President Netumbo Nandi-Ndaitwah says Namibia will keep pushing for the unconditional lifting of the embargo while citizens mobilise humanitarian support for the Cuban people.
This is as the U.S. intensifies an economic embargo on Cuba, the latest being the blockade on energy supplies to the island.
The centenary of Fidel Castro's birth also turned the spotlight on Cuba's current economic hardships.
President Netumbo Nandi-Ndaitwah recounts that the impact of the blockade reaches far beyond economics, affecting access to medicine, basic services and opportunities for ordinary Cubans.
She says Namibia would continue to oppose unilateral sanctions and back Cuba's right to determine its own political and economic future.
"For more than six decades, Cuba has endured a unilateral economic and financial embargo imposed by the United States of America. The greatest cost of this embargo cannot only be measured in economic losses. It inflicts its greatest suffering upon ordinary citizens. We underline our principled call for the complete and unconditional lifting of the economic embargo against Cuba. No nation should be punished for exercising its sovereign right to determine its own political, economic and social path."
The Namibia-Cuba Solidarity Committee campaign has already raised seven hundred thousand dollars, but more support is needed.
The donated items, including medical supplies, are expected to provide immediate relief to communities facing shortages.
The Committee's Deputy Chair, Tuliameni Kalomoh, painted a grim picture of daily life in Cuba, induced by shortages of fuel, prolonged electricity outages and growing humanitarian needs.
"The humanitarian crisis in Cuba demands urgent and practical support from all of the people of Namibia. Only a device of our Cuban partners we have chosen, we have chosen to provide medicine and medical supplies as well as solar panels. You know, because of the denial of the blockade on oil, there's no electricity – one hour, two hours of electricity every day. The support we have received so far has been enthusiastic but woefully inadequate. And most of the support we receive has come from former combatants of the people of liberation health."
Even with diplomatic pressure mounting, Namibia says standing with Cuba is not about repaying a debt but honouring a friendship forged during the country's darkest years.
