European Commission President Ursula von der Leyen on Monday tried to find common ground with Donald Trump by criticizing China’s export restrictions on raw materials used for cars, batteries and wind turbines.

During a session on the global economy at the G7 summit in Kananaskis, Canada, von der Leyen slammed Beijing for disrupting global trade by deploying subsidies to boost its own companies, according to an EU readout of the event. The chief of the EU executive accused China of “weaponizing” its leading position in producing and refining critical raw materials, and of ignoring global trade rules to undercut competitors.

Since April, Beijing has significantly restricted exports of permanent magnets and the minerals needed to make them. While that move came in response to Trump’s tariffs on China, Beijing has applied the restrictions globally, hurting Europe too.

“When we focus our attention on tariffs between partners, it diverts our energy from the real challenge — one that threatens us all,” von der Leyen said in a pointed comment aimed squarely at Trump, who sat near her at the G7 roundtable.

“On this point, Donald is right — there is a serious problem,” von der Leyen added, encouraging the U.S. president to join forces with his allies to address China’s trade imbalances, rather than impose tariffs on his allies.
