Why would a multi-national corporation acquire a Chinese company? Because the Chinese market was too tempting. Lots of foreign corporations couldn't adapt to the environment in China, or compete with local companies. At times, acquisition became the most effective means to expansion.
For one thing, it could obtain the mature sales channel, market network, talent and client resources of the local company; for another, acquiring rivals helped annihilate them once and for all. Brands such as "Little Nurse", "Robust" and "Lekai Film" were prevalent several years ago, but now, they were nowhere to be found. What's more, buyout of the top firms in the industry led directly to monopoly.
