Nissan has warned that large falls on Chinese stock markets could negatively impact consumer confidence in the country.

Bloomberg reported that the company has said it is monitoring the situation following a large fall in equity prices over the past month that has led to suspensions of public offerings.

"If the rout is too abrupt, it leaves a negative impression on the economy, we will pay close attention to how it develops," Hiroto Saikawa, Nissan's chief competitive officer, told reporters in remarks reported by Bloomberg.

Over the past five years, share ownership in China has spread rapidly and recent reversals have grabbed headlines in China.

Consumer confidence is a key driver of new car sales. 

Retail deliveries of cars, multipurpose vehicles and sport-utility vehicles fell 3.2% in June from a year earlier, to 1.43m units.
