Ecuadorian President Rafael Correa came on Monday to Havana to show solidarity with Chavez. "We came to embrace him on behalf of the Ecuadorian Fatherland," Correa said. "This is a gesture of solidarity with a brother at heart."
Chilean President Sebastian Pinera expressed his support for Chavez via Twitter, wishing him "much faith, strength and a speedy recovery."
"We will pray for his speedy recovery," Colombian President Juan Manuel Santos said via Twitter.
"Mexico expresses its best wishes for a successful surgery, as well as a full recovery of the Venezuelan president," said the Mexican government.
Venezuela's National Assembly Sunday approved the petition of Chavez to travel to Cuba for the new round of surgery. The 58-year-old has been fighting pelvic cancer since 2011 and has undergone three surgeries in the abdomen over the last 18 months.
