Small State Diplomacy: Cambodia’s Foreign Policy Towards Viet Nam Thearith Leng A thesis in fulfillment of the requirements for the degree of Doctor of Philosophy School of Humanities and Social Sciences The University of New South Wales, Canberra March 2018 Thesis/ Dissertation Sheet Surname/Family Name : Leng Given Name/s : Thearith Abbreviation for degree as give in the University calendar : PhD Faculty : University of New South Wales Canberra School : Humanities and Social Sciences Thesis Title : Small State Diplomacy: Cambodia’s Foreign Policy Towards Viet Nam Abstract 350 words maximum: (PLEASE TYPE) This thesis is a case study of how Cambodia as a small state managed its relations with Viet Nam, a larger state. A review of the literature on small states in general and Cambodian foreign policy in particular identified three major state strategies – balancing, bandwagoning and hedging. The literature review also revealed that there was wide divergence among specialists about the specific instruments used by small states to pursue their chosen strategy. Field work was carried out in Cambodia and Vietnam to access archives and library holdings of pertinent documents and publications to supplement library research in Australia. Interviews were conducted in Cambodia and Vietnam with government officials and subject matter experts to supplement these primary and secondary source materials. This thesis examined Cambodia-Vietnam relations in seven historical periods from 1620 to 2017 during which Cambodia experienced marked changes in regime type from a weak pre-colonial state (1620-1863), French protectorate (1863-53, independent kingdom (1953-70), republic (1970-75), communist/Khmer Rouge (1975-79), occupied client state (1979-89) United Nations supervision (1990-93), coalition government (1993-97) and one-party state (1997-17). Cambodia’s foreign policy was analyzed through the framework of three levels of analysis – decision-making, nation-state and systemic. The first level of analysis focused on key decision-making structures, the worldview of decision-makers and the kinds of decisions they made (crisis, declaratory, program). The second level of analysis focused on the internal characteristics of the state such as geography, natural resources, economy, and the political system. The third level of analysis focused on the impact of changes in the distribution of regional and global power on Cambodia. The major conclusion of this thesis was that although various Cambodian regimes pursued a hedging strategy towards Viet Nam they each used different instruments. The major finding of this thesis is that the academic literature neglected two unique instruments used by Cambodia as a small state as part of its hedging strategy towards Viet Nam – influence denial and hard balancing. The thesis concluded that the present government of Cambodia pursues a hedging strategy best characterized as cooperative hedging.
