The Tri-Border Area is formed by the junction of three different cities: Puerto Iguazú, Argentina; Foz do Iguaçu, Brazil; and Ciudad del Este, Paraguay. Located in the eastern-central part of the Southern Cone in South America, the triple frontier region is known for its impressive Iguaçu Falls – a group of cataracts that draw over 700,000 tourists each year – and other natural sites throughout the the Iguazú National Park. The region is also notable for being the home of the world’s largest hydroelectric plant, the Itaipu Dam.

Demographically, the area is very ethnically diverse. In addition to the native Paraguayans, Brazilians, and Argentine populations, there are also substantial pockets of people of Chinese, Colombian, Iranian, Italian, Korean, Lebanese, Palestinian, Taiwanese, and Ukrainian descent. The triple frontier boasts a large Arab minority presence of around 10,000 and 75,000 people, mostly from Lebanon and Palestine.

Of the three cities that form the Tri-Border Area, Ciudad del Este is the largest and busiest, serving as the region’s economic center. Its streets are regularly clogged with street merchants, shoppers, cambistas (informal currency exchangers), and others that help fuel its burgeoning economy. In fact, Ciudad del Este has ranked third worldwide in cash transactions, averaging well over US$12 billion annually in the early 2000s.2 Foz do Iguaçu, which boasts some of the region’s most frequented tourist destinations (including Latin America’s largest mosque), is the second largest city. Puerto Iguazú rounds out the trio in terms of population size.

The FfP found that existing regional criminal networks in the Tri-Border Area have the potential to facilitate acts of WMD terrorism through: formal and informal financial networks, communications infrastructure, the provision of safe havens and identity “laundering,” and tested routes for the smuggling of personnel and materials throughout the hemisphere. Therefore, the Tri-Border Area may offer a rich enabling environment that could support a WMD terrorism scenario anywhere in the world—one characterized by corruption; gaps in the capacities of state intelligence, border security, and immigration control services; large legitimate economies and trading networks; sophisticated nuclear technology and expertise; and the presence of transnational criminal networks that overlap with the membership and activities of radical movements and terrorist elements.
