Microsoft Corp met Wednesday with Japan's Fair Trade Commission officials to object to the planned tie-up between Yahoo Japan and Google Inc, the Nikkei business daily reported.
Microsoft expressed concerns about the deal from a competitive standpoint, citing how it will give Google nearly complete control over Japan's search services and related advertising, the paper said.
Last week, Microsoft said it planned to provide proof underscoring how the Google-Yahoo Japan partnership would be detrimental to competition, Nikkei said.
Yahoo Japan, Japan's largest Internet portal operator that currently uses Yahoo Inc's search technology, has confirmed with the Japanese government that the partnership with Google will not violate antitrust regulations.
The proposed deal between Google and Yahoo Japan -- an independent company in which Yahoo holds a 35 percent stake -- marks a divergence from the course set by Yahoo, which has forged a pact with Microsoft Corp for Web search technology.
