1. In this Convention, the term "racial discrimination" shall mean any distinction, exclusion, restriction or preference based on race, colour, descent, or national or ethnic origin which has the purpose or effect of nullifying or impairing the recognition, enjoyment or exercise, on an equal footing, of human rights and fundamental freedoms in the political, economic, social, cultural or any other field of public life.

2. This Convention shall not apply to distinctions, exclusions, restrictions or preferences made by a State Party to this Convention between citizens and non-citizens.

3. Nothing in this Convention may be interpreted as affecting in any way the legal provisions of States Parties concerning nationality, citizenship or naturalization, provided that such provisions do not discriminate against any particular nationality.

4. Special measures taken for the sole purpose of securing adequate advancement of certain racial or ethnic groups or individuals requiring such protection as may be necessary in order to ensure such groups or individuals equal enjoyment or exercise of human rights and fundamental freedoms shall not be deemed racial discrimination, provided, however, that such measures do not, as a consequence, lead to the maintenance of separate rights for different racial groups and that they shall not be continued after the objectives for which they were taken have been achieved.
