"Iran-Cuba relations need to reach their highest level in the political and diplomatic fields," Sheikh Hassani said.
The Iranian ambassador reiterated that Tehran and Havana have always been trying to expand political and economic exchanges over past 37 years.
Sheikh Hassani pointed to Iran's capacities for the expansion of mutual cooperation, and said, "Iran ranks first in the Middle East and seven in the world in nanotechnology."
In relevant remarks in late August, Cuban Trade and Investment Minister Rodrigo Malmierca Diaz in a meeting with Iranian Foreign Minister Mohammad Javad Zarif in Havana called for the broadening of trade and economic relations between the two countries.
During the meeting in the Cuban capital, Malmierca Diaz said that his country's private sector is ready to invest in Iran's economic projects.
"Havana is keen to develop relations with Tehran as a lasting partner and friend," he added.
Zarif and Malmierca Diaz discussed ways of development of cooperation between Tehran and Havana in the fields of energy, banking, health, nanotechnology and biotechnology.
"Cuba is ready to help facilitate development of cooperation between Islamic Republic and the Latin American states," Malmierca Diaz said.
Also in August, Iran and Cuba signed a memorandum of understanding (MoU) to boost the level of their economic and trade cooperation.
The cooperation document was signed on the sidelines of the first joint trade meeting of Iran and Cuba.
Iran attaches importance to the expansion of all-out ties with the Latin American countries.
