BEIJING - An increasing number of companies from emerging markets, led by China and India, have taken control of businesses in developed economies since 2002.

That's according to a recent study by the consulting firm, A.T. Kearney.

The number of cross-border merger and acquisitions (M&A) by businesses from emerging countries grew 26 percent in 2010, almost three times higher than the overall market for major M&A transactions.
