P. C. Chang
On the Universal Declaration of Human Rights drafting committee, he served both as an effective Asian delegate and also as a mediator when the negotiations reached a stalemate. He served as Vice-Chairman of the original UN Commission on Human Rights and Republic of China delegate to committee and played a pivotal role in its drafting of the Universal Declaration of Human Rights (UDHR) of 1948. He and fellow delegate Charles Malik, the Lebanese philosopher-diplomat, shared ideals of universal human rights, but debated what they were and how they could be described in an international document. By most accounts, Chang and Malik were the philosophical leaders of the deliberations. Chang argued that the modern world should pay heed to Chinese philosophers such as Mencius not because they were Chinese, but because their ideas had universal validity.
Reproductive rights
In 1945, the United Nations Charter included the obligation "to promote... universal respect for, and observance of, human rights and fundamental freedoms for all without discrimination as to race, sex, language, or religion". However, the Charter did not define these rights. Three years later, the UN adopted the Universal Declaration of Human Rights (UDHR), the first international legal document to delineate human rights; the UDHR does not mention reproductive rights. Reproductive rights began to appear as a subset of human rights in the 1968 Proclamation of Tehran, which states: "Parents have a basic human right to determine freely and responsibly the number and the spacing of their children".
