An internal State Department cable dated Feb. 18 and signed by Secretary of State Marco Rubio is telling U.S. diplomats to push back on foreign "data sovereignty" and data localization rules, casting them as a threat to the cross-border data flows that fuel cloud services and many AI systems. The move immediately raised concerns among privacy advocates and technology companies that depend on international data-sharing networks.
According to Reuters, the cable warned that such laws would "disrupt global data flows" and urged U.S. posts to "counter unnecessarily burdensome regulations, such as data localization mandates." The memo framed the campaign as part of a push for a "more assertive international data policy" and explicitly labeled the message an "action request." Reuters reported that the directive also arms diplomats with talking points that promote a voluntary cross-border privacy forum as a preferred alternative.
The cable highlighted geopolitical stakes as well, saying China is "bundling enticing technology infrastructure projects with restrictive data policies" to gain influence and access to foreign data, language that links infrastructure deals to surveillance and strategic leverage. TechCrunch noted that the administration has framed the push as a way to protect U.S. leadership in AI. The Chinese Embassy in Washington told reporters it was not familiar with the cable and said Beijing "has always attached great importance to cybersecurity and data security," according to coverage of the reporting.
What Diplomats Were Asked to Do
The cable, whose headline described it as an "action request," tasked U.S. posts with tracking proposals that would restrict cross-border data flows and with promoting the Global Cross-Border Privacy Rules framework as an alternative. As laid out by the U.S. Department of Commerce, the Global CBPR Forum, established in 2022, is a voluntary certification system designed to ease international data transfers while promoting accountable privacy practices.
State Department materials cited in the reporting instructed diplomats to stress that data localization can raise costs, increase cybersecurity complexity and limit access to cloud and AI services. In other words, embassies are being asked to quietly lobby foreign governments toward a more open data regime while holding up CBPR as the “responsible” middle ground.
Why Silicon Valley Should Pay Attention
Data localization laws can force companies to build and maintain duplicate data centers in multiple regions, driving up infrastructure costs for startups and cloud providers and complicating global product rollouts. The European Union's European Union General Data Protection Regulation, which took effect in 2018, already imposes strict rules on transfers of Europeans' data and has required large compliance investments from U.S. firms.
For AI developers that depend on large, diverse datasets, restrictions on moving data across borders can slow training cycles and increase operational fragmentation. That combination, companies warn, can make it harder to run a single, coherent global service rather than a patchwork of region-specific systems.
Political Flashpoint
The Feb. 18 memo fits a broader pattern of using diplomatic channels to shape foreign tech rules. Last year, a State Department cable instructed posts to campaign against the European Union's Digital Services Act, a push first reported in August 2025. Those earlier instructions heightened transatlantic tensions over how to balance content moderation, speech and the regulatory burden on U.S. platforms.
Critics say the new directive risks widening the gap between U.S. trade and national-security priorities on one side and European regulators' focus on privacy and platform responsibility on the other. Industry groups and European officials are expected to debate whether to resist the U.S. effort outright, negotiate carve-outs, or speed up work on alternative certification and interoperability schemes.
For now, the State Department has not released the full cable text and has not publicly issued a detailed response to media questions, leaving the exact diplomatic follow-through, and any allied pushback, to play out in the coming weeks.
