Decades of U.S. intervention in its "backyard" Latin America directly led to the worsening of the immigration problems in the Americas, according to the Record of Human Rights Violations in the United States in 2019.
The report was issued by the State Council Information Office on Friday.
In recent years, the U.S. government had adopted increasingly strict and inhumane measures against immigrants, in particular the "zero-tolerance" policy which caused the separations of many immigrant families, the report read.
Many unaccompanied immigrant children were held in overcrowded facilities, without access to adequate healthcare or food, and with poor sanitation conditions, the report said.
It noted grave abuses at detention facilities for immigrants, including injecting them with sedatives, keeping them in handcuffs and depriving them of clothing and mattresses.
The frequent human rights violations of immigrants by the United States have been severely condemned by the international community, the report added.
