BYD has become a relentless discounter in the price war that Tesla started in the world's largest auto market last year. That aggressive stance has helped it unseat its U.S. rival as the world's biggest seller of electric vehicles, even though most of BYD's cars are sold in China.

BYD Co. has asked suppliers to accept price cuts next year in a signal the Chinese electric vehicle maker is preparing for the brutal price war in the world’s biggest auto market to intensify.

An executive from BYD said on Wednesday the Chinese automaker sets price reduction targets for suppliers when making large-scale purchases but these are negotiable and not mandatory. The comments from Brand and Public Relations Department general manager Li Yunfei on his Weibo account followed reports the Chinese automaker had told a supplier to cut prices by 10%.
