Havana, Cuba.- The general director for the United States Office of the Foreign Affairs Ministry of Cuba, Carlos Fernandez de Cossio, thanked the efforts made by U.S. congressmen to improve bilateral relations.

According to the Ministry’s webpage, the official acknowledged the willingness and contribution of Senators Patrick Leahy, Ron Wyden and Gary Peters, and representatives Jim McGovern, Kathy Castor and Susan Davis, who are part of a bipartisan delegation that is visiting the island since the weekend.

Fernandez de Cossio received the U.S. politician the day before, a meeting he described as constructive and in which he confirmed that there is no evidence of sonic attacks against American diplomats in Havana, as used by U.S. sectors interested in hindering any progress towards normalizing relations.

Led by Leahy, Senator from Vermont, Wyden (Oregon), Peters (Michigan), McGovern (Massachusetts), Castor (Florida) and Davis (California), the objective is to verify in the field the impact of the change in Washington policy towards island, from the arrival of Donald Trump to the White House, in January 2017.

Trump insists on strengthening the economic, commercial and financial blockade Washington has applied to Cuba for more than half a century and reversing some of the progress in bilateral ties achieved during 2015 and 2016, when high-level meetings were held and several cooperation agreements were signed.

The legislators foresee other meetings in this capital with authorities, small entrepreneurs and experts in the sectors of education, economy and biotechnology, in order to discuss prospects of improving economic opportunities for both peoples.

On Wednesday, the congressmen will offer a press conference at the U.S. Embassy in Havana.
