Speaker

Dr. Christian Lentz

This presentation examines diplomatic relations between Indonesia and the two Vietnams from 1955-65, when political elites toggled between commitments to free themselves from colonial rule on the one hand and imperatives to fill out territories defined by colonial rule on the other.

All three countries sent delegates to the 1955 Asia-Africa Conference in Bandung and embraced its principles of self-determination, anticolonialism, and equality among nations. Yet subsequent diplomatic, political, and military maneuvers demonstrate that Vietnamese and Indonesian elites used the same Bandung principles to legitimize the conquest of territory created by former colonial overlords.

Putting the principle of “respect for the sovereignty and territorial integrity of all nations” to work, Presidents Sukarno of Indonesia and Ho Chi Minh of northern Vietnam (DRV) made common cause in their respective pursuits of western New Guinea, left out of the 1949 settlement with the Netherlands, and southern Vietnam (RVN), administered separately since the 1954 Geneva Agreements. Called “national reunification” in archived documents, their projects endeavored to create national territories that, in fact, had never existed before. Caught in between, RVN leaders worried about the expansionist ambitions of both and, consequently, drew closer to the US in a heating Cold War contest. Taken together, the irredentist pursuit of territory in Southeast Asia suggests how Bandung principles exceeded anti-colonial solidarity and became, instead, tools of postcolonial recolonization.
