The meetings were held on the sidelines of the 53rd edition of the Munich Security Conference (MSC) in Germany.
Heading a high-ranking delegation, Zarif arrived in the capital of the southern German state of Bavaria on Friday to take part in the MSC.
On Saturday, Zarif met with Iraqi Prime Minister Haider al-Abadi, Spanish Foreign Minister Jose Manuel Garcia-Margallo and his Ukrainian counterpart, Pavlo Klimkin.
The Iranian foreign minister also met with Slovenian President Borut Pahor and Yukiya Amano today.
The top Iranian diplomat is scheduled to deliver a speech at the Munich Security Conference on Sunday morning.
Since its foundation five decades ago, the MSC has become a leading international platform for dialogue on foreign and security policy.
In addition to its annual flagship conference, the MSC regularly convenes high-profile events on particular topics and regions and publishes the Munich Security Report.
