With Nikita Khrushchev's repudiation of Stalin's practices in the "Secret Speech" and the Communist Party of China's repudiation of certain Maoist policies, Marxist–Leninist legal theories began to emphasise "the formal, formerly neglected constitutional order." Deng Xiaoping, not long after Chairman Mao Zedong 's death, noted that "has to be institutionalised and written into law, so as to make sure that institutions and laws do not change whenever the leadership changes or whenever the leaders change their views. [... The trouble now is that our legal system is incomplete. [...] Very often what leaders say is taken as law and anyone who disagrees is called a lawbreaker." In 1986, Li Buyan wrote that "the policies of the Party usually are regulations and calls which to a certain extent are only principles. The law is different; it is rigorously standardised. It explicitly and concretely stipulates what the people should, can or cannot do." These legal developments have been echoed in later years in Cuba, Laos and Vietnam. This has led to the development of the communist concept of socialist rule of law which runs parallel to and is distinct to the liberal term of the same name. In the last years, this emphasis on the constitution as both a legal document and a paper which documents society's development has been noted by Chinese Communist Party general secretary Xi Jinping, who stated in 2013 that "o organisation or individual has the privilege to overstep the Constitution and law."
