At a summit in Brussels, Brazilian President Dilma Rousseff said the $185 million cable project was central to "guarantee the neutrality" of the Internet, signaling her desire to shield Brazil's Internet traffic from U.S. surveillance.

"We have to respect privacy, human rights and the sovereignty of nations. We don't want businesses to be spied upon," Rousseff told a joint news conference with the presidents of the European Commission and the European Council.
