Araqchi and UK Foreign Secretary Edward Miliband held a telephone conversation on Friday to discuss bilateral relations as well as regional and international developments.
During the talks, Araqchi condemned Britain's inappropriate approach toward Iran, including its recent decision to designate the Armed Forces of the Islamic Republic of Iran, as well as London's complicity in the two wars imposed on Iran by the United States and the Zionist regime.
He described such policies as unjustified and stressed the need for the British government to reconsider its approach toward the Islamic Republic.
Referring to the US and Israeli military aggression against Iran as the main cause of the current regional situation, Araqchi said the Islamic Republic had entered the diplomatic process in good faith and finalized the June 18 understanding to end the war, but the US once again prevented its implementation by violating its commitments.
The Iranian foreign minister also reaffirmed Tehran's determination to establish operational mechanisms in cooperation with Oman to manage maritime traffic through the Strait of Hormuz, warning that interference by third parties would only further complicate the existing situation.
Araqchi further said any cooperation with the aggressors, including under the pretext of previous defense agreements, was unacceptable.
He emphasized that, under international law and the UN definition of aggression, allowing an aggressor to use a country's territory or facilities to launch an unlawful attack against another state constitutes an act of aggression and entitles the targeted country to exercise its legitimate right of self-defense.
For his part, Miliband outlined the policy of the UK's new government, saying Britain was not part of the war against Iran and believed diplomacy remained the best way to resolve disputes.
He also stressed the importance of maintaining diplomatic engagement with Iran to improve bilateral relations and help reduce regional tensions.
