The isolated hills in landlocked Laos have become the newest portion of a multi-billion-dollar highway system connecting China to Southeast Asia. Laos, a region once impoverished by decades of conflict and isolation, now finds itself in the middle of a fast-paced flow of people, goods and services benefiting from China and the Asian Development Bank’s decade-long plan for an integrated regional trade route.

A new road linking Laos to its richer neighbors brings up the question of balance between rapid economic progress and environmental protection in less-developed countries. While Laos is certainly among the world’s most environmentally pristine countries, and for that reason an appealing backpacking destination, its people seek a life beyond meager trading in opium and tiger bones.

Laos is the final link in a 6,500-kilometer overland route expected to boost trade and tourism from Singapore to Beijing. Supporters of this regional highway network argue that the new trade route will help reduce poverty by providing access to markets, income, and employment opportunities. According to the International Herald Tribune, total trade between China and the Southeast Asian countries of Cambodia, Laos, Myanmar, Thailand and Vietnam has risen from $5.7 billion a decade ago to $53 billion in 2007. The highways will also provide people with easier access to social services, such as health clinics, and increase revenue in the tourism sector.

Critics from abroad, however, are quick to argue that the network of highways will contribute to widespread pollution and natural resource depletion as well as promote illegal wildlife and timber trade.

For Laotians, the concerns aren't environmental but social.

Lao expert Martin Stuart-Fox of Australia's University of Queensland said many Lao people now feared the "truck-stop development" of their country.

"Lao friends of mine fear that social ills such as HIV/AIDS and prostitution will flourish, and that it will make it easier to lure young Lao to be exploited — sexually and otherwise — in Thailand and Vietnam."
