The main purpose of the Tibet Atrocities Determination Act is to require the U.S. Secretary of State to assess whether the actions of the Chinese government against the Tibetan people amount to genocide or crimes against humanity. This legislation aims to bring attention to the situation in Tibet and to hold the Chinese government accountable for its treatment of Tibetans. Key provisions of the Act include a mandate for the Secretary of State to complete this determination within one year of the law's enactment.
