"The important thing is that Spain and Iran have had highly positive relations and there is no problem for our interactions," Busquets told reporters in the northeastern province of Khorasan Razavi.
He added the two countries can take different steps to expand their relations in tourism and agricultural fields.
"Saffron and pistachio are two important Iranian products whose trade should receive more serious attention as they can be extensively traded in the world," Busquets underlined.
Iran and Spain in February signed two memorandums of understanding (MoUs) in Tehran in political, economic and rail transport fields.
The signing ceremony was held in the presence of Iranian Foreign Minister Mohammad Javad Zarif and his Spanish counterpart Alfonso María Dastis Quecedo.
Call for direct flights
Busquets stressed the need for setting up Madrid-Tehran direct flights to expand tourism ties between the two countries.
"During my stay in Iran, I have paid attention to this fact that Madrid-Iran flights should be launched," Busquets said at a meeting with provincial officials.
He added that 10,000 Spanish nationals travel to Iran annually.
"We should launch a direct line to send tourists to Iran and attract Iranian tourists to our country," Busquets said.
Iran and Spain in 2016 discussed facilitating visa issuance and setting up direct Tehran-Madrid flights.
