The Declaration of Windhoek, which defined the requirements for press freedom and pluralism in the media in Africa in 1991, constitutes an important milestone for these endeavours. In the following years, the principles of the Declaration of Windhoek were expanded to Asia, South America and the Arab world. In 1991, there was also the idea to declare 3 May as World Press Freedom Day . Since then, UNESCO has celebrated 3 May every year with a topical conference and awards the Guillermo Cano World Press Freedom Prize, which is named in honour of the assassinated Colombian journalist. The first laureates were journalists who were imprisoned while carrying out their work: Chinese journalist Gao Yu in 1997 and Nigerian journalist Christina Anyanwu in 1998. Both journalists were released soon after being awarded the prize. In 2007, the prize was awarded posthumously for the first time to the Russian journalist Anna Politkovskaya for her courageous reports on Chechnya.
