"Over the past year of the [US] blockade policy, Cuba has suffered losses of over $4 billion," Penalver told a press conference.
The diplomat emphasized that Havana would continue demanding that the economic, trade and financial blockade by Washington be completely lifted.
"On October 31, 2018, the Cuban government will condemn the continuation of this policy and will again present a draft resolution [calling for the US sanctions to be scrapped] to the UN General Assembly," the ambassador stated.
The United States first imposed an arms embargo on Cuba in 1958. The embargo was followed by the introduction of restrictions in various other sectors. They include sanctions on financial transactions, trade, travel, among others.
The year 2015 marked rapprochement between Washington and Havana when the two nations restored diplomatic ties under the administration of then US President Barack Obama. A year later, the United States, which had repeatedly voted against removing the embargo, abstained from the United Nations' vote on the issue for the first time.
In 2017, the administration of US President Donald Trump announced a U-turn in the US policy toward Cuba, opting to retain the embargo on the Caribbean nation.
No Evidence of Cuba’s Alleged Involvement in Sonic Attacks
Cuban Ambassador to Russia Gerardo Penalver Portal also touched upon the topic of so-called sonic attacks on US diplomats, stating that the United States has no evidence of Cuba's involvement in the alleged incidents.
"Cuba has spoken from the outset of its willingness to cooperate in clarifying the circumstances of these so-called attacks. But the US government continued to produce accusations without any evidence. Clearly, they want to manipulate politics," he told a press conference.
More recently, US diplomats in China also complained of symptoms similar to those suffered by their colleagues in Cuba.
Last August, the US State Department said diplomats working at its embassy in Cuba were affected by an incident involving a mysterious audio device. Media reports at the time said some of the diplomats suffered permanent hearing loss and possible brain injuries due to a sonic weapon. Over 20 diplomats were affected, according to the State Department. The Cuban government has denied any involvement in the incidents.
