The European Commission on Tuesday unveiled a new trade doctrine aimed at curbing China’s ability to squeeze Europe’s economy, and at preventing European companies from exporting sensitive, military-linked technology that could give China an edge.

The policy, still in its early stages, highlights how the European Union is seeking to align itself with the United States in limiting China’s access to sensitive markets and industrial secrets. It also reflects growing concerns about Beijing’s deepening alliance with Moscow.

The announcement in Brussels came in a busy week for Europe-China relations. The Chinese premier, Li Qiang, is visiting Germany, where he met with Chancellor Olaf Scholz and business leaders on Tuesday before heading to meetings in France.

The initiative also underscores how the European Union, one of the world’s biggest economies and a key trade partner to both China and the U.S., is trying to manage its economic dependence on Beijing and avoid the kind of economic breakup with Russia that followed the invasion of Ukraine.

The commission, the E.U.’s executive branch, said in a 14-page document that poor coordination among the member states and weak trade rules could allow adversaries to have an economic chokehold over E.U. economies or manufacturers, and needed to be urgently addressed.

“More than ever our national security is deeply intertwined with our ability to be economically safe and resilient,” the paper said.

The document didn’t once mention China, or any specific countries, but rather made reference to “destinations of concern that operate civil-military fusion strategies.”

Ursula von der Leyen, the president of the European Commission, said in comments to reporters that the policy was “country agnostic” and that it wasn’t aimed at overhauling how the bloc engages with economic powers. Rather, she said, “we’re looking at a limited, small set of cutting-edge technologies,” adding: “And here, we want to make sure that they do not enhance the military capacities of some countries of concern.”

But European diplomats said the proposed economic strategy was clearly about China. They said that it would probably take several months of debate before it becomes concrete policy, but that it was an essential first step toward preventing economic goals from undermining the European Union’s security.

Still, diplomats said that the bloc’s biggest economic powers — Germany, France, Italy and the Netherlands — were not eager for what could be disruptive intervention from Brussels in their critical economic relationships with China. Those concerns could set the scene for a watering-down of the commission’s proposals.

The bloc should keep potentially hostile countries and their companies out of certain critical infrastructure, such as ports and pipelines, and ban European Union companies from exporting high-tech goods with military uses to potential adversaries, the proposal said.

The document also aims to ensure that supply chains for security-sensitive goods are not overly dependent on such countries, and to stop proprietary European technologies in artificial intelligence, chip-making or biotechnology from “leaking.”

The bloc already has a set of rules in place that seeks to address some of these concerns, but the commission said that much better and stricter rules were needed, and that they should be applied with the same zest and standards across the 27 nations. The goal, the document said, is to make sure that there are no back doors to undermining European security.

“The need for more rapid and coordinated action at E.U. level in the area of export controls has become pressing,” the proposal said, noting that “an uncoordinated proliferation of national controls by Member States would create loopholes.”

Some European countries have already tightened their economic relations with China, with the Netherlands earlier this year banning the firm ASML from exporting its advanced chip production technology there on security grounds.

The bloc is also considering targeting Chinese companies with sanctions because they are providing Russia with chips used in weapons deployed against Ukraine.
