Cameron wants to restrict the currently free movement of labour to Britain from other EU countries.
Talking to media in Helsinki Friday, Cameron said "all countries around the table" were of the opinion that the issues should be reviewed. Finnish Prime Minister Alexander Stubb said that "if Britain has worries, we must listen", Xinhua reported.
Stubb described Britain as "the most international country" in the world and said that Britain should be given "a medal for opening its borders to EU immigrants in 2004".
Cameron maintained his criticism against a planned EU 2.1 billion euros (2.6 billion dollars) surcharge levied on Britain. He made a statement in October that he was not intending to pay the money in early December, and said that it "would not be right to pay such a sum."
