E/CN.4/1998/79 page 23 curbing all forms of discrimination is not only embodied in the Constitution but also reinforced by a broad range of supplementary legislation, and by systematic measures to promote equality of opportunity ensuring the effective enjoyment of the rights and guarantees proclaimed in that legislation. 87. “At the present time there remain in Cuba only a few isolated cases of racial prejudice which are manifested only in private family circles, and usually in relations between engaged couples or spouses and whose deep-rooted causes are of a historical and sociocultural nature, since the 37 years during which the policy to curb discrimination has been implemented are not enough to efface all secular stereotypes and the structure and interaction of the family do not change as rapidly as the legal and political measures adopted by the State. Nevertheless, these prejudices are not based on assumptions characteristic of racism as an ideology in other contexts, namely, the idea that there are innate differences between biological types.” This communication adds that “the other ethnic groups present in Cuba in the form of small communities or families account for less than 1 per cent of the population”. 88. This year the Cuban Government organized a national programme including numerous sociocultural events to commemorate the 150th anniversary of the arrival of the first Chinese in Cuba. 89. The Government has also reinstated human rights education: “As regards education as a means of preventing racism, civic education has been reinstated as a subject in the general education system starting from the academic year 1988-1989, and has continued to be improved; classes deal with human rights issues, especially the thrust of the Universal Declaration of Human Rights. Cuban history classes have also been reviewed, and the curriculum now includes teaching on the origins and ethno-racial interactions that led to the formation of the Cuban people and present-day Cuban nationhood ...”. Special Rapporteur's observations 90. The Special Rapporteur is glad of this highly informative news and welcomes the Cuban Government's endeavours in human rights education. He hopes to receive documentation on the situation and on current legislation pending an invitation from the Government to visit the country. (g) Paraguay 91. By communication dated 28 July 1997, the Government of Paraguay informed the Special Rapporteur that “not a single case of anti-Semitism, racial discrimination or racism affirming the superiority or privilege of one's own race by disdain for and persecution of others [was] to be found in Paraguay, particularly in reference to a numerically large minority or a minority with economic influence”. There was, on the other hand, “a certain indifference as of a spectator rather than participant”. The communication went on to state that the Chamber of Deputies had “by a large majority approved two draft statements rejecting and condemning the ill-treatment inflicted by Argentine gendarmes on Paraguayans and a xenophobic bill on migration currently before the Chamber of Deputies in the Argentine Congress”.
