Mobile phone manufacturer Motorola (MOT) has announced plans to cut 4000 more global jobs to improve its overall operation, and it says that Motorola China might be affected but that the number does not reflect China jobs.

It is still unclear how this will affect its operations in China. Yang Boning, director of Motorola China's Communications and Public Affairs Department, has told local media the staff reduction overseas is done to meet the need for business adjustment, which is imperative as a result of fierce competition, but he says Motorola China is committed to the China market for the long term.

Yang said the overall strategy of Motorola, including product combination and pricing rules, will be adjusted following the staff reduction, but the company's investment in China will be enlarged as China is still its important developing base.

Earlier this year, Motorola announced cuts of 3500 employees worldwide.
