Top stories this week are likely to include: Calderón and Harper at the White House; FARC releasing its remaining hostages; the Mexican presidential campaign officially underway; Good Friday declared a holiday in Cuba; and Brazil’s currency hits a six-month low.

Harper and Calderón in Washington: Canadian Prime Minister Stephen Harper, Mexican President Felipe Calderón and U.S. President Barack Obama are meeting today for the North American Leaders’ Summit. According to a White House press release, the meeting will have a “particular focus on economic growth and competitiveness, citizen security, energy, and climate change.” AQ Editor-in-Chief Christopher Sabatini says, “President Obama has met with these two leaders more than any other world leaders; it makes perfect sense given our levels of trade and the importance of both countries to our security, though this fact has escaped attention.”

FARC Releasing Hostages: After announcing in February that it would release the 10 remaining hostages in its custody, the Fuerzas Armadas Revolucionarias de Colombia (FARC) will begin doing so today and later this week. The FARC has also announced that it will stop kidnapping civilians for money; asks Sabatini, “Could this be the end of the FARC?”

Campaign Season Underway in Mexico: On Friday the three leading candidates launched their presidential campaigns in a bid to succeed incumbent Partido Acción Nacional (PAN) President Felipe Calderón, who is term-limited from seeking re-election. Expect much attention to be paid to the first full week of official campaigning among the candidates—Enrique Peña Nieto (Partido Revolucionario Institucional, PRI), Andrés Manuel López Obrador (Partido Revolucionario Democrático, PRD), and Josefina Vázquez Mota (PAN). AQ Senior Editor Jason Marczak notes, “Although much of the campaign will focus on security policy, the next three months will also be crucial for further defining visions of other important issues, namely energy reform, competition, education, and fiscal policy. These issues must get their due attention as well.” Mexico votes on July 1.

Good Friday in Cuba: Pope Benedict XVI proffered during his visit to Cuba last week that Good Friday be declared a holiday in the island nation; over the weekend the Cuban government granted the papal request. This is particularly interesting for Cuba, which has a small Catholic population relative to other Latin American nations. Could this mean a growing influence of the Church in Cuba? Sabatini observes, “Religious space—any space—is important in Cuba. I hope, though, that the Pope’s trip helped produce more than this.”

Brazilian Currency Hits Six-Month Low: Bloomberg has reported that the value of the Brazilian real dropped to its lowest level since September 2011. How will President Dilma Rousseff respond? Despite much global fears about slowing growth in China, Rousseff expressed frustration with what she termed a “monetary tsunami” on the part of developed economies including the United States. Given that President Rousseff will hold a bilateral meeting with President Obama next week, pay attention to how currency discussion unfolds in the coming days.
