"We have taken note of the FTC ( Federal Trade Commission) decision, but we don't see that it has any direct implications for our investigation, for our discussions with Google, which are ongoing," said Michael Jennings, a spokesman for the European Commission.
US regulators yesterday ended their investigation into the giant internet company, which runs the world's most popular search engine.
Other internet companies, such as Microsoft, had complained about Google tweaking its search results to give prominence to its own products. But the FTC said there was not enough evidence to pursue a big search-bias case.
The European Commission has for the past two years been investigating complaints against Google, including claims that it unfairly favoured its own services in its search results.
Google presented informal settlement proposals to the EC in July. On December 18 the Commission gave the company a month to come up with detailed proposals to resolve the investigation.
If it fails to address the complaints and is found guilty, Google could eventually be fined up to 10pc of its revenue - a fine of up to €3bn.
