Background on Alicia Bárcena and Relevance

Alicia Bárcena, a former Mexican ambassador and undersecretary for multilateral affairs and human rights, was considered a strong candidate for the position of United Nations Secretary-General. Her extensive experience and diplomatic skills made her a prominent figure in Mexico’s international relations. However, despite initial support from the Mexican government led by President Claudia Sheinbaum, Bárcena’s candidacy ultimately fell short.

Mexico’s Diplomatic Challenges

The Mexican government, under President Andrés Manuel López Obrador, has prioritized aligning with like-minded Latin American governments. However, this strategy faced significant setbacks as Mexico’s diplomatic relations deteriorated. In 2018, Mexico had more allies than ideological opponents; today, the situation has reversed, with Mexico facing more opposition from ideological adversaries and having no diplomatic relations with Ecuador and Peru.

  • Mexico’s diplomatic strategy focused on supporting ideologically aligned Latin American governments.
  • The approach failed as Mexico’s number of allies dwindled, and its adversaries increased.
  • Currently, Mexico lacks diplomatic relations with Ecuador and Peru.

Mexico’s absence from the recent Foro Económico Internacional América Latina y el Caribe further highlighted its weakened regional presence. The event showcased Brazil and Chile’s active participation, while Mexico remained absent. This absence negatively impacted Bárcena’s chances of securing the UN Secretary-General position.

Internal Conflicts and Sabotage

Bárcena’s candidacy also faced obstacles from internal conflicts within Mexico’s foreign policy apparatus. The case of diplomat Martín Borrego, who married a Romanian diplomat in what was disguised as a bilateral relationship anniversary celebration, exemplifies these challenges.

  • Borrego’s personal event was intended to undermine Bárcena’s standing in foreign relations.
  • The event was recorded and used to sabotage Bárcena’s chances of becoming the UN Secretary-General.

Moreover, Bárcena’s relationship with key figures in Mexico’s foreign policy, such as Foreign Affairs Secretary Marcelo Ebrard and former ambassadors Juan de la Fuente and Roberto Velasco, reportedly suffered. These individuals did not support her candidacy, further weakening her position.
