China's state-owned Sinochem controls more than a third of Pirelli, one of the world's most recognized tire brands, and Italy just told it that control has limits. Now Sinochem is fighting back in court.

China National Tire and Rubber Corporation (CNRC), Sinochem's tire unit, along with its Milan-registered holding company Marco Polo International, filed separate appeals this week to an Italian regional administrative court. Their target: a government decree issued in April under Italy's "golden power" rules, which give Rome the authority to impose conditions on foreign investments in industries it considers strategically important. The two sides want the decree annulled entirely.

What Italy actually did

The April decree was pointed and specific. Italy cut the number of Pirelli board seats that Sinochem can fill to three, down from eight. That is not a procedural tweak. Moving from eight seats to three on a corporate board is the difference between shaping a company's direction and sitting on its sidelines.

The reason Italy gave was equally specific: the arrangement was designed to help Pirelli avoid running into U.S. restrictions. American rules limit business ties between companies on the U.S. market and firms connected to the Chinese state. Pirelli sells tires in the United States. With Sinochem holding eight board seats, that exposure was a real commercial problem.

So Italy used its golden power rules, a legal mechanism the country formalized and expanded after 2020, to restructure the ownership arrangement without forcing a sale.

Why Sinochem is pushing back

Sinochem through Marco Polo International holds 34.1% of Pirelli. That is a substantial financial stake, and under normal corporate logic a stake that size comes with governance weight. The April decree severs that link, giving Sinochem the economics of a major shareholder while trimming its political and strategic influence inside the company.

From Beijing's perspective, this is not just about one tire company. It is about whether European governments can systematically downgrade Chinese state ownership from "control" to "passive investment" using national security rules as cover. If the Italian court upholds the decree, it becomes a usable template. Other European governments watching Chinese state-linked firms accumulate stakes in their industrial champions now have a legal roadmap.

Pirelli said the legal challenge will not disrupt its shareholder meeting scheduled for June 25. That meeting will proceed. What it will not resolve is the deeper question of who actually runs one of Europe's most storied industrial brands.

The bigger pattern

This is one node in a much larger argument playing out across the Western world about what Chinese state ownership actually means inside a foreign company. The Chinese government does not own Sinochem the way a pension fund owns shares. Sinochem is a state enterprise, which means the line between commercial interest and state interest is genuinely blurred, at least from the perspective of governments in Rome, Brussels, and Washington.

Italy's golden power rules are part of a broader European shift toward investment screening that accelerated after several high-profile cases of Chinese firms acquiring sensitive industrial or infrastructure assets in the 2010s. The rules exist precisely because outright bans on foreign investment are legally and politically difficult, while doing nothing felt increasingly untenable.

The outcome of this appeal matters beyond Pirelli. A court ruling that the Italian government overstepped would weaken Rome's ability to use golden power rules in future cases and send a signal to Chinese state investors across Europe that legal challenges are worth pursuing. A ruling that upholds the decree would do the opposite, and would likely encourage other European governments to use similar tools more aggressively.

The June 25 shareholder meeting will come and go. The court case will take considerably longer, and its consequences will travel further.
