Zarif made the remarks in a meeting with Japanese Prime Minister's Special Envoy Masahiko Koumura in Tehran on Wednesday.
During the meeting, Zarif pointed to the agreements singed between Iran and Japan on development of economic relations, and expressed the hope that Japan would turn to be Iran's strong partner in the fields of politico-economics, such as transport, energy, oil and gas.
He also pointed to recent agreements on financing energy projects in Iran, and said preliminary works on these projects are underway and Iran believes the two countries could be good partners.
Zarif reminded Iran's principled stances on opposing usage or threatening to use nuclear weapons, and underscored the necessity for settlement of disputes peacefully and need for cooperation among important countries of the region in reducing tensions.
Masahiko Koumura, for his part, voiced pleasure for political, economic consultations with Iranian officials, and praised Iran's role in the region.
Japan respect Iran for commitment to its obligations, he added.
Koumura, heading a high-ranking delegation, arrived in Tehran on Tuesday and met President Hassan Rouhani on Wednesday.
He is due to meet and consult with other political and economic officials of Iran during his 3-day stay in Iran.
In relevant remarks last month, Japanese Minister of Economy Hiroshige Sekō stressed Tokyo’s plans for developing economic cooperation with Iran and providing the necessary supports in this regard.
"We are looking for broadening of economic and trade ties with Iran," the Japanese envoy said in a meeting with Iranian Deputy Foreign Minister Seyed Abbas Araqchi in Tokyo.
Sekō also voiced Japan’s strong support for the successful implementation of Iran’s nuclear deal, dubbed a Joint Comprehensive Plan of Action (JCPOA).
