The People's Republic of China is a signatory to the International Covenant on Civil and Political Rights, but has not ratified it. Legally, all citizens of the People's Republic of China who have reached the age of 18 have the right to vote and stand for election, regardless of ethnicity, race, sex, occupation, family background, religious belief, education, property status, or length of residence, except for persons deprived of political rights according to laws imposed by the CCP's Constitution.

In Mao's China, the CCP openly repressed all opposing political groups. This behaviour is now reflected in the judicial system, and has evolved into the selective repression of small groups of people who overtly challenge the CCP's power or its people's democratic dictatorship. The most recent major movement advocating for political freedom was obliterated through the Tiananmen Square Massacre in 1989, the estimated death toll of which ranges from about 200 to 10,000 depending on sources. In November 1992, 192 Chinese political activists and democracy advocates submitted a petition to the 16th National Congress of the Chinese Communist Party to introduce political reforms. One of the six demands was the ratification of the Covenant. As a reaction to the petition, the Chinese authorities arrested Zhao Changqing, proponent of the petition, and are still holding a number of activists for attempted subversion.

One of the most famous dissidents is Zhang Zhixin, who is known for standing up against the ultra-left.

In October 2008, the government denounced the European Parliament's decision to award the Sakharov Prize for Freedom of Thought to political prisoner Hu Jia, maintaining that it was 'gross interference in China's domestic affairs' to give such an award to a 'jailed criminal.. in disregard of [the Chinese government's] repeated representations.'

Although the Chinese government does not violate its people's privacy as much or as overtly as it used to, it still deems it necessary to keep track of what people say in public. Internet forums are strictly monitored, as are international postal mail (which sometimes is inexplicably delayed, or simply disappears) and e-mail.

Local officials are chosen by election, and even though non-Communist Party candidates are allowed to stand, those with dissident views can face arbitrary exclusion from the ballot, interference with campaigning, and even detention.

Freedom House rates China as a 6 (the second lowest possible rank) in political freedoms. In 2011, the organization said of the Chinese political leadership:

With a sensitive change of leadership approaching in 2012 and popular uprisings against authoritarian regimes occurring across the Middle East, the ruling Chinese Communist Party showed no signs of loosening its grip on power in 2011. Despite minor legal improvements regarding the death penalty and urban property confiscation, the government stalled or even reversed previous reforms related to the rule of law, while security forces resorted to extralegal forms of repression. Growing public frustration over corruption and injustice fueled tens of thousands of protests and several large outbursts of online criticism during the year. The party responded by committing more resources to internal security forces and intelligence agencies, engaging in the systematic enforced disappearance of dozens of human rights lawyers and bloggers, and enhancing controls over online social media.

Jiang Tianyong is the latest lawyer known for defending jailed critics of the government. In the 709 crackdown which began in 2015, more than 200 lawyers, legal assistants, and activists, including Jiang, were arrested and/or detained.
