Lenovo adopted several strategies to maintain its leadership in the Chinese PC market and expand globally. It acquired IBM's PC division in 2004, gaining global market share, management skills, and ThinkPad/ThinkCentre brands. Lenovo also sponsored the 2006 Olympics and acquired European electronics firms Medion and CCE to strengthen its presence outside China. In China, Lenovo partnered with the government, avoided trade restrictions, offered competitive pricing and services, and catered to different customer segments. Going forward, Lenovo will focus on its "Protect and Attack" strategy through innovation, branding, and expanding beyond PCs into smartphones, tablets, and other connected devices. It faces challenges expanding further globally and competing against established players like HP and Dell
