Rep. Chris Smith (R-N.J.), the author of the update to the original International Religious Freedom Act, also praised Tillerson for specifically recognizing the atrocities committed against minorities under Islamic State.
"I want to commend Secretary Tillerson for focusing on those who have been victims of genocide," he said. "These groups are looking for help and leadership, and I am proud that after eight years of denial and foot dragging, this report positions the United States to become a world leader in helping those who need it most."
Tillerson, in his remarks unveiling the report on Tuesday, also focused on the persecution of minorities in Iran, Saudi Arabia, Turkey, China, Pakistan, Sudan, and Bahrain.
In Iran, for instance, 20 persons were executed by the state in 2016 for apostasy charges including "waging war against God," he said. Baha'i leaders are still imprisoned for their religious beliefs in the country, where the state religion is Ja'afari Shia Islam.
In Turkey, religious minorities have seen their rights infringed upon by the government, which has also imprisoned Pastor Andrew Brunson who should be released, Tillerson said.
"Turkey continues to unjustly imprison Dr. Andrew Brunson without charges, and I appreciate Secretary Tillerson reminding the world of this. It is important for America to be clear about the human rights abuses happening around the world," Sen. Lankford (R-Okla.) said.
Tillerson also named Saudi Arabia as a violator of human rights and religious freedom, as punishments like prison and lashings are given to persons for charges of apostasy, atheism, blasphemy, and insulting the state's interpretation of Islam.
"We urge Saudi Arabia to embrace greater degrees of religious freedom for all of its citizens," Tillerson stated to the U.S. ally.
China is another well-known human rights violator, torturing and detaining thousands of citizens for their religious beliefs, including Uyghur Muslims and the members of Falun Gong, Tillerson said.
However, the secretary did not also mention that Christians are persecuted by the government there. State-sanctioned destruction of churches, or removing crosses from churches, has become commonplace in some provinces, and state officials have hampered parents from bringing their children to church.
In addition, the Vatican and the Chinese government have been working on an agreement on the appointment of bishops in the state-sanctioned Church, although critics like Cardinal Joseph Zen, the Archbishop Emeritus of Hong Kong, say the atheistic government will continue to meddle in the elections of bishops.

Smith said the report "rightly shows that China's religious freedom conditions are among the world's worst."
"The Chinese government is an equal opportunity abuser of the rights of Protestants, Catholics, Tibetan Buddhists, Uyghur Muslims and Falun Gong practitioners – all who face imprisonment and torture for practicing their faith," he said.
Calling the report "a step in the right direction," he also commended the reporting on other countries, such as Vietnam, Pakistan, Nigeria. and Syria, "with individuals who simply want to worship in peace being beaten, jailed, tortured or worse."
"The more difficult step will be to place these countries or non-state actors like ISIS and Boko Haram on the U.S. blacklist of severe religious freedom violators," he said.
This would include updating the "Countries of Particular Concern" list, which is comprised of countries the State Department deems where the worst violations of religious freedom are taking place and the government is either the instigator, actively complicit, or is powerless to stop the abuses.
The creation of the list was mandated by the International Religious Freedom Act as a way to hold violators of religious freedom accountable. Actions can be legally taken against such countries if the State Department places them on the CPC list, like imposing sanctions.
