The Chinese Communist Party (CCP) on Monday, July 13, announced the details of its retaliation measures against the United States after the Trump administration slapped penalties on CCP officials for their repression of Uighur Muslims and other minorities in the Xinjiang region.

The CCP’s Foreign Ministry said its sanctions targeted a trio of congressional Republicans, including Sens. Ted Cruz (R-Texas) and Marco Rubio (R-Fla.) and Rep. Chris Smith (R-N.J.), as well as Ambassador at Large for International Religious Freedom Sam Brownback and the U.S. Congressional-Executive Commission on China.

The Chinese Communist Party realized its promised retaliation after the Trump administration last week imposed sanctions on some Chinese senior officials in charge of the Xinjiang Uighur autonomous region who were “believed to be responsible for, or complicit in, the unjust detention or abuse of Uighurs, ethnic ­Kazakhs, and members of other minority groups in Xinjiang.”

In an announcement of the “corresponding sanctions” on Monday, Chinese Foreign Ministry spokeswoman Hua Chunying said that the behavior of U.S officials and politicians had severely damaged the relations between two countries and should be condemned.

The latest U.S. measures “seriously interfere in China’s [the CCP’s] internal affairs, seriously violate the basic norms of international relations, and seriously damage Sino-U.S. relations,” she said.

“Xinjiang is entirely the internal affair of China, and the U.S. has no right to interfere. The Chinese government’s [the CCP’s] determination to protect its sovereignty and crackdown against terrorism, separatism and extreme religious forces is unshakeable,” Hua said.

The spokeswoman also warned that the CCP would take further measures based on how the situation develops, the South China Morning Post reported.

The CCP hit back after U.S. Secretary of State Mike Pompeo announced last Thursday that the Trump administration would bar entry into the United States Chen Quanguo—the ­Xinjiang Communist Party secretary and a member of the Politburo—and three other senior officials from the region’s leadership, as well as its police department.

Pompeo said the sanctions were in line with the Global Magnitsky Human Rights Accountability Act, under which the United States can ­impose penalties on foreign ­officials for human rights abuses. The sanctions require all U.S. ­assets of the targeted individuals or entities to be blocked and reported to the Treasury Department’s office of foreign assets control.

Following Marxist atheism, Chinese Communist Party leaders have been seeking to eradicate faith believers, including Uighurs, Tibetans, Catholics, and Falun Gong. China’s suppression of Muslim Uighurs in the Xinjiang region has drawn international condemnation.

The United Nations has estimated that more than a million Muslims have been detained in camps there for political re-education, though the CCP claims they are vocational training centers aimed at countering religious extremism.

U.S. President Donald Trump in the middle of June signed an act which “holds accountable perpetrators of human rights violations and abuses such as the systematic use of indoctrination camps, forced labor, and intrusive surveillance to eradicate the ethnic identity and religious beliefs of Uighurs and other minorities in China.”
