International PEN, the worldwide association of writers, exists to promote friendship and intellectual co-operation among writers everywhere, regardless of their political or other views; to fight for freedom of expression and to defend vigorously writers suffering from oppressive regimes. PEN is strictly non-political, a Non Governmental Organization with Category A status at UNESCO. It is composed of Centres, each of which represents its membership and not its country. Membership is open to all qualified writers, regardless of nationality, language, race, colour or religion, and every member is required to sign the PEN Charter and by so doing to observe its conditions.
