Nokia has confirmed that Liang Yumei, senior vice president for Greater China, South Korea and Japan, departed Nokia on June 1, 2011.

It is understood that the candidate to succeed Liang has not been determined; however, the business previously operated by Liang will be temporarily taken over by Colin Giles, Nokia's global head of sales.

Nokia did not reveal the reason for Liang's departure. But it is rumored that Nokia has been facing large pressure brought by Apple and Android-based mobile phones in the Chinese and global markets. The company's market share has been declining over the past two years. Nokia also admitted in its latest statistics published on April 21, 2011, that its sales share of mobile phone products decreased from 33% in the same period of last year to 29%. This is reportedly the first time for Nokia to see a market share lower than 30% in the worldwide market.

Stephen Elop, chief executive officer of Nokia Worldwide, said that Android's market share is quickly growing and with current products, it is hard for Nokia to compete with it. Due to management turnover and stock pressure, Nokia's business in China is facing large pressures.
