The EU increased tariffs on Chinese-built EVs to as much as 45.3 percent but negotiations to avert them through price undertakings - minimum price commitments for imported cars

Maros Sefcovic, the European commissioner designate for trade, told a parliamentary committee that EU trade officials were in China for talks.

"What is very important for us is that even if you go (for price undertakings), they have to be equally effective and enforceable as the import duties we introduced. So that s absolutely key for us," he said.

Sefcovic is among 26 commissioners nominated by the EU executive s chief Ursula von der Leyen and undergoing hearings at the European Parliament this week and next. The next Commission needs parliamentary approval before it can start work.
