BEIJING - China's top oil refiner, China Petrochemical Corporation (Sinopec), on Tuesday denied media reports that it is bring nearly 40 percent of staff of its global unit back to China.

The reports were inaccurate, Sinopec spokesman Lyu Dapeng said.

The total number of Chinese staff in Sinopec's global exploration and production unit, also its wholly-owned subsidiary, Sinopec International Petroleum Exploration and Production Corporation (SIPC), are only around 700, and 263 of them will be relocated back to China's offices, under the company's regular job rotation system, Lyu said.

The staff mobility will optimize the company's human resources, and improve the management quality and operation efficiency, Lyu said, adding that more than 80 percent of all the employees in the SIPC are non-Chinese.
