The Congressional-Executive Commission on China was created by the U.S. Congress in 2000 "with the legislative mandate to monitor human rights and the development of the rule of law in China, and to submit an annual report to the President and the Congress. The Commission consists of nine Senators, nine Members of the House of Representatives, and five senior Administration officials appointed by the President." (CECC About). It tends to serve as an excellent barometer of the thinking of political and academic elite sin the United States about issues touching on China and the official American line developed in connection with those issues. As such it is an important source of information about the way official and academic sectors think about China. The CECC FAQs provide useful information about the CECC. See CECC Frequently Asked Questions. As one can imagine many of the positions of the CECC are critical of current Chinese policies and institutions.
CECC has recently focused on recent police and other actions in China, especially the detention of certain high profile lawyers (see here). It's leaders, including Marco Rubio, an individual seeking nomination to stand as the representative of the Republican Party for President, have now focused on the issue of religion in China. The CECC has announced plans to hold hearings on "Religion With “Chinese Characteristics”: Persecution and Control in Xi Jinping’s China." The hearings appear meant to suggest both that China has approached the issue of the relationship between religion and the state differently from the West, and that this difference ought to be troubling when it affects the ability of the institutional apparatus of religions to control their government. Whatever one thinks of the statement, it represents an important position of the United States with respect to these issues and is likely to figure in U.S. China relations going forward.
