BRUSSELS: The European Union is enforcing tariffs on $3.4 billion in US products as of Friday in retaliation to duties the Trump administration has put on European steel and aluminum.
The goods targeted include typical American products like bourbon, peanut butter, and orange juice, in a way that seems designed to create political pressure on US President Donald Trump and senior US politicians.
"This response by the European Union is adequate, it is proportionate and it is reasonable. Needless to say, it is in full respect of EU and WTO rules," European Commission Alexander Winterstein.
Trump imposed tariffs of 25 percent on EU steel and 10 percent on aluminum on June 1. Europeans claim that breaks global trade rules.
The spat is part of a wider tussle over global trade. In two weeks, the United States will start taxing $34 billion in Chinese goods. Beijing has vowed to immediately retaliate with its own tariffs on US soybeans and other farm products.
Customs agents across Europe’s colossal market of 500 million people will now impose the duty, hiking prices on US-made products in supermarkets and across factory floors.
“These measures are the logical consequence of the US decision,” French Finance Minister Bruno Le Maire said.
“They reflect a Europe that is resolute and principled,” he said.
EU Trade Commissioner Cecilia Malmstrom said this week that the 28-nation bloc was “left with no other choice” but to impose tariffs of its own after the “unilateral and unjustified decision of the US.”
Together with US tariffs against Mexico and Canada, the trade battles have raised the spectre of a global trade war, spooking financial markets that fear major consequences to the global economy.
“We have a trade war — and it’s an escalating trade war,” SEB chief economist Robert Bergqvist said in an interview.
Brussels first drew up the list in March when Trump initially floated the 25 percent tariffs on steel imports and 10 percent on aluminum, which also target Canada, Mexico and other close allies.
The list does not specifically name brands but European Commission chief Jean-Claude Juncker spelled out in March that the bloc would target “Harley-Davidson, bourbon and Levi’s jeans.”
Cranberries, cranberry juice, orange juice, sweetcorn and peanut butter are among the other food products targeted.
Juncker said on Thursday that the US decision to impose tariffs “goes against all logic and history.”
“Our response must be clear but measured. We will do what we have to do to rebalance and safeguard,” he said.
European consumers would be able to find “alternatives,” European Commission Vice President for trade Jyrki Katainen said.
“If we chose products like Harley Davidson, peanut butter and bourbon, it’s because there are alternatives on the market. We don’t want to do anything that would harm consumers,” he said on Thursday.
“What’s more, these products will have a strong symbolic political impact.”
International Monetary Fund (IMF) chief Christine Lagarde warned on Thursday that trade war, as well as Brexit, were the key risks to the eurozone economy.
While she didn’t see a serious “direct impact of tariff increases... it’s a trend that is worrying, the breach of confidence that undermines confidence,” she said on the sidelines of eurozone minister talks in Luxembourg.
Transatlantic ties are at their lowest level for many years due to rows over a host of issues including the Paris climate agreement and the Iran nuclear deal.
Relations plumbed new depths at the recent G7 summit when Trump abruptly rejected the joint statement and bitterly insulted his Canadian host, Prime Minister Justin Trudeau.
Trump claimed America had been obliged to levy the metals tariffs as it has been exploited as the world’s “piggy bank.” He is also targeting EU auto imports with a US probe now underway.
Trump’s outbursts were the latest in which he has clashed with America’s closest allies, even as he has had warm words for autocrats like North Korean leader Kim Jong Un, with whom he had a historic meeting earlier this month, and Russia’s Vladimir Putin.
But US Assistant Secretary of State for European and Eurasian affairs Wess Mitchell said on Thursday that Trump’s approach toward his allies was about “strategic renovation.”
“Strengthening the West means making hard decisions today when we initially disagree, rather than continuing to accept the appearance of transatlantic unity,” he told the Carnegie Europe think-tank in Brussels.

The hidden side of clean power: why grid integration matters
- Exploring the predator’s role in the region’s heritage and ecosystem
RIYADH: As Saudi Arabia expands solar, wind, and battery projects, a critical piece of the sustainability puzzle often goes unseen: grid integration.
Before renewable plants can deliver power, engineers must ensure the grid remains stable, safe, and efficient under new loads. Integrating renewables into existing systems has become one of the toughest — and most crucial — steps toward building a truly sustainable energy network.
Engineers widely consider the electricity grid the largest and most complex machine ever built. As more renewable capacity comes online, managing it is becoming as much a data challenge as an energy one.
“A big share of Saudi Arabia’s electricity is generated from renewables and more projects are connected to the grid each year. This shift changes how the electricity grid is managed on a day-to-day basis,” Saeed Al-Zahrani, general manager of data enterprise storage leader NetApp in Saudi Arabia, told Arab News.
“To add context, traditional generation can usually be adjusted in a controlled way. Wind and solar, however, move with conditions such as cloud cover, dust, temperature and wind speed, meaning supply can rise and fall quickly,” he said.
In this environment, grid integration is less about whether enough electricity can be produced and more about whether operators can see and respond to changes across the network fast enough to maintain stability.
Frequency, voltage, congestion, and reserve margins all become more dynamic. Real-time measurements, accurate forecasting, asset status updates, and weather intelligence must come together into a reliable, unified system view.
“From NetApp’s perspective, this is where the data foundation matters most, because the grid can only act confidently when the information behind the decisions is timely, governed, and reliable,” Al-Zahrani said.
Under Vision 2030, Saudi Arabia aims to generate 50 percent of its energy from renewables — an ambitious target that introduces new technical and operational challenges. Weather variability, cyber threats, and system coordination can all affect grid stability.
“Every device that operates under this control regime that’s connected to the grid is digital nowadays. You have smart inverters, you have sensors, you have energy management systems, and all those devices and systems are potential entry points for attackers,” Charalambos Konstantinou, a professor at KAUST, told Arab News.
His lab focuses on maintaining reliable and secure power infrastructure, developing faster and smarter control algorithms capable of responding to sudden changes in the power system.
“This is what we’re working to make sure that those algorithms remain robust. They remain resilient. They remain secure, even if something, maybe an extreme weather event, or a cyber attack, is aiming to disrupt them,” he said.
Rapid digitalization, however, can create vulnerabilities if security measures do not keep pace. In 2012, Aramco experienced the Shamoon attack, a computer virus that affected around 30,000 workstations.
“When you scale fast, security practices typically lack behind deployment, and this is essentially what we focus a lot in my group: making sure that internet-connected or digital devices cannot be used as an entry point to destabilizing the grid,” Konstantinou said.
One particularly concerning threat involves load-altering attacks, which can disrupt power systems without requiring deep penetration of the grid itself.
“If an attacker is able to control a large amount of what we call internet connected high voltage devices — think HVAC systems, air conditioning systems, water heaters, electric vehicle chargers — and is able to switch them on and off at the same time, simultaneously, then he or she can create a certain imbalance between generation and demand, and then the grid (becomes) very difficult to handle,” he said.
Such disruptions could potentially trigger widespread blackouts.
Beyond cybersecurity risks, the physical environment also presents challenges. Saudi Arabia’s relatively consistent weather can be an advantage for renewable energy production, but factors such as dust accumulation on solar panels and thermal stress on inverters can still affect performance.
Testing technologies under local conditions — including extreme heat, network behavior, and the mix of generation assets — is essential before large-scale deployment. Equally important are intelligent coordination frameworks that allow flexible energy assets to work together while optimizing energy use across industries.
Renewable-heavy grids across Saudi Arabia and neighboring countries increasingly depend on real-time data from SCADA systems, substation automation, and weather monitoring to balance supply and demand. While these continuous data flows improve efficiency, they also introduce new risks, including potential system disruption and data manipulation.
Vasily Dyagilev, regional director for the Middle East, Russia and CIS at Check Point Software Technologies Ltd., highlighted the scale of these vulnerabilities.
“In Saudi Arabia, 58 percent of organizations have experienced information disclosure vulnerabilities, while remote code execution and authentication bypass remain significant threats. The complexity of managing legacy operational technology networks alongside modern cloud-based systems and third-party integrations makes it difficult for utilities to maintain full visibility over their risk landscape.
“The region has also seen high-profile incidents where attacks on SCADA systems led to operational disruptions, highlighting the fragility of critical infrastructure. Effective exposure management, including continuous vulnerability discovery and prioritized remediation based on operational risk, is now recognized as essential for maintaining grid stability and protecting the integrity of real-time data streams.”
Alongside cyber and operational risks, uncertainty in weather patterns remains a key variable in renewable power generation.
Omar Knio, another professor at KAUST, studies how atmospheric processes influence renewable energy systems through uncertainty quantification and climate modeling. Dust particles originating in the Arabian Peninsula, for instance, can travel thousands of kilometers and influence weather patterns across South Asia.

“Phenomena at tiny little scales end up, through teleconnections, making very important contributions to weather patterns and to the climate as far as renewables themselves, because these phenomena affect the solar and wind potentials, they’re extremely important to predict accurately,” Knio said.
“The presence of dust in the atmosphere and cloud cover affect the output of solar panels or solar plants, and similar phenomena happen to wind, and that's why they are really challenging. It's important to be able to predict them as accurately as we can.”
Maintaining a stable renewable grid requires both short-term and long-term forecasting. Hourly predictions are essential for balancing supply and demand, while longer-term projections help planners prepare infrastructure and storage.
Artificial intelligence is increasingly helping researchers build models that forecast weather patterns, simulate thermal behavior in buildings, and analyze industrial energy use. In areas where detailed physical models are limited, AI also helps uncover patterns in human behavior and electricity consumption.
“An example is power demand, consumer behavior, or changes in patterns that have to do with the day of the week, whether it's a weekend, a holiday season, whether it's during harsh weather, or it's during Ramadan: how do these patterns change? And artificial intelligence is really bringing the capability for us to represent and forecast these very complex phenomena,” Knio said.
As renewable energy penetration approaches higher levels, the system becomes more sensitive to fluctuations and extreme events.
“There comes a point where we start having a very dramatic rise in the need for storage capabilities. And the important aspect of why our fuel is important. We can make them cleaner, but they’re wonderful in the sense that they are plentiful right now. They are cheap, but more importantly, they are quite economical to store after. After fuels come nuclear power. So it’s really that storage capability. As we approach 100 percent, the need for storage becomes extremely heightened,” Knio said.
