China's quality inspection agency has halted the import of several models made by Renault, citing serious safety risks and a failure to meet technical standards.
The General Administration of Quality Supervision Inspection and Quarantine (AQSIQ) said the ban applied to the Renault Laguna, Scenic, Megane and Megane Coupe-Cabriolet.
A statement on the AQSIQ website read: "In recent import inspections, we have repeatedly found batches of passenger vehicles made by the French Renault ... do not conform with our country's mandatory standards and relevant technical regulations, and there are serious safety risks."
It added that, in the past year, Renault cars "have many times revealed quality problems."
The statement, however, did not specify what safety problems it had identified.
China is the world's largest market for new car sales, although Renault report sales of less than 1000 cars there in 2008.
All four cars cited by AQSIQ has earned five Euro NCAP stars in crash tests.
