The European Commission said it had started a preliminary investigation on concerns that the three companies could have abused their dominance by granting conditional rebates to retailers in some EU countries in order to block the entry of new drinks into the market.

It subsequently collected information from Coca-Cola and its bottlers, retailers and competitors.

"Based on the evidence collected, the Commission has concluded that there is insufficient ground to further pursue the investigation," the EU competition enforcer said in a statement.

"The closure of the investigation is not a finding that the conduct in question complies with EU competition rules," it said.
