Prime Minister Stephen Harper said he is concerned about an influx of Czech asylum seekers to Canada and warned that he will act if the situation does not improve, the Agence France-Presse reported. Mr. Harper made the comments during a bilateral meeting with Czech Prime Minister Mirek Topolanek in Prague. The visit coincided with the Canada-EU Summit held on May 6. Czech Roma claim they are persecuted in their home country and have been seeking asylum in Canada since visa-restrictions on travel were lifted in October 2007. The number of Czechs making refugee claims in Canada reached 853 in 2008.
