boundaries, enhancing the intersectional and inter-constructive capacity of the disciplines, and exploring new paths for the development of the disciplines of World History and International Relations.

The United States occupies absolute power superiority in the AsiaPacific security order, the ASEAN plays a central role in the regional mechanisms and norms, and China plays a leading role in promoting regional conceptual consensus. Various agents with its own advantage are not only the source of the weak stability of the Asia-Pacific security order, but also main factors of affecting the maintenance of regional order and structural change. The security cooperation between the United States, the United Kingdom and Australia can be traced back to the military cooperation during the Second World War, and the trilateral cooperation has challenged the regional and international order from the dimensions of power, concepts and institutions. Since September 2021, the trilateral security partnership between the US, the UK and Australia is bringing many challenges to the Asia-Pacific security order. The security partnership will complicate the power structure in the AsiaPacific region and weaken the regional and international arms control system in terms of the power dimension. The emphasis of minilateralism identified by the three sides at the conceptual level will strengthen the regional camp confrontation and divergence. While weakening the influence of the ASEAN-led mechanisms and norms, the implementation of tactics of securitization will increase the instability of the AsiaPacific security order.
