Honda Motor Co said workers at a Chinese factory owned by unlisted affiliate Atsumitec Co have been on strike since July 12, with no resolution reached as of Thursday.

Japan's No.2 automaker, which has been plagued by supplier strikes since late May, said its four car plants in China were operating as usual with inventory. A spokeswoman in Tokyo said Atsumitec's factory, in Foshan, Guangdong province, supplies shift levers to Honda's local plants.
