Mexico, Aug 11 (Prensa Latina) La Jornada daily on Wednesday echoed the Cuban scientists' condemnation of remarks made by US President Joe Biden, who tried to discredit their biotechnological competence. The newspaper noted that elite Cuban scientists promoted the signing of a letter to the president of the United States, who referred to Cuba as a failed state and discredited the capacity of the health and science system to face the challenges posed by the Covid-19 pandemic.
