This book examines how Asian countries have responded to urgent challenges against a backdrop of climactic political developments, as well as the effects of issue linkage in policy making. Chapters are arranged according to localities but interlinked through their thematic and critical analyses. The section on Hong Kong focuses on the theme of protests, highlighting its intersection with identity and generational shifts in addition to legal, political and economic changes before and after the adoption of Hong Kong National Security Law. The section examining Taiwan’s policies discusses electoral calculations, identity reconstruction, cross-Strait stalemate and alliance maneuvers within USA-China-Taiwan triangular international relations, providing an overview of its domestic and external policies. Through their analysis, the authors here determine that China has emphasized the prerogatives of history, culture and territorial sovereignty in its dealings with the Hong Kong protests and Taiwan, and that cross-Strait analysis must be deliberated and ultimately determined within the USA-China-Taiwan triangular framework. In the final section, authors examine the USA’s role and policy in dealing with both sides of the Taiwan Strait. Hegemonic power transition has been a primary concern in both countries with the USA’s hegemonic status facing daunting challenges from China, increasingly perceived as an ascending revisionist power waiting to overtake the USA in the future.
