General Motors' China sales hit a record in September, the U.S. auto giant said Monday, amid a territorial row between Beijing and Tokyo that has reportedly hit the business of Japanese competitors.

GM's sales in the world's biggest car market reached 244,266 vehicles in September, rising 1.7% from the same month last year and jumping 10.5% from August, it said in a statement.

For the first nine months of the year, the company and its ventures sold nearly 2.1 million vehicles in China, up 10% from a year earlier.

Analysts said General Motors (IW 500/4) likely benefited from the territorial row between Japan and China which saw tens of thousands of Chinese protest in cities across the country, some urging a boycott of Japanese products.

Territorial Dispute Impacting Sales

"The Sino-Japan dispute... has affected Chinese consumers' purchasing choices to some extent," Haitong Securities analyst Zhang Qi told AFP.

"This has caused a negative impact for certain Japanese products, but in the meantime driven demand for other foreign car brands including those from the United States and Germany."

Sales of Toyota (IW 1000/8) cars in China plunged by 50% in September from August amid the anti-Japan backlash over disputed islands, Japan's Yomiuri newspaper said last week.

A festering row over the Senkaku islands in the East China Sea -- controlled by Japan but claimed by China, which knows them as the Diaoyu islands -- has affected Japanese automakers operating in the country.
