of intellectual property, but the Committee on Economic, Social and Cultural Rights interprets it as primarily protecting the moral rights of authors and "proclaim[ing] the intrinsically personal character of every creation of the human mind and the ensuing durable link between creators and their creations". It thus requires parties to respect the right of authors to be recognised as the creator of a work. The material rights are interpreted as being part of the right to an adequate standard of living, and "need not extend over the entire lifespan of an author." Parties must also work to promote the conservation, development and diffusion of science and culture, "respect the freedom indispensable for scientific research and creative activity", and encourage international contacts and cooperation in these fields. Reservations A number of parties have made reservations and interpretative declarations to their application of the Covenant.Algeria interprets parts of Article 13, protecting the liberty of parents to freely choose or establish suitable educational institutions, so as not to "impair its right freely to organize its educational system."Bangladesh interprets the self-determination clause in Article 1 as applying in the historical context of colonialism. It also reserves the right to interpret the labour rights in Articles 7 and 8 and the non-discrimination clauses of Articles 2 and 3 within the context of its constitution and domestic law.Belgium interprets non-discrimination as to national origin as "not necessarily implying an obligation on States automatically to guarantee to foreigners the same rights as to their nationals. The term should be understood to refer to the elimination of any arbitrary behaviour but not of differences in treatment based on objective and reasonable considerations, in conformity with the principles prevailing in democratic societies."China restricts labour rights in Article 8 in a manner consistent with its constitution and domestic law.Egypt accepts the Covenant only to the extent it does not conflict with Islamic Sharia law. Sharia is "a primary source of legislation" under Article 2 of both the suspended 1973 Constitution and the 2011 Provisional Constitutional Declaration.France views the Covenant as subservient to the UN Charter. It also reserves the right to govern the access of aliens to employment, social security, and other benefits.India interprets the right of self-determination as applying "only to the peoples under foreign domination" and not to apply to peoples within sovereign nation-states. It also interprets the limitation of rights clause and the rights of equal opportunity
