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.
History of slavery
The 1926 Slavery Convention, an initiative of the League of Nations, was a turning point in banning global slavery. Article 4 of the Universal Declaration of Human Rights, adopted in 1948 by the UN General Assembly, explicitly banned slavery. The United Nations 1956 Supplementary Convention on the Abolition of Slavery was convened to outlaw and ban slavery worldwide, including child slavery. In December 1966, the UN General Assembly adopted the International Covenant on Civil and Political Rights, which was developed from the Universal Declaration of Human Rights. Article 4 of this international treaty bans slavery. The treaty came into force in March 1976 after it had been ratified by 35 nations.
