American publishers are under US government sanctions not to publish works by foreign writers in certain countries. “In an apparent reversal of decades of U.S. practice, recent federal Office of Foreign Assets Control regulations bar American companies from publishing works by dissident writers in countries under sanction unless they first obtain U.S. government approval. The restriction, condemned by critics as a violation of the First Amendment, means that books and other works banned by some totalitarian regimes cannot be published freely in the United States.”
