WASHINGTON \u2013 U.S. cloud providers have ambitious designs on foreign markets, but overseas expansion has been slowed by a number of obstacles, ranging from privacy worries over government surveillance activities to policies that impede cross-border data flows.\nIn response, top Obama administration officials say they're pressing other nations on open Internet issues as they negotiate trade agreements and working to repair some of the damage done by the revelations of Edward Snowden, the former NSA contractor.\n[ More: US Faces Major Internet Image Problem ]\n"Certainly this is a very central and important part of the administration's trade agenda," Christine Bliss, assistant U.S. trade representative for services and investment, said Thursday at an event hosted by the Brookings Institution. "We start from the premise that digital trade and information flows are becoming a more and more important source of our GDP."\nFor Cloud Service Providers, Snowden Fallout Reverberates\nFor a company such as Google, which has been one of the most vocal critics of the NSA's clandestine intelligence operations disclosed by Snowden, the international fallout has been severe.\nRichard Salgado, director of law enforcement and information security at the search giant, notes that several countries have responded to the Snowden revelations by enacting or considering data-localization laws, requiring cloud providers to store citizens' data within their national borders.\n"What's interesting about this is that the world of surveillance and the world of trade has now collided," Salgado says.\n[ More: U.S. Cloud Firms Face Backlash From NSA Spy Programs ]\nThe idea of concentrating data within a single physical facility, Salgado notes, runs counter to the distributed ethos of the cloud and undermines core benefits of the technology such as redundant storage and low latency rates for data movement.\n"All that is lost with data localization laws," he says. "The value of a cloud as we think about it is lost when you break it up into little pieces. You just have lots of sub-clouds."\nBliss ranks localization requirements "in various forms" as the top challenge \u2013 though by no means the only one \u2013 that U.S. trade negotiators face as they hammer out Internet issues in multilateral agreements with their counterparts.\nOther items on that agenda include online censorship and Internet freedom, protectionist policies that give a competitive advantage to local companies and interoperability barriers that can arise when countries insist that tech firms adhere to certain technical standards not broadly recognized in the international community.\n[ Opinion: Verizon's Not-So-Secret Plan to Kill Open Internet ]\nThose trade priorities certainly aim to protect the interests of U.S. tech firms. In a larger sense, too, they seek to combat what's sometimes described as the balkanization of the Internet \u2013 the concern that, added up, various nations' restrictive policies could have the effect of fragmenting the global network and the commercial activity it supports.\nDaniel Sepulveda, deputy assistant secretary of state and the department's coordinator for international communications and information policy, says administration officials work in their negotiations to convince their counterparts of "the value of the platform as a source for development for your entire economy," rather than opting for protectionist policies that narrowly aim to prop up local tech companies.\nSepulveda also touts what he describes as a thoroughgoing, independent review of government surveillance activities that Obama commissioned, along with reforms the president set in motion to limit data collection and beef up oversight of the intelligence community.\nData Localization Hurts More Than It Helps\nGoogle's Salgado argues that laws and policies that limit the cross-border flow of information often have the perverse effect of hurting the local economy by cutting off access to cloud services that could help businesses improve efficiencies and expand their market reach.\n[ News: Experts Worry Governments, 'Commercial Pressures' Will Undermine Online Freedom ]\n"There's an irony to it as well. There's a presumption \u2026 that data localization laws are good for the local country that's imposing them," he says. "What it overlooks is the fact that local businesses of all types actually take advantage of the services that are offered by cloud providers. An awful lot of companies use the services of Google and Amazon and Salesforce and lots of other companies out there to run their business."\nTo that end, Bliss says the U.S. Trade Representative's office is pressing partner nations to sign onto concrete language supporting cross-border data flows and rejecting server and data localization requirements, among other provisions, in the discussions over the Trans-Pacific Partnership, a massive trade deal the United States is negotiating with 11 other Asia-Pacific nations.\nSepulveda is quick to point out that the promotion of an open Internet is hardly a U.S. trade priority alone. Indeed, many policymakers around the world are warming to the potential economic benefit from a truly global cloud regime, where data can flow unimpeded across political borders.\nEarlier this year, for instance, Brazilian lawmakers pulled controversial language mandating foreign tech firms to store data locally from an Internet regulation bill, striking what Sepulveda sees as the "biggest localization threat" among recent policy proposals to come up for debate.\n"We're seeing that kind of educational process taking place around the world," he says. "There's a glass-half-full story to be told here. We're making some good and significant progress with our colleagues abroad."
