Fidel Castro has appeared on Cuban television for the first time in six months.
The 81-year-old former president was shown in conversation with Hugo Chavez, the Venezuelan president in images broadcast on Tuesday.
The silent video shows Castro and his younger brother Raul who succeeded him speaking with Chavez, who is helping build a new petrochemical refinery in eastern Cuba.
Raul Castro formally became Cuban president in February in a vote of the National Assembly after his older brother resigned.
Ailing leader
Castro has not been seen in public since falling ill almost two years ago.
He was shown in a video sitting outside laughing and talking with the two men, then standing as he bids Chavez farewell at the end of an hour-long meeting.
Castro, who has not fully recovered from intestinal surgery in 2006, led Cuba for 49 years after taking power in a 1959 revolution.
He was last seen in a video of a January meeting with Luiz Inacio Lula da Silva, the Brazilian president.
Castro writes occasional newspaper columns, but his long absence from public view had led to rumours that his health was failing.
Two Castros and Chavez were reported to have discussed a wide range of topics including a global food crisis and the US presidential election.
