Mexico as a founding member of the United Nations.
On 26 June, 1945, Mexico was represented in San Francisco by Ezequiel Padilla Peñaloza, Francisco Castillo Nájera and Manuel Tello Baurraud in the signing of the United Nations Charter. The country was formally admitted into the organization on 7 November, 1945. Since the beginning, Mexico has participated actively in the social and economic activities of the UN's various specialized agencies and other international organizations concerned with social, cultural, and economic improvement. However, due to restraints in the Mexican constitution, Mexico is prohibited from contributing troops for peacekeeping missions abroad unless Mexico has formally declared war on a country. Calls have been made from Mexican politicians to amend the constitution in order to partake in UN peacekeeping missions.
Mexico has been elected four times to the United Nations Security Council. The Mexican Government is vehemently opposed to adding new members to the Security Council. Mexico and eight other countries created a group called the "Uniting for Consensus" (also known as the Coffee Club), where they are opposed to new permanent members, however they would like to raise the number of more non-permanent members to 20.
