This article examines the significance of mobility and transportation infrastructure in the early development of pan-Americanism and the formation of a vision of global transportation in South America in the late nineteenth century. Focusing on the 1880s and 1890s, I explore the connection between transportation and the economic and cultural expansionism of the United States, pan-American debates on intercontinental steamship service and an inter-American railroad, and South American approaches to international transportation, which both included and transcended the Americas. My case study contributes to scholarship on the global history of mobility and transportation by showing how, despite the intention of the United States to establish hemispheric exclusivity and hegemony, transportation became a subject of multilateral cooperation. South American experts and diplomats, I argue, renegotiated and reinterpreted the meaning of pan-American infrastructure, integrating it into a broader vision of global transportation that positioned their countries more prominently in worldwide traffic networks.

From the early 1950s, the USSR was the second largest contributor to the UN. Following UN rules, it gave much of its contribution in rubles, an infamously unconvertible currency that generally limited Soviet actions overseas. In the hands of UN officials, however, these ‘weak’ rubles became a powerful lever that made UN development projects more Soviet. Seeking to extract value from the ruble, officials increased the amount of UN development training held in the USSR, prioritized the purchase of Soviet equipment, and incentivized agencies to distribute Soviet manuals. Exploring the ruble lever contributes to our knowledge of the Soviet presence at the UN while foregrounding political economy as a key mechanism shaping UN practices more widely. Following the money in forms other than the dollar can reveal how economies of power at the UN intersect with global economic history, as well as the conceptual and contemporary challenges of international cooperation among wildly unequal economies.
