BRUSSELS (AP) — The European Union announced on Wednesday an investigation into whether China is using unfair methods to deprive companies in Europe of access to its market for medical devices ranging from hypodermic needles to high-tech scanners.

The probe launched by the European Commission — the EU’s executive branch as well as its trade and competition watchdog — is the latest attempt to help companies gain the kind of access to China’s vast markets that Chinese firms enjoy in Europe.

“Openness is vital for businesses to thrive, for consumers, and to spur innovation worldwide,” commission trade chief Valdis Dombrovskis said in a statement.

“We are launching this investigation with China so that we can achieve a level playing field in our procurement markets for producers of medical devices, on both sides,” he said. “Regrettably, our repeated discussions with China on this trade irritant have been fruitless.”
