Morales has nationalized a series of foreign companies since first taking office in 2006 that he considers public utilities and thus property of Bolivia's people.
On Dec. 30, his government took over electricity distribution subsidiaries of the Spanish energy company Iberdrola.
In May, he nationalized Transportadora de Electricidad belonging to Spanish company Red Electrica, which controlled 74 percent of energy transmission in Bolivia.
In his first year in office, Morales renegotiated contracts with a dozen hydrocarbon companies, including Repsol, Petrobras, BG and Total, to provide Bolivia with a greater share of revenues from natural gas production.
In 2009 Morales transferred to state control the country's largest telephone operator, which had been controlled by Italy's ETI, and in 2010 he did the same with the four largest power generators, which had belonged to French-owned Suez, Rurelec of Britain and Bolivian shareholders.
