Google Inc. completed its $12.5-billion purchase of Motorola Mobility, and the Web search leader named a new management team for the cellphone maker.

Google said on Tuesday that Motorola Chief Executive Sanjay Jha has stepped and has been succeeded by Dennis Woodside, former president of Google's Americas region. Woodside oversaw planning for the Motorola integration, according to Google.

The deal close comes just days after the companies gained approval for the acquisition from the Chinese government. European and U.S. regulators approved the deal in February.

Approval from Chinese regulators was slow in coming. On Saturday, China approved the deal, on condition that Google Inc.'s Android software would remain free for other phone makers for at least five years.

Google is buying Motorola, a pioneer in the cellphone industry, to prop up its patent portfolio and help defend phone makers who use Android against litigation.
