"Because of its geographical proximity, the Busan plant is the site that is most exposed to supply disruptions in China," a Renault spokeswoman told Reuters.

She said Renault and its alliance partner Nissan were working closely on the supply disruptions as the Busan unit produces the Nissan Rogue SUV.

Renault extended on Monday the shutdown at its factory in China's Wuhan until Feb. 13, in line with the Chinese government's guidance following the coronavirus outbreak.

Fiat Chrysler warned on Thursday that supply disruptions due to the deadly virus outbreak could threaten production at one of its European plants within two to four weeks.
