Toyota Motor said its Chinese sales fell 6% in October to 61,600 vehicles, the first year on year decline in 18 months.

The decreasing popularity of Toyota cars and deteriorating Sino-Japanese relations have hit the company's sales in China, the Nikkei business daily reported, according to Reuters.

Robust demand in China, the world's biggest car market, has been one of the few bright spots for global automakers, and prolonged weak sales there could further hamper Toyota's profit recovery.

According to the Nikkei report, Corolla sales fell 16.4% to 33,700 vehicles despite a price cut, while Camry sales dropped 3% to 20,300 vehicles.
