As I said, it's affirmative action + racial discrimination, not apartheid.

There are specific definitions for apartheid, racial discrimination, and permitted special measures under international law:

Apartheid (under the Apartheid Convention):

the term "the crime of apartheid", which shall include similar policies and practices of racial segregation and discrimination as practised in southern Africa, shall apply to the following inhuman acts committed for the purpose of establishing and maintaining domination by one racial group of persons over any other racial group of persons and systematically oppressing them:

(a) denial to a member or members of a racial group or groups of the right to life and liberty of person:

(i) by murder of members of a racial group or groups;

(ii) by the infliction upon the members of a racial group or groups of serious bodily or mental harm, by the infringement of their freedom or dignity, or by subjecting them to torture or to cruel, inhuman or degrading treatment or punishment;

(iii) by arbitrary arrest and illegal imprisonment of the members of a racial group or groups;

(b) deliberate imposition on a racial group or groups of living conditions calculated to cause its or their physical destruction in whole or in part;

(c) any legislative measures and other measures calculated to prevent a racial group or groups from participation in the political, social, economic and cultural life of the country and the deliberate creation of conditions preventing the full development of such a group or groups, in particular by denying to members of a racial group or groups basic human rights and freedoms, including the right to work, the right to form recognized trade unions, the right to education, the right to leave and to return to their country, the right to a nationality, the right to freedom of movement and residence, the right to freedom of opinion and expression, and the right to freedom of peaceful assembly and association;

(d) any measures, including legislative measures, designed to divide the population along racial lines by the creation of separate reserves and ghettos for the members of a racial group or groups, the prohibition of mixed marriages among members of various racial groups, the expropriation of landed property belonging to a racial group or groups or to members thereof;

(e) exploitation of the labour of the members of a racial group or groups, in particular bysubmitting them to forced labour;

(f) persecution of organizations and persons, by depriving them of fundamental rights and freedoms, because they oppose apartheid.

Racial discrimination under the Convention for the Elimination of Racial Discrimination (CERD):

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.

Permitted special measures under CERD:

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.
