"As we outlined in August, the combination of Google and Motorola Mobility will help supercharge Android," he said.
"It will also enhance competition and offer consumers faster innovation, greater choice and wonderful user experiences."
The European Commission had originally intended to rule on the deal by 10 January but delayed its decision after requesting more information.
It wanted to examine whether Google might favour Motorola Mobility by making it harder for big-selling handset manufacturers, like Samsung or HTC, to use its Android operating system.
However, the commission concluded: "It is unlikely that Google would restrict the use of Android solely to Motorola, a minor player in the European Economic Area."
