Workers at a factory in southern China's Guangdong Province making car locks for Honda Motor returned to work Tuesday, ending a six-day strike, local government said.

But pay-rise negotiations continue as workers have not agreed to the company's offer of a 100 yuan (14.6 U.S. dollars) per month rise in basic salary and an over-time pay raise of 50 yuan per day, the Xiaolan Township local government said.

The workers have demanded a 300 yuan increase in monthly basic salary.

The company has offered a 100-yuan rise in allowances, but workers said the company must specify the kind of allowance to be raised as some allowances are only paid a few months per year.

Workers expect the factory to give a clear response to their demands within three days, Lin Wenping, a workers' representative, told Xinhua Tuesday.

Lin said negotiations over the next three days will be "critical." He did not say what would happen if the two sides failed to reach an agreement.

About two thirds of the factory's 1,500 employees went on strike. The factory has 300 managers and 1200 workers.

The Honda lock factory is a joint venture between the Japanese firm and a local company affiliated with the Xiaolan township government. It makes locks and key sets for Honda auto assembly plants.

The strike was the third to hit Honda-related factories in Guangdong in less than a month. Workers at two other factories received significant pay increases after going on strike.
