Freedom of association is strictly controlled by the authorities, despite conditional constitutional protection of this right. Organisations whose activities are considered uncontroversial and non-political – such as those providing services to alleviate poverty – are generally allowed to operate freely. However, other organisations, in particular those which work on civil and political rights, routinely face threats and intimidation, the imposition of arbitrary and unreasonable requirements, raids and shut-downs, and the arbitrary arrest and detention of members. Independent labour unions are outlawed.
