Almost one third of Czechs dislike other races , particularly Roma, Germans and Vietnamese, according to an opinion poll released on Wendsday. The poll of 1,022 Czech men and women aged over 15 found that many believe foreigners are noisy , do not behave properly and are involved in crime. The survey , by the state-funded institutefor Public Opinion Research (IVVM) , asked Czechs about their personal feelings toward `` others ,`` but did not specifically ask about foreigners living in the Czech republic. It found that about 29 percent of Czechs disliked other races , with more than two thirds of that group feeling the most antipathy toward Roma. More than one quarter of those with antipathy toward non-Czechs said `` a more strict law on foreigners travelling and doing business`` in the Czech Republic should be adopted. Of those with anti-foreigner feelings , 10 percent felt most negative toward Germans , eight percent toward Vietnamese , five percent toward natives of the former Soviet Union , four percent toward Arabs, Moslems, Jews , and blacks. Two percent said they most disliked people from the Balkans and two percent disliked Slovaks , the Czechs former partners in the Czechoslovak federation. The Czech Republic still has a relatively homogeneous population , after the expulsion of millions of ethnic Germans following the end of Nazi occupation in 1945. But there has been an increase in immigration after 50 years of isolation under communism which ended in 1989 , and reports of racially-motivated attacks have increased.
