Amnesty International recently published a report that claimed Qatar is still abusing migrant laborers in order to build the facilities that will be used to host the 2022 FIFA World Cup. The government of Qatar rejected the report and issued a statement saying that the report did not address the major reform Qatar's labor system has undergone. According to the government, Qatar has implemented a "wage protection system" and denies that its workers are being exploited.
