Microsoft has already won the support of Nokia’s shareholders, the E.U. commission, and the U.S. Department of Justice for its upcoming acquisition of Nokia. However, China still has concerns  and has launched a second probe into the deal, the emphasis of which is said to be antitrust. Local vendors are concerned that Nokia could become and “patent troll” and make life very difficult for them.

Earlier this year Microsoft announced that it will acquire Nokia’s devices and services division for $7.17 billion, pending shareholder and regulatory approval. Nokia’s shareholders voted overwhelmingly in support for this deal, and major regulatory bodies like the E.U. commission and the U.S. Department of Justice all gave their blessing as well. However, China’s Ministry of Commerce launched a probe into the deal and it appears that the authorities aren’t done yet. Rumor has it that another probe into this deal has been launched, fueled by concerns voiced by local manufacturers in the country.
