Rory Read, president and chief operating officer of Lenovo Group Ltd., China’s biggest maker of personal computers, talks about the company’s business strategy.   Lenovo said last month it offered to buy control of Germany’s Medion AG for 466 million euros ($671 million) in its biggest acquisition since the purchase of International Business Machines Corp.’s PC business more than six years ago. In January 2010, Lenovo paid $200 million to buy back Lenovo Mobile Communication Technology Ltd. after selling the unit in 2008. Read spoke to Bloomberg's Harsha Subramaniam yesterday in Mumbai.
