If the credibility of this anti-corruption drive is not to be undermined, the strictest guarantees of due process must be observed. 32. The Working Group was particularly struck by two government decisions intended to institutionalize these initiatives so as to make them effective in the long-term and to lay the foundations for a human rights culture in the State machinery: (a) One of these decisions was to establish, within the Ministry of Foreign Affairs, the Office of the Under-Secretary for Human Rights and Democracy to be responsible for “drawing up Mexico’s international policy in that area, coordinating the country’s participation in bilateral and multilateral forums and liasing with both national and international organizations from civil society”; (b) The other decision was to set up, in June 2002, the Inter-Ministerial Commission on Government Human Rights Policy, to be presided by the Minister of the Interior and consisting of representatives of the Attorney-General and the main ministries concerned and attended as an observer by the National Human Rights Commission.

Although the vast majority of these foreigners were from Central and South America, the Working Group observed significant numbers of Chinese nationals and nationals of Balkan countries. Citizens from Latin American countries usually stay in the migrant holding centre for a few weeks before being sent back to their country of origin. Nationals of countries in other regions tend to stay longer: some had
