Ngu Ik Tien explores how Malaysia’s Barisan Nasional (BN) regime—once celebrated as a model of consociational democracy—achieved broad political domination through its structures and systems across the country, including in the Chinese-majority municipality of Sibu in Sarawak. However, the study reveals how the regime deviated from ideal consociational principles, ultimately alienating ethnic minorities and fueling the rise of subnational regionalism. The book focuses primarily on the role of Chinese timber tycoons under the leadership of the Sarawak United Peoples’ Party (SUPP). Their influence over local social and political domains enabled them to broadly dominate local society. Through these local institutions, they established deeply rooted patron–client networks, parts of which were integrated into the Sarawak Barisan Nasional (SBN) machinery. However, growing local opposition meant that even politically well-connected timber tycoons could never achieve full domination. The increasing limits of these political structures led to the convergence of local and national forces calling for regime change and the subsequent rise of Sarawak regionalism discourse, which continues to structure Malaysian politics following BN’s fall from power in 2018. This provides valuable insights into how politics unfolds on the ground by decentering state-centric narratives to emphasize their entanglement with society and regime continuity in the present. Ethnic Chinese Politics in East Malaysia, 1945–2018: From Timber-tycoons to Sarawak Regionalism is a valuable book for academics and scholars of Malaysian politics, consociational democracy, ethnonationalism, the ethnic Chinese political economy of Southeast Asia, and regionalism. It is also of interest to researchers and think tanks in political science, Southeast Asian studies, and comparative politics, as well as those studying regime transitions, state–society relations, and informal political networks.
