Chinese state-owned Sinohydro Corp. finished building the 193-megawatt Kamchay hydroelectric dam in Cambodia in 2011 — the largest of five dams in the Southeast Asian country. Cambodian authorities aim to counter domestic power shortages in Kampot, Phnom Penh and Preah Sihanouk province, as well as sell some of the electricity generated. Chinese companies are also building a dam in Pursat province and on the Tatai River in Koh Kong province, although environmentalists have raised concerns over land grabs and deforestation. China is Cambodia’s largest investor, having poured $9.7 billion into the country over the past 18 years, according to Radio Free Asia, citing a government report.
Cost: $280 million
