Trump threatens Section 301 probe as EU tech fines top ten billion dollars

When the European Commission announced a fresh $1 billion fine against Google in June, it brought the search giant's cumulative competition penalties in Europe to more than $10 billion. Three weeks later, Donald Trump posted on Truth Social that his administration would open a Section 301 investigation into what he called the EU's practice of "robbing" American companies. The move was not a surprise. It was the culmination of a dispute that has been building since the first Trump administration, paused under Joe Biden, and now revived with a specificity that suggests the next phase will be more than rhetorical.

The fines that triggered the threat

The Commission's case against Google centred on the company's abuse of its dominant position in online advertising technology. It is the third major competition decision against the company since 2017, following a €2.42 billion fine for shopping search, a €4.34 billion fine for Android, and a €1.49 billion fine for AdSense. Together they total roughly €9.2 billion. The latest penalty pushes the sum past the $10 billion mark when converted at current rates. Google has appealed each decision. The General Court has upheld some, reduced others, and the Court of Justice has yet to rule on the final appeals. What matters politically is the accumulation. In Washington, the total is read not as a series of independent legal judgments but as a revenue stream extracted from a single national champion.

Competition law is only one strand. A June 2025 report from Public Policy Solutions, a consultancy that works with technology clients, found that US-owned companies have absorbed 83% of all penalties imposed under the General Data Protection Regulation since it took effect in 2018. The report does not claim the enforcement is legally flawed. It argues the distribution reflects a structural bias: US firms process more European data at scale, so they appear more often in the dock. European data protection authorities reject that framing. They say the law is technology-neutral and the fines follow the violations. The numbers, however, are stark. Meta, Google and TikTok account for the largest single penalties. No European company has paid a fine above €50 million.

Digital services taxes and the GAFA label

The revenue argument extends to taxation. France was explicit when it introduced its digital services tax in 2019, naming it the "GAFA tax" after Google, Amazon, Facebook and Apple. Italy and Spain followed with similar levies. The three countries collected more than $1.2 billion from American companies in 2022 and 2023 alone, according to OECD data compiled by the US Trade Representative's office. The taxes apply to revenues generated from digital services where the user is located, a design that captures large foreign platforms while exempting most domestic firms below the €750 million global turnover threshold. The OECD's two-pillar solution was meant to replace these unilateral measures. Pillar One, which would reallocate taxing rights to market jurisdictions, has stalled. The unilateral taxes remain. The first Trump administration opened a Section 301 investigation in 2019, found the taxes discriminatory, and authorised tariffs. The Biden administration suspended them to make room for the OECD talks. That suspension is what Forbes and other critics cite as the moment Europe felt emboldened to go further.

The Digital Markets Act and the gatekeeper list

The Digital Markets Act entered into force in November 2022. It designates companies as gatekeepers if they meet thresholds for market capitalisation, user base and entrenchment across the EU. The first list, published in September 2023, named seven gatekeepers: Alphabet, Amazon, Apple, ByteDance, Meta, Microsoft and Samsung. Six are American. One is South Korean. None are European. The Commission says the thresholds are objective and the outcome reflects market reality. Critics say the thresholds were calibrated to capture the current incumbents, who happen to be American, while excluding European firms that operate in different sectors or at smaller scale. Every formal investigation opened under the DMA so far has targeted an American company: Google for self-preferencing in search, Meta for its "pay or consent" advertising model, Apple for App Store restrictions. The Commission has also launched a market investigation into Amazon Web Services and Microsoft Azure, even though neither met the ordinary gatekeeper thresholds for cloud services. That investigation uses a discretionary clause in the regulation.

The remedies are where the friction sharpens. The Commission has required Google to remove specialised search units from its general results, a change the company says degrades the user experience. Meta has been told to offer a non-personalised advertising option across its services. Apple must allow alternative app stores and payment systems on iOS. In each case, the company argues the remedy goes beyond what is necessary to restore competition and instead dictates product design. The Commission counters that the gatekeepers' scale makes traditional behavioural remedies ineffective. This is a genuine policy disagreement, not merely a trade grievance. But the coincidence of nationality has made it impossible to separate the two in Washington.

Sovereign cloud and procurement preferences

The latest front is public procurement. In March, the Commission awarded a €180 million contract for a European sovereign cloud infrastructure to a consortium of European providers, including OVHcloud, Deutsche Telekom and others. The contract is part of a broader "Tech Sovereignty" package that includes the European Chips Act, the European High Performance Computing Joint Undertaking, and a proposed Cyber Resilience Act. The language of the package repeatedly contrasts "foreign" dependencies with "European" alternatives. In practice, foreign means American. Only four of the world's 50 largest technology companies by market capitalisation are headquartered in Europe: ASML, SAP, Schneider Electric and Dassault Systèmes. None operates a hyperscale cloud. The Commission argues that strategic autonomy requires building capacity. The US side sees a closed market financed by European taxpayers to exclude American incumbents. Both descriptions are partially true.

Section 301: the tool and its history

Section 301 of the Trade Act of 1974 gives the USTR authority to respond to foreign practices that are unreasonable, discriminatory or burden US commerce. It was used heavily in the 1980s against Japan, then against the EU in the Airbus-Boeing dispute, and most recently against China. The process begins with an investigation, which can take months. If the USTR finds actionable practices, it can impose tariffs, restrict services access, or negotiate a settlement. The first Trump administration used it for the digital services taxes. The investigation concluded in December 2020 with a finding of discrimination and a list of $1.3 billion in proposed tariffs on French goods, including cosmetics and handbags. Those tariffs were suspended in January 2021. The Biden administration kept them suspended while the OECD negotiations continued. The OECD process has since stalled. The suspension remains. Trump's announcement last month was a signal that the suspension will not survive a second term.

Jamieson Greer, confirmed as USTR in February, told the Senate Finance Committee in his hearing that "the United States cannot let Europe control the global regulation of our companies." He did not specify which tools he would use. Section 301 is the most visible. Others include the International Emergency Economic Powers Act, which allows the president to regulate commerce in response to unusual threats, and the Foreign Investment Risk Review Modernisation Act, which screens inbound investment. The European Commission has said it will defend its laws at the WTO if the US imposes tariffs. A WTO dispute would take years. The practical effect of a Section 301 investigation is immediate: it creates uncertainty for European exporters and leverage for US negotiators.

The European defence: sovereignty and enforcement

Brussels does not accept the discrimination charge. The Commission's position, set out in multiple speeches by Margrethe Vestager during her tenure as competition commissioner and now by her successor Teresa Ribera, is that the EU enforces its laws against any company that breaks them. The fact that the largest digital platforms are American is a consequence of market history, not regulatory intent. The GDPR applies to any company processing European personal data. The DMA applies to any company meeting the gatekeeper thresholds. The digital services taxes apply to any company above the revenue thresholds. The sovereign cloud procurement follows EU public procurement rules, which allow preferences for security and strategic autonomy. European officials point out that US states and the federal government have their own procurement preferences, including Buy American provisions that are far more restrictive than anything in the EU treaties.

There is also a political dimension. The European Parliament, the Council and the Commission all campaigned on digital sovereignty in the 2024 elections. The legislation reflects a democratic mandate. When US officials object, European policy experts have reportedly replied that US companies "feeling the pain" proves the laws are working. That phrase, attributed to unnamed officials in the Forbes piece, captures the mood in parts of the European bureaucracy: a belief that the US has abdicated its own regulatory responsibility, leaving the EU to set global standards by default. The Brussels effect, as Columbia Law School professor Anu Bradford termed it, is real. US companies comply with EU rules because the European market is too large to ignore. That compliance then becomes the global baseline.

What the numbers actually show

The 83% GDPR figure is real but requires context. The regulation has issued over 2,000 fines since 2018. The vast majority are small, levied on small and medium enterprises across the EU. The large fines, the ones that move the aggregate, are concentrated on a handful of platforms that process the most data. Meta alone accounts for more than €2.5 billion in penalties. If you exclude the top ten fines, the US share drops sharply. The same pattern holds for competition law. The Commission has fined European companies for cartels in trucks, chemicals and financial services, totalling billions. But those cases are older and spread across many firms. The Google cases are recent, large and singular. The DMA gatekeeper list is a snapshot of a market that has not produced a European hyperscaler. That is a European industrial policy failure, not a regulatory conspiracy. But it is also a fact that the regulatory burden falls almost entirely on non-European firms.

What happens next

The USTR has not yet published a Federal Register notice initiating the investigation. That notice will define the scope: whether it covers only digital services taxes, or the full suite of DMA, DSA, GDPR and procurement measures. The broader the scope, the longer the investigation. Greer has indicated he wants to move quickly. The Commission will prepare a defence centred on the non-discriminatory text of its laws. The WTO will eventually be asked to rule, but not before the political damage is done. The next concrete milestone is the USTR's annual Special 301 report, due in April, which will signal the administration's priorities. Before that, the Commission's DMA compliance decisions on Google, Meta and Apple, expected in March, will test whether the remedies are calibrated or punitive. If the Commission forces structural changes that the US views as expropriation, the investigation becomes inevitable. If the remedies are behavioural and proportionate, there may be room for a negotiated de-escalation. The European Parliament's new term begins in September. The next Commission takes office in December. The window for a deal is narrow.
