Elias Jaua gave the details of Chavez health on his Twitter account on Monday after visiting the President in Cuba.
Jaua said that President Chavez also made decisions about the country’s participation in Community of Latin American and Caribbean States summit set to be held this week in Chile.
The President was "very happy because the Bolivarian dream continues advancing,” he also said.
"I transmit all his blessings and love for you, his beloved Venezuelan people. Viva Chavez!" Jaua added.
On Sunday, Vice President Nicolas Maduro said in a statement that the Venezuelan leader’s "vital signs and organ function are stabilizing, he is conscious and gaining strength for the next stage."
Maduro also gave assurances that the country is being governed well in the absence of its leader.
Maduro, elected by Chavez to rule in his absence, led the government after the new term started on January 10 after the Supreme Court unanimously decided that the current government could remain in office until Chavez takes the oath of office.
The 58-year-old Venezuelan president traveled to Havana on December 10 for a fourth operation after his cancer reappeared, despite a year and a half of treatment.
