Cuba hit out at the United States over its nearly 60-year-old embargo against the island nation, which Havana described as "even more cruel" given the suffering caused by the new coronavirus pandemic.
The communist-run single-party island is finding it tough to source medical supplies and has already recorded 564 coronavirus cases and 15 deaths.
The United States' economic-financial blockade is the most unfair, severe, prolonged system of sanctions of all time by one country against another.
The health system is the most affected because it affects the wellbeing of people.
The sanctions imposed by Washington have since 1992 permitted medicines to reach Cuba, as long as they're exclusively for the use of the people.
Donald Trump has ramped up the embargo since assuming the US presidency, making it harder for other countries to send supplies there.
Cuba complained recently that a shipment of test kits, masks and respirators donated by the Chinese Alibaba group didn't arrive because the American company tasked with transportation feared to breach US sanction rules.
