The 2012 G-20 Mexico Summit will be the seventh meeting of the G-20 heads of government. It will be held in Los Cabos, Baja California Sur, June 18-19 2012. The final draft of G20 Toronto summit communique became the public announcement that the 2012 summit would be hosted by Mexico.

Pre-planning for the summit began in 2010. In January, Mexican Deputy Foreign Minister Lourdes Aranda hosted a preliminary meeting in Mexico City. It was attended by "sherpas" (representatives) of the G20 foreign ministries.

Mexico believes the forum can better represent developing countries in both vision and policy. Under the leadership of President Felipe Calderón, Mexico will seek to expand the scope of the G-20's development focus.

Mexico (ⁱ/ˈmɛksɨkoʊ/; Spanish: México, IPA: [ˈmexiko] ( listen)), officially the United Mexican States (Spanish:  Estados Unidos Mexicanos (help·info)), is a federal constitutional republic in North America. It is bordered on the north by the United States of America; on the south and west by the Pacific Ocean; on the southeast by Guatemala, Belize, and the Caribbean Sea; and on the east by the Gulf of Mexico. Covering almost two million square kilometres (over 760,000 sq mi), Mexico is the fifth largest country in the Americas by total area and the thirteenth largest independent nation in the world. With an estimated population of over 113 million, it is the eleventh most populous country and the most populous Spanish-speaking country. Mexico is a federation comprising thirty-one states and a Federal District, the capital city.

In Pre-Columbian Mexico many cultures matured into advanced civilizations such as the Olmec, the Toltec, the Teotihuacan, the Zapotec, the Maya and the Aztec before the first contact with Europeans. In 1521, Spain conquered and colonized the territory from its base in México-Tenochtitlan, which was administered as the Viceroyalty of New Spain. This territory would eventually become Mexico as the colony's independence was recognized in 1821. The post-independence period was characterized by economic instability, the Mexican-American War and territorial cession to the United States, a civil war, two empires and a domestic dictatorship. The latter led to the Mexican Revolution in 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the country's current political system. Elections held in July 2000 marked the first time that an opposition party won the presidency from the Institutional Revolutionary Party.

On 20 September 2008, Thabo Mbeki announced his resignation after being recalled by the African National Congress's National Executive Committee, following a conclusion by Judge Nicholson of improper interference in the National Prosecuting Authority (NPA), including the prosecution of Jacob Zuma for corruption.

Zuma has faced significant legal challenges. He was charged with rape in 2005, but was acquitted. In addition, he fought a long legal battle over allegations of racketeering and corruption, resulting from his financial advisor Schabir Shaik's conviction for corruption and fraud. On 6 April 2009, the National Prosecuting Authority decided to drop the charges, citing political interference.
