FILE - In this March 29, 2011 file photo, Venezuela's President Hugo Chavez, left, and Argentina's President Cristina Fernandez gesture before signing commercial accords during a visit to a state-run shipyard in Buenos Aires, Argentina. Fernandez is in Cuba on Friday, Jan. 11, 2013, to visit Chavez who is recovering from cancer surgery. The Venezuelan leader, normally at the center of national attention, is so ill following a fourth cancer surgery in Cuba that he has made no broadcast statement in more than a month, and has not appeared in a single photo. Officials have not specified what sort of cancer he suffers. (AP Photo/Natacha Pisarenko, File)
